Work Hardening Behavior(加工硬化行为)研究综述
Work Hardening Behavior 加工硬化行为 - Tensile properties that depend on t/d are inferred to be affected by work-hardening behavior, enhanced by twinning deformation in hcp titanium. [1] In this study the strain capacity and work-hardening behavior of bainite (B), bainite + polygonal ferrite (B + PF), and bainite + polygonal ferrite + pearlite (B + PF + P) microstructures are compared. [2] Furthermore, the onset and end of stages II of work-hardening behavior are advanced and the work-hardening rate in stage II increases faster with increasing grain size and foil thickness. [3] Ductility of metallic materials is influenced by their work-hardening behavior, which in turn varies with respect to grain refinement. [4] The tensile stress–strain curves of the specimens show obvious work-hardening behavior after yielding at RT, 600 °C and 700 °C, while it decreases obviously, and the stress basically maintains a constant at 760 °C, 800 °C and 900 °C. [5] The HGS promotes the continuously increased geometrically necessary dislocations (GNDs) density, which, combined with the nano-spaced stacking fault (SF) networks, leads to the outstanding three-stage work-hardening behaviors during tensile tests at 293 K and 77 K. [6] It is because that two controversial theory (deformation twins induced dynamic Hall and Petch effect vs Portevin-Le Ch a ˆ telier effect) have been long existed and both are thought of contributing to the resulting work-hardening behavior during straining of TWIP steels. [7] The densities of the SFs and the HCP laths have a considerable influence on the work-hardening behavior. [8] Engineered Cementitious Composite (ECC) is a high-efficiency composite material that possesses work-hardening behavior in addition to its multiple-cracking specifications. [9] Firstly a generalized formula considering work-hardening behaviors (Pilling-up or Sinking-in) between contact area and interference is proposed for fully plastic regime based on the definition of plastic contact area index. [10] The martensitic transformation of B2–CuZr phases and the deformation of the Ta-rich particles cooperatively contribute to the plasticity and work-hardening behavior of the composites. [11] The work-hardening behavior was initially induced by austenite, and then by the strain-induced e-martensite (SIMe); finally, it was SIMα′ that pronouncedly affected the work-hardening behavior at 298 and 253 K. [12] In the case of β-type alloys, the addition of Nb improves the bonding energy between atoms, reduces the grain size, increases the elastic modulus, improves the yield strength and renders superior work-hardening behavior. [13] During the multi-pass tests, the work-hardening behavior of the material controls the evolution of the microstructures beneath the scratch. [14] 044%) resulted in the appearance of inclusion clusters in dimples, which were detrimental to fracture and work-hardening behavior. [15] The aim of this research is to investigate the microstructural changes and work hardening behavior of AISI 316L 0. [16] The work hardening behaviors of both cases showed three-stage variation, successively ascribed to the dislocation glide of ferrite, TRIP effect of retained austenite and dislocation intersection/tangle of ferrite and martensite, respectively. [17] The purpose of this paper is to investigate the work hardening behavior and energy absorption characteristic of metallic foams and functionally graded foam filled tubes, including single-, double- and triple-layer foams. [18] This research is to establish a stress–strain model capable of predicting both the Luders elongation and work hardening behaviors of F-P steels subjected to room temperature tension. [19] Moreover, the texture has a substantial influence on work hardening behavior. [20] Its mechanical response and work hardening behavior during uniaxial compression were deeply analyzed to investigate the competition mechanism between basal slip and detwinning. [21] The austenite stability determines the three types of work hardening behavior. [22] Herein, the effect of initial grain size was considered as a function of Hall-Petch strengthening, where experimental validation revealed very good accuracy on predicting the work hardening behavior, peak stress, peak strain and flow softening with varying grain morphologies. [23] The work hardening rate was found to increase with decreasing temperature and increasing strain rate, while strain rates had great effects on work hardening behavior. [24] It was found that the addition of either as-quenched or tempered athermal martensite led to an improvement in mechanical properties as compared to a ferrite plus austenite medium manganese steel, although the yielding and work hardening behavior were highly dependent upon the martensite characteristics. [25] The work hardening behavior was discussed on the basis of the phase transformation theory and dislocation strengthening. [26] The work hardening behavior is analyzed by C-J analysis method. [27] This makes crucial to understand anisotropic material properties and work hardening behavior of a material. [28] The effects of friction stir processing (FSP) on microstructures, tensile properties and work hardening behavior of reduced activation ferritic/martensitic steel (RAFM) under different rotation speeds were investigated. [29] In this paper, the microstructure evolution, mechanical properties and work hardening behavior with Bi-modal structure were studied in detail. [30] The study of commercial Ti-alloy wires is considered wherein to overcome this limitation, the formulation of the Kocks–Mecking (K–M) model is modified to provide a parameter cb that characterizes the microstructural scale responsible for the observed plasticity and work hardening behavior. [31] The effect of thermo-mechanical processing of 9Cr-1W-TaV reduced activation ferritic martensitic (RAFM) steel on tensile flow and work hardening behavior has been studied and compared with RAFM steel in Normalized and Tempered (N + T) condition. [32] The work hardening behavior and deformation microstructures of pure Cu and Cu-Mn alloys were systemically investigated under uniaxial compression. [33]据推断，取决于 t/d 的拉伸性能受加工硬化行为的影响，并通过 hcp 钛中的孪晶变形增强。 [1] 本研究比较了贝氏体 (B)、贝氏体 + 多边形铁素体 (B + PF) 和贝氏体 + 多边形铁素体 + 珠光体 (B + PF + P) 微观结构的应变能力和加工硬化行为。 [2] 此外，第二阶段的加工硬化行为的开始和结束提前，第二阶段的加工硬化速率随着晶粒尺寸和箔厚度的增加而增加得更快。 [3] 金属材料的延展性受其加工硬化行为的影响，而加工硬化行为又随着晶粒细化而变化。 [4] 试件的拉伸应力-应变曲线在室温、600 ℃和700 ℃屈服后表现出明显的加工硬化行为，同时明显减小，在760 ℃、800 ℃和900℃时应力基本保持恒定。摄氏度。 [5] HGS 促进了不断增加的几何必要位错 (GND) 密度，与纳米级层错 (SF) 网络相结合，在 293 K 和 77 K 的拉伸试验中产生了出色的三阶段加工硬化行为。 [6] 这是因为两个有争议的理论（变形孪晶引起的动态霍尔效应和 Petch 效应与 Portevin-Le Ch a telier 效应）早已存在，并且两者都被认为有助于在 TWIP 钢的应变过程中产生加工硬化行为。 [7] SF 和 HCP 板条的密度对加工硬化行为有相当大的影响。 [8] 工程水泥复合材料 (ECC) 是一种高效复合材料，除了具有多重开裂规格外，还具有加工硬化行为。 [9] 首先，在定义塑性接触面积指数的基础上，提出了一种考虑接触面积与干涉之间加工硬化行为（Pilling-up or Sinking-in）的广义公式。 [10] B2-CuZr相的马氏体相变和富Ta颗粒的变形共同促进了复合材料的塑性和加工硬化行为。 [11] 加工硬化行为最初是由奥氏体诱导的，然后是由应变诱导的 e-马氏体 (SIMe) 诱导的；最后，是 SIMα′ 显着影响了 298 和 253 K 的加工硬化行为。 [12] 在 β 型合金的情况下，添加 Nb 提高了原子间的结合能，减小了晶粒尺寸，增加了弹性模量，提高了屈服强度并提供了优异的加工硬化性能。 [13] 在多道测试期间，材料的加工硬化行为控制着划痕下方微观结构的演变。 [14] 044%）导致在凹坑中出现夹杂物簇，这对断裂和加工硬化行为是有害的。 [15] 本研究的目的是研究 AISI 316L 0 的微观结构变化和加工硬化行为。 [16] 两种情况下的加工硬化行为均呈现出三个阶段的变化，依次归因于铁素体的位错滑移、残余奥氏体的TRIP效应以及铁素体和马氏体的位错交叉/缠结。 [17] 本文的目的是研究金属泡沫和功能梯度泡沫填充管（包括单层、双层和三层泡沫）的加工硬化行为和能量吸收特性。 [18] 本研究旨在建立一个应力-应变模型，该模型能够预测 F-P 钢在室温拉伸下的 Luders 伸长率和加工硬化行为。 [19] 此外，织构对加工硬化行为有很大影响。 [20] 深入分析了其在单轴压缩过程中的力学响应和加工硬化行为，研究了基底滑移和去孪晶之间的竞争机制。 [21] 奥氏体稳定性决定了三种加工硬化行为。 [22] 在此，初始晶粒尺寸的影响被认为是 Hall-Petch 强化的函数，实验验证表明在预测不同晶粒形态下的加工硬化行为、峰值应力、峰值应变和流动软化方面具有非常好的准确性。 [23] 发现加工硬化率随着温度的降低和应变率的增加而增加，而应变率对加工硬化行为有很大的影响。 [24] 研究发现，与铁素体加奥氏体中锰钢相比，加入淬火或回火无热马氏体可以改善机械性能，尽管屈服和加工硬化行为高度依赖于马氏体特性。 [25] 在相变理论和位错强化的基础上讨论了加工硬化行为。 [26] 加工硬化行为采用C-J分析法进行分析。 [27] 这对于理解材料的各向异性材料特性和加工硬化行为至关重要。 [28] 研究了搅拌摩擦加工 (FSP) 对不同转速下还原活化铁素体/马氏体钢 (RAFM) 的显微组织、拉伸性能和加工硬化行为的影响。 [29] 本文详细研究了双峰结构的显微组织演变、力学性能和加工硬化行为。 [30] 考虑商业钛合金线材的研究，其中为了克服这一限制，修改 Kocks-Mecking (K-M) 模型的公式以提供参数 cb，该参数表征负责观察到的塑性和加工硬化行为的微观结构尺度. [31] 研究了 9Cr-1W-TaV 减少活化铁素体马氏体 (RAFM) 钢的热机械加工对拉伸流动和加工硬化行为的影响，并与 RAFM 钢在正火和回火 (N + T) 条件下进行了比较。 [32] 系统研究了纯Cu和Cu-Mn合金在单轴压缩下的加工硬化行为和变形显微组织。 [33]
Unique Work Hardening Behavior
Homogeneous co-deformation mediated by heterogeneous interfaces and columnar grain boundaries promotes a unique work hardening behavior. [1] The in-plane anisotropic, the tension-compression asymmetric, and the unique work hardening behaviors of the CP-Ti sheets are ascribed to available deformation mechanisms. [2]由异质界面和柱状晶界介导的均质共变形促进了独特的加工硬化行为。 [1] CP-Ti 片材的面内各向异性、拉伸-压缩不对称和独特的加工硬化行为归因于可用的变形机制。 [2]
Different Work Hardening Behavior
The fine-grained and coarse-grained samples showed different work hardening behaviors during room temperature tensile deformation. [1] However, the formation of the deformation twinning was suppressed with decreasing the grain size, resulting in different work hardening behaviors. [2]细晶粒和粗晶粒试样在室温拉伸变形过程中表现出不同的加工硬化行为。 [1] 然而，随着晶粒尺寸的减小，变形孪晶的形成受到抑制，导致不同的加工硬化行为。 [2]
work hardening behavior induced
As the percentage of pre-precipitated δ phases is raised, the obvious work hardening behavior induced by the intense interactions between δ phases, grain boundaries and substructures occurs in the initial hot forming process. [1] ,Results showed that the hydrogen led to the plasticity of the samples reduced significantly, together with the distinct work hardening behavior induced by hydrogen charging during plastic flow stage. [2]随着预析出的δ相百分比的提高，在初始热成形过程中，δ相、晶界和亚结构之间的强烈相互作用导致明显的加工硬化行为发生。 [1] ,结果表明，氢气导致样品塑性显着降低，同时在塑性流动阶段充氢引起明显的加工硬化行为。 [2]
