Introduction to G Tial Alloy

What is/are G Tial Alloy?

G Tial Alloy - Powder metallurgy is an important method for preparing TiAl alloys due to its ability to minimize grain size and eliminate compositional segregation. ^[1] A temperature gap (△Tp) corresponding to the peritectic transition exists in Nb containing TiAl alloys and the △Tp shows a parabolic shape on a plot of solute Al at constant Nb content. ^[2] In this work, we fabricated 4HSiC pMOSFET using TiAl alloy as contact metal to reduce the contact resistivity. ^[3] Furthermore, a second approach discussed covers microalloying TiAl alloys. ^[4] The mechanical properties of the β-solidifying TiAl alloy depended closely on the heat treatment. ^[5] Results show that the microcrack nucleation plays an important role in the fracture of multi-phase high Nb-containing TiAl alloys. ^[6] This study systematically investigated the influence of multi-directional forging (MDF) on the microstructural evolution, hot deformation behavior, and tensile properties of a β-solidifying TiAl alloy. ^[7] The appearance of deformation twinning in the α2 phase can play an important role for the excellent mechanical properties of high Nb containing TiAl alloys, which is of great importance for the further development of γ-TiAl alloys. ^[8] Joining TiAl alloy to Ni-based superalloy is of great interest for applications in aerospace and automobile field. ^[9] High Nb containing TiAl alloys have prospect to be used for turbo wheel and exhaust valve for vehicle engine. ^[10] Friction and wear properties of a high Nb-containing TiAl alloy against WC-8Co, Si3N4, and GCr15 in an unlubricated contact were investigated under various friction and wear conditions. ^[11] Dislocation glide governed the plastic deformation of the two directionally solidified C-containing TiAl alloys. ^[12] The aim of this study is to evaluate the potential use of titanium foil coated with sputtered silver and copper films as a novel brazing filler for joining TiAl alloys. ^[13] In this paper, the hot deformability and mechanical properties of a novel Mn- and Nb- containing TiAl alloy were studied systematically with the use of isothermal compression experiments. ^[14] The CCT behavior of a high Nb-containing TiAl alloy was experimentally investigated in the present study. ^[15] For the first time, the eutectoid decomposition α→τ1+γ and the crystalline orientation relationship in a Ru-containing TiAl alloy were studied. ^[16] A serious of diffusion bonding (DB) tests between high Nb containing TiAl alloy and Ti2AlNb alloy were conducted and the bonded joints were post-bonded heat treated (PBHT) at 1000 °C for 10h. ^[17] 3 GPa, which is much lower than that in the Nb-containing TiAl alloys. ^[18] In this work, corrosion behaviors of the high Nb-containing TiAl alloy with and without thermal barrier coatings are compared to illustrate the factors and corresponding mechanism determining stability of TiAl alloy in molten salts. ^[19]
