Study on Microstructure and Tensile Properties of New γ-TiAl Alloy Sheet AITranslate
Abstract AITranslate
The microstructure of newγ-TiAl alloy sheet before and after rolling was investigated as well as its tensile properties after rolling.The results show that the forged microstructure before rolling mainly containsγphase,α2 phase and a certain amount of B2/βphase.After rolling,the coarse lamellar microstructure decreases and recrystallized isometricγgrains increase.The lamellar clusters are elongated along the rolling direction,and their broken degree is related to rolling deformation.The number of B2/βphase is significantly reduced due to high temperature rolling.After three cycles of heat treatment in the（γ＋α2）phase zone,the alloy lamellar microstructure increases,lamellar space decreases,and the microstructure is significantly refined.The high-temperature tensile plasticity of the sheet is relatively high,and its high-temperature tensile fracture mainly has the mixed features of translamellar facture,interlamellar facture and transgrain facture.
