The Deformation Mechanism and Alloying Behavior of TiAl Intermetallic Compound. (1998)
Pu, Zhongjie, Zhu, Jing, Zou, Dunxu, Cai, Qigong
The main deformation mode in TiAl based alloys was the glide of superdislocation rather than ordinary dislocation in Al-rich Ti-54Al alloy at room temperature and 77K, for Ti-rich TiAl based binary...
Hot Deformation Behaviors of TiAl-3 at%Cr Alloy. (1998)
Pu, Zhongjie, Zou, Dunxu, Zhu, Jing, Cai, Qigong, Zhong, Zhengyong
An investigation of the hot deformation behavior of Ti-46.5 at%Al-3at%Cr alloy from 1173-1473 K with strain rate of 0.001 to 0.1 1/s was conducted; the true stress-strain curve showed a peak stress...
The Effect of Microstructures on Mechanical Behaviors of Ti2AlNb Intermetallic Compounds. (1998)
Wang, Liming, Yao, Mei, Zou, Dunxu, Zhu, Dong, Cai, Qigong
Samples of Ti2AlNb were heat treated to obtain a beta-phase microstructure. Mechanical properties were studied in terms of the microstructure. O-phase precipitation is used as an explanation of the...
Anomalous Strain Rate Dependence of the Flow Stress in TiAl Intermetallic Compounds. (1998)
Zhu, Dong, Wang, Liming, Zou, Dunxu, Yao, Mei, Cai, Qigong
An attempt was made to study the occurrence of the decrease in flow stress in polycrystalline TiAl. The factors influencing plastic deformation are also discussed.
Zhu, Dong, Wang, Liming, Yao, Mei, Zou, Dunxu, Cai, Qigong
Plastic deformations of TiAl and TiAl-V intermetallic compounds have been studied by compression experiment at various temperatures and strains rates. The results showed that plastic deformation was...
