Yonggang Sun,Changjiang Zhang,Hong Feng,Shuzhi Zhang,Jianchao Han,Jianchao Han,Wanggang Zhang,Ertuan Zhao,Hongwei Wang +8 more
TL;DR: In this paper, the effect of deformation temperature on microstructure evolution and mechanical properties of a near α titanium alloy during isothermal multiple die forging (IMDF) is systematically investigated.
Journal ArticleDOI
Deformation behavior of high Nb containing TiAl based alloy in α + γ two phase field region
TL;DR: In this article, the deformation mechanism of α phase is dynamic recovery at 1275°C, whereas γ phase is mainly dynamic recrystallized, and the reasons of the different deformation behavior between 1225°C and 1275 ǫ c, as well as the difference deformation behaviour between α and γ phases are analyzed.
Journal ArticleDOI
The microstructure, mechanical properties, and oxidation behavior of beta-gamma TiAl alloy with excellent hot workability
TL;DR: In this article, a new type beta-gamma TiAl alloy of nominal composition of Ti-44Al-4Nb-4V-0.3Mo-Y (at%) was fabricated by induction skull melting, which was designed based on the study of the microstructural effects of Mo, Cr, V, and Nb on TiAl Alloy.
Journal ArticleDOI
Effects of direct rolling deformation on the microstructure and tensile properties of the 2.5 vol% (TiBw+TiCp)/Ti composites
TL;DR: In this article, the microstructure evolution and tensile properties of the composites during direct rolling were investigated, and the results showed that increasing of the rolling deformation contributes to the refinement of primary α phase (αp) and the improvement of the distribution uniformity of TiBw and TiCp.
Journal ArticleDOI
Microstructure and tensile properties of hot fogred high Nb containing TiAl based alloy with initial near lamellar microstructure
TL;DR: In this article, a quasi-isothermal forged as-forged alloy with a nominal composition of Ti-44Al-8Nb-0.2B-Y (in at%) exhibiting near lamellar microstructure was fabricated.
