Processing maps for hot deformation of α2 aluminide alloy Ti-24Al-11Nb
TLDR
Using the test data of α2 titanium aluminide alloy Ti-24Al-11Nb with microstructural observations, studies were made to examine the flow localization concepts as well as the simplified metallurgical stability criterion for delineating the regions of flow instabilities in the processing maps.Abstract:
Using the test data of α2 titanium aluminide alloy Ti-24Al-11Nb with microstructural observations, studies are made to examine the flow localization concepts as well as the simplified metallurgical stability criterion for delineating the regions of flow instabilities in the processing maps. The optimum hot working conditions for the material are suggested.read more
