Microstructure and microhardness evolution of Ti-10V-2Fe-3Al alloy under tensile/torsional deformation modes
Source abstract
Abstract
Abstract Microstructure and microhardness evolution of a metastable Ti-10V-2Fe-3Al (Ti-1023) alloy were systematically investigated under uniaxial tension (UT), single torsion (ST), and simultaneous tension-torsion (STT) deformation at ambient temperature. The results show that stress-induced α″ martensite transformation has been activated which its volume fraction depends heavily on the deformation modes. There are groups of α″ structures with various morphology generated from the grain boundaries of separate β grains, which long strip-like and block-shaped structures after UT, zig-zag, needle-shaped, and block-shaped structures after ST, a combination of zig-zag, needle-shaped, block-shaped, and strip-shaped structures after STT were observed. Moreover, there is an apparent dynamic grain refinement and accumulation of geometrically necessary dislocations (GNDs) by UT, ST and STT deformation, and STT deformation mode is more conducive to the two effects. The average Vickers microhardness of as-received, UT, ST, and STT samples are ~295 HV, ~311 HV, ~324 HV, and ~351 HV. It is closely related to the dynamic grain refinement caused by the TRIP effect and GNDs accumulated.
