Stress-induced Transformations in Ti-mo Alloys

Beta Ti Alloys with Low Young’s Modulus

Composition dependence of Young’s modulus in Ti-V and Ti-Nb binary alloys and Sn-added ternary alloys quenched from phase region was investigated at room temperature in relation to the stability of phase. A minimum of Young’s modulus in the binary alloys appears at such a composition that athermal ! phase transformation is almost completely suppressed. Formation of isothermal ! phase by aging a...

Phase transition and ordering behavior of ternary Ti – Al – Mo alloys using in - situ neutron diffraction

Neutron diffraction has been used for in-situ investigations to elucidate the phase transformation behavior of two Mo-containing TiAl alloys with compositions of Ti-44Al3Mo and Ti-44Al-7Mo (in at.%). Five different phases are present in these alloys. These include three ordered phases at room temperature, namely a2, b0 and c and two disordered phases, a and b, which occur at higher temperatures...

Pseudo-elastic deformation behavior in a Ti/Mo-based alloy

It is shown that the pseudo-elastic response in a series of Ti–Mo–V–Nb–Al alloys with 8–11 wt.% Mo is highly sensitive to both composition and heat treatment. Recovery of up to 3.0% strain has been observed but it appears that this may not be due to reversible formation of a00 martensite. 2003 Acta Materialia Inc. Published by Elsevier Ltd.

Rotations of brittle particles during plastic deformation of ductile alloys

Experimental evidence is presented to show that significant rotations of brittle phase inclusions of a Fe-rich intermetallic phase occur during plastic deformation on an Al Mg Si base wrought aluminum alloy. The particle rotations are quantitatively characterized, for uniaxial tension, compression, torsion, and notch-tension test specimens strained to different strain levels. The particle rotat...
