Notes:
The titanium alloys containing the Nb transition elements have been investigated as theNi-free shape memory and the biomedical alloys with a low elastic modulus. The mechanicalproperties of the alloys depended upon the meta-stable phases like the α`, α``, ω. To study themartensitic transformations from the β to α`` or α` the Ti-xNb (x=0 to 40 wt%) alloys were meltedinto the button type ingots using a VAR, and followed by the water-quenching after the soaking at1000oC for 2hrs. The crystallography of the martensitic phases in the water-quenched alloys wasanalyzed using a XRD. The diffraction peaks of the orthorhombic martensites were identified by thecrystallographic relationship with the bcc matrix. The lattice parameters of the orthorhombicmartensites were varied continuously with the contents of the Nb elements. The martensitictransformations of the alloys were studied using the phenomenological theory of Bowles andMackenzie
