Martensite Formation and Decomposition in Alloys of Titanium Containing β-Stabilizing Elements
An investigation is reported of martensite formation in certain Ti-Mo, Ti-V and Ti-Nb alloys and of the decomposition of martensite on ageing. A transition from hexagonal to orthorhombic martensite occurred with increase in solute content. On ageing the orthorhombic martensite structures, spinodal decomposition took place, accompanied by substantial strengthening. Reversion of α” to β can also occur in some alloys.
