Structure and properties of low modulus titanium alloy Ti–26Nb–7Mo–12Zr

Abstract

The calculation of the choice of a new low modulus titanium β alloy was described. The investigations of the structure and properties (mechanical, tribological and corrosive) of low modulus titanium β alloy Ti–26Nb–7Mo–12Zr after mechanical–thermal processing were carried out. An analysis of the results of experimental research showed that the formation of homogeneous fine grained structure by sheet rolling with subsequent annealing before quenching leads to decreased elastic modulus, increased plasticity and wear resistance. Therefore, new titanium β alloy designed in the present study, Ti–26Nb–7Mo–12Zr, is expected to have good properties as biomaterial.
