摘要

The superplasticity of Ti-46.7Al-2.2Cr(at.%)alloy was studied by mathematical induction.It is found that Zener Hollomon relative formula and there are serious deflections.According to the true superplastic stress and true strain curves,the deflection values of n=-7.46 and B=1439MPa are obtained,indicating that the limit of n>0 has been exceeded,which needs to be characterized by a negative sign.This shows that it conforms to the principle that the smaller n is,the better superplasticity is,but the problem that it has become a negative number needs to attract the attention of peers meantime B is a better match.
