Papers by Keyword: Strain Rate Sensitivity Exponent

Abstract: High temperature tensile properties of Ti-4Al-6V material were obtained through high temperature tensile test, and processing maps of the material were drawn by Matlab, then strain rate sensitivity exponent m was calculated. The value of m obtained through constant strain rate stretching method was compared to the former. The results showed that processing map could not only predict the good workability region and flow instability region but also calculate the value of m accurately.
