Mechanical Properties of Commercially Pure Titanium during Hot Compression
Commercially pure titanium (CP Ti), grade II, is subjected to hot compression at temperatures ranging from 673 to 973 K with 50 K intervals and strain rates of 0.001, 0.01, 0.1 and 1s-1 up to 60% height reduction. By analysing work hardening rate vs. flow stress, the deformation behaviour can be divided into three groups, viz. three-stage work hardening, two-stage work hardening and flow softening. By plotting the data in a T vs. logε diagram, the present and previous data fall into three distinct domains which can be separated by two distinct values of the Zener-Hollomon parameter.
