摘要: It is the intent of this communication to present and discuss some data regarding kinetics primary creep a two phase gamma TiAl alloy which had been studied previously determine mechanisms giving rise minimum strain rate. In order study an approach taken by Dorn et al also recently employed Argon Bhattacharya was taken. demonstrated that at given constant stress, rate during governed combined time-temperature parameter [Theta] = t exp([minus]Q/RT) where Q activation energy for self diffusion many times governs process steady-state creep. shown same stress level all curves were found collapse on one another when plotted as function [Theta][sup (9)].
