Abstract

A model for the creep of tantalum at elevated temperature has been presented in which the increase in strain rate with strain is related to the reduction of .the cross-sectional area accompanying strain. Comparison of experimental data with the proposed theory indicates that the dominant creep mechanism beyond the second stage of creep starts at a point of highest temperature or at a stress concentration, spreads throughout the volume in the immediate vicinity, and eventually results in localized "necking down."
