Effect of prestress on tensile yield strength of a Ni3Al alloy

  • M. H. Yoo (a1) and C. T. Liu (a1)

Abstract

An experimental technique of prestressing and quenching was employed in order to elucidate the nature of pinning points responsible for the anomalous yield strength of Ni3Al. The apparent number density of pinning points at room temperature was found to be unaffected by the prestressing and quenching from elevated temperatures. This result is consistent with the crossslip-pinning (CSP) model in that cross-slipped segments act as pinning points on the leading superpartial dislocations.
