YIELD POINTS IN ALPHA-CU-AL SINGLE CRYSTALS
Abstract
A yield point effect attributed to short-range ordering (SRO) occurs in Cu base Al. The yield drop at 296 K varies with heat treatment, decreasing as the annealing temperature is raised from 433 to 598 K. Yield drop (523 K anneal, measured at 77 K) is approximately proportional to (c sub Al (1-c sub Al)) squared, where c is the atomic concentration of the solute. The variation of yield drop with strain rate and testing temperature is also consistent with the idea that it is associated with SRO. (Author)
