Abstract

Precipitation-strengthened aluminium alloy type 2618-T61 was subjected to symmetric and tension-hold reverse strain-controlled cyclic loading at 150°C. The symmetric cyclic loading did not affect the resultant fracture toughness of the alloy but the tension-hold loading did. The reduction in fracture toughness was related to weakening of the grain boundaries by the prior tension-hold type of reverse loading.
