Influence of heat treatment process on microstructure and mechanical property of TC18A alloy wire

The influence of annealing and solution+aging temperatures on microstructure and mechanical property was studied.The results show that between 720℃and 780℃,with increase in annealing temperature,strength of wire decreases,while plasticity has no obvious change.But above 780℃,the influence of annealing temperaiture on tensile property is not obvious.When aging temperature keeps constant,strength increases and plasticity decreases with increase in solution temperature.When solution temperature keeps constant,strength decreases and plasticity increases with increase in aging temperature.
