Abstract: 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 temperature 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.
