采用不同的热处理制度研究了退火和固溶时效温度对TC18改进型合金TC18A d16.5 mm丝材组织和性能的影响。结果表明：在720~780 ℃，随着丝材退火温度的升高，强度降低，塑性变化不大；但当温度超过780 ℃时，退火温度对丝材拉伸性能影响不明显；当时效温度一定时，随着固溶温度的升高，丝材强度增加，塑性降低；固溶温度不变时，强度随时效温度的升高而降低，塑性增加。

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.
