采用不同的熱處理制度研究了退火和固溶時效溫度對TC18改進(jìn)型合金TC18A d16.5 mm絲材組織和性能的影響。結(jié)果表明：在720~780 ℃，隨著絲材退火溫度的升高，強(qiáng)度降低，塑性變化不大；但當(dāng)溫度超過780 ℃時，退火溫度對絲材拉伸性能影響不明顯；當(dāng)時效溫度一定時，隨著固溶溫度的升高，絲材強(qiáng)度增加，塑性降低；固溶溫度不變時，強(qiáng)度隨時效溫度的升高而降低，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.
