摘要
对Q370R进行了200～600℃温度下的屈服强度、抗拉强度等高温力学性能试验。通过试验发现,Q370R的屈服强度随试验温度的升高而降低,且温度在接近350℃时,屈服阶段基本消失;抗拉强度在200～400℃时,随试验温度的升高而增加;在400～600℃时,随试验温度的升高而降低。
The tests for high temperature mechanical properties of Q370R, such as the yield strength and the tensile strength at high temperature range from 200 ℃ to 600 ℃. Results showed that the yield strength was decreased with increase of temperature and the yield point was disappeared when the temperature approach the 350 ℃, the tensile strength was in- creased with the increased temperature from 200 ℃ to 400℃, while decreased with the increased temperature from 400℃ to 600 ℃.
