ageing steel

The test results showed that the peak hardness of ε-Cu precipitation dynamic curves occurred during ageing of steel; as the steel was pre-deformed the time occurred peak hardness of ε-Cu precipitation obviously decreased and the value of peak hardness increased appreciably.

试验结果表明，该钢在时效过程时，-εCu析出动力学曲线出现硬度峰值，当经过预变形处理后，-εCu析出峰值出现的时间显著降低，峰值高度明显增加。

Resolution the steel rolling problem of roll breakage with heat ageing method

用热时效法解决轧钢的断辊问题

The thermal ageing time has significant influence on strength and plasticity at room-temperature and tensile strength at high temperature of domestic steel, and so is long thermal ageing time on tensile strength at room-temperature and strength and plasticity at high temperature of French steel.

热老化时间对国产钢管的室温强塑性及高温抗拉强度有显著性影响，长时间热老化对法国钢管室温拉伸强度及高温强塑性的影响显著。
