峰值硬度
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。
The addition of Cd promotes the age-hardening process of Al-Si-Cu-Mg alloy, increases the peak hardness and reduces the time to reach peak hardness.
合金元素Cd的添加促进了铸造Al-Si-Cu-Mg合金的时效过程,提高了合金的峰时效硬度,加快了合金的硬化速度。
