对一系列高强铝合金(2024、2014、7076、7012)在连续升温过程中的电阻率进行了测量,这个方法在确定稳定相及亚稳定相的溶解或沉淀的临界温度方面表现出很高的精确性。因此,可以给出合金在不同冶金状态下的准确特性,借助于差示扫描量热法获得的补充量热数据,解释了用扫描电阻法获得的数据。讨论了这种方法作为研究和质量控制的补充技术的适用性。
The resistivity of a series of high-strength aluminum alloys (2024, 2014, 7076, 7012) during a continuous temperature increase was measured and this method shows a high degree of determination in determining the critical temperature for dissolution or precipitation of the stable and metastable phases Accuracy. Therefore, the exact characteristics of the alloy under different metallurgical conditions can be given, and the data obtained by the scanning resistance method are explained by means of the supplementary amount of thermal data obtained by differential scanning calorimetry. The applicability of this method as a complementary technique to research and quality control was discussed.
