在将电导率和硬度两者结合起来,应用于变形铝合金热处理状态确定理论分析的基础上,用数理统计方法之一——t检验法,分别对 Ly12合金在自然时效稳定态下,对应于一定置信水平的电导率和硬度值进行了估算。所得结果,为实际检测中的应用,提出了直接的判断依据。
Based on the theoretical analysis of determining the state of heat treatment of the deformed aluminum alloy by combining the conductivity and the hardness, the method of t test was used to analyze the thermal stability of the deformed aluminum alloy, Certain levels of conductivity and hardness values were estimated. The results obtained for the actual detection of the application, put forward a direct basis for judging.
