四、淬火系数分析法的应用 1、卧式热处理装置的设计淬火系数分析法首先被用来根据冷却曲线预测AA2024-T4合金的腐蚀形式.这是一个重要的工业性的问题,因为当时第一个大型卧式薄板连续热处理炉正在设计.在设计这种薄板材淬火设备的时候,有很多可供选用的建议.目的是使淬火薄板得到最好的性能和最小的翘曲.设计师们已有一种模型,按该模型,采用两阶段淬火法可以减少翘曲,即初始阶段的低速淬火和随后的高速淬火.然而,没有一种模型能预测沉淀硬化铝合金经不同流程淬火后的性能.选用了
Fourth, the application of quenching coefficient analysis 1, the design of horizontal heat treatment device quenching coefficient analysis method is first used to predict the corrosion curve of AA2024-T4 alloy according to the cooling curve.This is an important industrial problem, because the first A large horizontal thin plate continuous heat treatment furnace is being designed.When designing this thin sheet quenching equipment, there are a lot of options for the purpose of the quenching sheet is designed to get the best performance and minimum warp.The designers have There is a model by which a two-stage quenching method can be used to reduce warping, ie low-speed quenching in the initial stage followed by high-speed quenching.However, none of the models predict the performance of a precipitation hardened aluminum alloy after being quenched by different processes.
