淬火技术,从齿轮的简单浸淬到复杂的压淬,在汽车制造业中的应用非常广泛。由于在制造过程中会发生复杂的物理现象,所以为了获得要求的性能,淬火工艺参数的选定也很复杂。近几十年来,已成功地采用计算机模拟来优化热处理工艺。本文列举了一些实例来阐述模拟技术的状况,包括淬火过程的物理现象,用于预测汽车零件热处理后的显微组织、力学性能和畸变的耦合模型的理论背景。
Quenching technology, from the simple gear dip to complex complex quenching, in the automotive industry is widely used. Due to the complicated physical phenomena that occur during the manufacturing process, the selection of the quench process parameters is also complicated in order to obtain the required properties. In recent decades, computer simulations have been successfully used to optimize the heat treatment process. This article gives some examples to illustrate the state of the simulation technology, including the physical phenomena of the quenching process, the theoretical background of a coupled model for predicting the microstructure, mechanical properties and distortion of automotive parts after heat treatment.
