Abstract

The invention provides an optimization design method of Austempered ductile iron alloy composition based on Jmatpro material performance computation. The method comprises the following steps of: (1) selecting the change range of each element, and determining each component; (2) opening the Jmatpro software, calling a CastIron module and the corresponding database; (3) selecting the composition input software of one component, and selecting the material performance to be computed to compute; (4) computing end output curve graphs and data files; (5) sequentially repeating steps (3) and (4) to obtain the computation results of other components; (6) respectively comparing and analyzing each material performance of different compositions to obtain the optimal composition proportion. The alloy composition optimization method of the invention is simple and feasible; the method has strong theoretical support without much casting test and performance detection; the time is greatly saved, the efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a novel Aube ductile iron used for train wheels and an optimized design of its alloy composition. Background technique [0002] Austempered Ductile Iron (ADI) is widely called Austempered Ductile Iron in China. Its heat treatment is very similar to the austempering treatment of steel, and the microstructure obtained is composed of austenite and bainite very similar to steel. Because Aobei ductile iron has good comprehensive mechanical properties, low production cost, light weight, good wear resistance and fatigue resistance, excellent vibration reduction and sound absorption performance, Aobei ductile iron is popular in my country, Europe and the United States and other developed countries. It has received widespread attention and attention, and its output has grown at a rate of more than 15% per year. It is widely used in industries such as railway equipment, automobil...
