Abstract

An optimal design method of Aube ductile iron alloy composition based on Jmatpro material performance calculation, including the following steps: (1) first select the range of each element change, and determine each component; (2) open Jmatpro software, call the Cast Iron module and Corresponding database; (3) Select the composition of a component and input it into the software, and select the material properties to be calculated for calculation; (4) Output the graph and data file after the calculation; (5) Repeat steps (3) and (4) in sequence , to obtain the calculation results of the remaining components; (6) Comparatively analyze the properties of each material under different components, and obtain the optimal composition ratio. The alloy composition optimization method of the present invention is simple and easy to implement, has strong theoretical support, does not require a large number of trial castings and performance tests, greatly saves time, improves efficiency, and reduces costs.

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...
