A Determination Method of Key Process Parameters Affecting the Mechanical Properties of Alloy Materials

Abstract

The invention belongs to the field of metallurgy and particularly relates to a method for determining the key technological parameter influencing the mechanical property of alloy materials. The method includes the steps that historical mechanical property data y of alloy materials and a technological parameter x corresponding to the mechanical property are collected to serve as sample data, the degree of influence of the technological parameter on the mechanical property of alloy materials is determined qualitatively and quantificationally according to a two-step method, the determination result is subjected to experimental verification in the actual production process through mechanical property data obtained by changing the technological parameter according to the determined technological parameter having remarkable influence on the mechanical property of alloy materials, the optimal value range of the technological parameter x is finally determined according to the mechanical property data of the technological parameter under the condition of a historical value, and the optimal value range is applied to the actual production process. The method can find out the key technological parameter influencing the mechanical property of alloy materials rapidly within a short period, and solves the problems that coverage of analysis of causes for the alloy material quality problem is wide and troubleshooting difficulty is high.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to a method for determining key process parameters affecting the mechanical properties of alloy materials. Background technique [0002] When testing the mechanical properties of superalloy materials in the factory, there are often phenomena where the mechanical properties do not meet the standards. The reason analysis usually requires checking each process link in the production process one by one to find out the root cause of the problem, improve the production process plan, and improve product quality. [0003] The mechanical properties of superalloy materials are affected by many factors such as raw material composition, state, structure, specification, forging process, heat treatment process, and testing process. When quality problems occur, all relevant units must conduct quality analysis from the above aspects. Summarize and then comprehensively find the cause of the pro...
