Optimization and control of metallurgical properties during homogenization of an alloy

摘要

The homogenization cycle of an alloy is optimized and controlled by defining a target degree of transformation to achieve at least one metallurgical property for an alloy. The desired metallurgical properties include, but are not limited to, dissolving precipitation hardening phases, transforming insoluble phases into preferred phases and precipitating the dispersoid phases to the proper size and distribution. Using regression analysis, a transformation model is obtained to predict the degree of transformation of an alloy by analyzing the degree of transformation of a plurality of sample alloys subjected to heating at predetermine temperatures for predetermined amounts of time.
