PROCESS MAPPING OF COOLING RATES AND THERMAL GRADIENTS

摘要

A method performed by one or more processing devices includes conducting a plurality of tests of a manufacturing process. Each test is conducted at a different combination of at least a first process variable and a second process variable, and each test comprises locally heating a region of a structure, where the local heating results in formation of a thermal field in the structure, and assessing a temperature derivative of the thermal field. Based on results of the plurality of tests, a process map of the temperature derivative of the thermal field is generated, with the temperature derivative based on a function of the first process variable and the second process variable.
