Microstructure analysis for the quality control of TiAl components

摘要

The method involves subjecting component in relation to the material sample to a heat treatment, so that component or the sample is aged at a temperature. The phase is in a single form in the microstructure and microstructure in the heat treatment temperature s formed by quenching the component. The sample is frozen in the heat treatment. The sample or the component is subjected, after quenching of an investigation by X-ray diffraction to qualitatively or quantitatively to identify the phase.
