Abstract: The team members used EBSD technology in "material analysis method" to study the martensite orientation dependence of high manganese TRIP steel on the innovative practice platform for college students. Under the guidance of teachers, the members comprehended the measurement process, learned EBSD sample preparation technology and EBSD analysis technology, and explored the martensite orientation dependence under different unidirectional compression deformation and the grain orientation rotation law of the austenite during the corresponding process in a quasi-in-situ manner.The project not only achieved obvious experimental results, but also the students exercised their hands-on ability and enriched their scientific research experience by participating in the experimental research process.In addition, it is also a beneficial attempt for the practical teaching of "material analysis method".

Key words: Material analysis method, Practical teaching, EBSD experiment
