Construction of index system of materials applicability evaluation

Materials applicability evaluation (MAE) in the field of equipments is to evaluate the technology readiness levels (TRL) of materials and the rationality of materials usage. To construct the index system of MAE, the construction principle is firstly built. Secondly, the main influence factors of materials applicability are analyzed, including materials properties, technology maturity, support capabilities and economic affordability. Based on the work mentioned above, the evaluation index system with orderly hierarchy, which includes the necessary key factors of materials engineering application, is founded via the administrative analysis method.
