In August 2016, metal resistivity test system(RT~1000° C) with independent intellectual property rights was completed. It is a  a dynamic characterization tool for alloy heat treatment. It has high resistance measurement accuracy and convenient data management  function. We have applied for 5 relevant invention patents and software copyrights. The achievements were applied in the national key research and development plan (2016YFB0300400) "High performance tool and die steel" project.
