Every two years since 2017, HDMT co-organizes international conference on Heat Treatment and Surface Engineering, Materials and Tribology, Corrosion and Material Testing, called MTECH. The conference gathers high educated experts whose scientific and professional papers seek to further expand their knowledge and to network with each other. The focus is on metallic alloys, but contributions on other materials (polymers, ceramics, composites) are also of interest to this conference. The aim of the conference is to bring together specialists in material science and to discuss the state of the art from both theoretical and practical viewpoints.
