해양구조물강재의 절삭성능 평가 = Evaluation of machining performance of marine structural steel materials

다국어 초록 (Multilingual Abstract)

High-manganese steels designed to have an austenitic matrix structure are materials with excellent mechanical properties such as strength, toughness, and wear resistance. High manganese-containing steels with improved wear resistance are difficult to cut because they have low thermal conductivity and poor cold workability. Due to the strain hardening effect, wear resistance properties may further increase during the cutting process, which may adversely affect machinability and shorten cutting tool life. Correctly selecting the machining parameters of cutting tools is an important task. In this paper, we investigated the processing mechanism of high manganese steel applied to marine structures and analyzed wear characteristics.
