EFFECTS OF CHROMIUM CONTENT AND IMPACT LOAD ON MICROSTRUCTURES AND PROPERTIES OF HIGH MANGANESE STEEL Pham Mai Khanh, Nguyen Duong Nam, Le Thi Chieu, Hoang Thi Ngoc Quyen School of Materials Science and Engineering, Hanoi University of Science and Technology No1, Dai Co Viet Road, Hai Ba Trung District, Ha Noi, VIET NAM e.mail: khanh.phammai@hust.edu.vn Keywords: High Manganese steel, impact load, twinning, transition layer Abstract In this paper, the effects of Cr content and impact load on the microstructure and properties of High Manganese Steel (HMS) were investigated.
Due to its properties, HMS is accepted as a very popular engineering material.
This steel used chiefly in equipment for handling and processing earthen materials as rock crushers, grinding mills, power-shovel buckets, cane teeth and pumps for handling and in a multitude of classed applications. [1] There are a lot of researches about the effect of elements alloying on microstructures and mechanical properties of Austenitic High Manganese steel.
