钨对高锰钢显微组织和冲击韧性的影响
Effect of W on Microstructure and Impact Toughness of High Manganese Steel
摘要
Abstract
The investigation was carried out to study the effect of tungsten addition (0-1.460％) on the microstructure and impact toughness of the high manganese steel by metallographic microscope, scanning electron microscopy, electronic probe and mechanical properties tests. The results indicate that with the increase of W content, the grain size of high manganese steel decreased, and the matrix hardness of high manganese steel increased. A small amount of carbides which contained a lot of W was precipitated on the matrix of high manganese steel; the impact toughness of high manganese steel first increased, then decreased, and reach the maximum 329.9 J/cm2 when W content was 0.912％, which increased by 49％ compared with that of the high manganese steel without W. This is contributed to the combined action of solid solution strengthening, grain refinement strengthening and precipitation of carbides.关键词
