冲击能量不同，高锰钢的磨损规律有不同的表现．纳米晶、非晶态是高能量冲击载荷下高锰钢特有的亚结构；高密度变形条带相互交叉、阻滞或截割，使奥氏体组织严重细化变为微晶甚至纳米晶，严重的点阵畸变使晶体的自由能升高，使之变成非晶态；纳米晶与非晶态的产生是高能量冲击载荷下，高锰钢加工硬化的一种机制，是优越耐磨性的一个重要的原因
Different impact energy, high wear-resistant manganese steel has different performance. Nanocrystalline and amorphous are the unique sub-structures of high-manganese steel under high-energy impact load. The high-density deformed strips cross each other, block or cut the austenite microstructure into serious crystallites and even nanocrystals, A serious lattice distortion makes the free energy of the crystal increases, making it into a non-crystalline; nanocrystalline and amorphous state is a high energy impact load, the high manganese steel work hardening is a mechanism that is superior wear An important reason for sex
