研究了含 1 .7% C,1 .85 % Cr和 1 .78% Mn的半钢经 1 1 5 0℃～ 90 0℃锻造后 ,采用不同方式进行等温淬火处理 ,对半钢材料冲击韧性的影响 .结果表明 ,锻造等温淬工艺可以改善半钢材料的冲击韧性 ,从而达到了提高半钢冲击韧性的目的
After the semi-steel containing 1.7% C, 1.85% Cr and 1.78% Mn was forged at 115 ℃ ~ 90 ℃, the austenitizing process was carried out in different ways. The impact toughness The results show that forging isothermal quenching process can improve the impact toughness of semi-steel materials, so as to achieve the purpose of improving the impact toughness of semi-steel
