摘要：

为了研究锻造温度对M2-1.6Si高速钢组织及冲击性能的影响，采用不同的锻造温度进行了锻造试验，并进行了组织和冲击性能的测试与分析。结果表明：始锻温度从1130 ℃增至1210 ℃或随终锻温度从790 ℃增至870 ℃时，试样内部碳化物先细化后粗化，冲击性能先提高后下降。在其他工艺参数不变的情况下，始锻温度为1130 ℃时，试样内部碳化物呈粗大“骨头状”形态；始锻温度为1170 ℃时，试样内部碳化物呈细小颗粒状，冲击韧性较始锻温度为1130 ℃时增大了33.7%。当其他工艺参数不变时，终锻温度为790 ℃时，试样内部碳化物呈现出大小不一的“骨头状”形态；终锻温度为830 ℃时，试样内部碳化物呈细小颗粒状，冲击韧性较终锻温度为790℃时增大了21.7%。

In order to study the influences of forging temperature on the microstructure and impact property for M2-1.6Si high speed steel, the forging tests were carried out at different forging temperatures, and the microstructure and impact property were tested and analyzed. The results show that when the initial forging temperature increases from 1130 ℃ to 1210 ℃ or the final forging temperature increases from 790 ℃ to 870 ℃, the carbides in the sample are refined first and then coarsened, and the impact properties are improved first and then decreased. Under the condition that the other process parameters remain unchanged, when the initial forging temperature is 1130 ℃, the carbides inside the sample are in the form of coarse “bone-like” shape, while the initial forging temperature is 1170 ℃, the carbides inside the sample are fine particles, and the impact toughness increases by 33.7% compared with that at the initial forging temperature of 1130 ℃. When the other process parameters remain unchanged and the final forging temperature is 790 ℃, the carbides inside the sample present a “bone-like” shape with different sizes, while the final forging temperature is 830 ℃, the carbides inside the sample are fine particles, and the impact toughness increases by 21.7% compared with that at the final forging temperature of 790 ℃.
