对亚温淬火后的中碳低合金钢进行了多向锻造及退火处理,研究了试样的二体磨料磨损性能。结果表明:与传统热处理调质状态和正火状态相比,多向锻造及退火处理改善了材料的抗拉强度和显微硬度;在硬磨料工况下,多向锻造及退火处理使材料的耐磨性有较大幅度提高,磨损机制仍然以微切削为主。
After mild quenching medium temperature carbon steel low alloy steel forging and annealing treatment, the two-body abrasive wear properties of the sample. The results show that the multi-direction forging and annealing improve the tensile strength and the microhardness of the material compared with the state of the quenched and tempered state and the normalized state of the heat treatment. In the condition of hard abrasive, the multi-direction forging and annealing make the material resistant Grinding a more substantial increase, the wear mechanism is still based on micro-cutting.
