摘要

摘要: 为研究碳化物的分布、种类与刀具锋利度之间的关系，分别对30Cr13材料刀具的淬火态和回火态进行了锋利度测试和显微组织表征。结果分析表明，经过300 ℃、30 min回火处理后的刀具，其初始锋利度下降了34.6%，累计切割厚度下降了26.4%。但回火态的刀具单次切割下损失的锋利度值更小，有更好的耐用性。其原因是回火后M23C6型碳化物大量析出，通过弥散强化增强了耐磨性，而淬火马氏体中的碳减少，硬度下降，刀具锋利度降低。

Abstract: In the current study, the sharpness test and microstructure characterization for the 30Cr13 cutter under the regime of quenching and tempering processes was performed to investigate the relationship between distribution and type of carbides and sharpness of cutting tools. After the tempering process (300 ℃, 30 min), the initial sharpness and cumulative thickness cuts of the cutter decrease by 34.6% and 26.4%, respectively. However, the tool under the state of tempering have a less loss of sharpness in single cutting and a better durability, and the following reasons should be considered for these results: (i) the increase of the M23C6 carbide precipitates after tempering enhances wear resistance of tools through dispersion strengthening and (ii) the reduction of carbon in the quenched martensite leads to lower hardness and sharpness of the cutter.
