矫顽力在碳钢热处理质量预评定中的应用
Application of Coercivity Force in Pre-evaluation of Heat Treatment Quality
摘 要
常规的热处理质量评定方法需对材料进行破坏性加工，效率低下，且不适用于产品批量检验。针对这一缺点，提出基于矫顽力（Hc）的磁滞无损评估方法，研究了不同热处理条件下，碳钢显微组织及力学性能与矫顽力的关系。结果表明：碳钢3种典型显微组织对应不同的矫顽力水平，其顺序为Hc马氏体 > Hc珠光体 > Hc铁素体；常用力学性能指标与矫顽力近似成线性关系；通过测定矫顽力既可以快速辨别碳钢的显微组织，又能对力学性能实现定量预测，因此可用于其热处理质量的预评定。

Abstract
Conventional methods of heat treatment quality evaluation need destructive processing of materials, which were inefficient and unsuitable for products batch inspection. Then, a magnetic nondestructive evaluation method based on coercivity(Hc) was proposed, and the relationship between the microstructure, mechanical properties and coercivity force of carbon steel under different heat treatment conditions were studied. The results show that three typical microstructures of carbon steel corresponded to different coercivity force levels, the order of which was Hc (martensite) > Hc (pearlite) > Hc (ferrite). The common mechanical properties were approximately linear with coercivity force. Though measuring coercivity force could not only identify the microstructure of carbon steel quickly, but also predict the mechanical properties quantitatively, this could be used to pre-evaluate the carbon steel of heat treatment quality.
