This paper deals with the formation,morphology and amount of inclusions in the commercial steel 20CrMnTi in which 0.1% RE compound are added together with 0.05% S,especially,to study the free-cutting behavior and mechanism caused by adding RE.Such apparatus as EPMA,SEM,QTM-720 quantitative image analyzer and X-ray diffractor are used for test.Experimental results give evidence that not only the significant improvement of machinability has been achieved by virtue of the compound inclusions containing RE (in the present work Ce is major) and S,but also the steel 20CrMnTiRS keeps firm in mechanical properties and technological performance as good as the reference steel 20CrMnTi,such as the transverse toughness,hardenability,potential of austenite grain growth and carburized structure etc.In respect to free-cutting mechanism,the contribution of RE added in 20CrMnTiRS to improving machinability is referred to as follows:(1) The so-called encasing effect comes from RE-S system compound inclusions leads the exceedingly hard Al2O3 particles to be encased so as to reduce their unfavourable factors to the least in machining;( 2 ) The other exceedingly hard particles as TiN and SiO2 are combined with RE to form Ce-S-O-Ti-Si system compound inclusions not so hard as they were in 20CrMnTi and their melting-point lowers,so the favourable machining conditions are obtained therefrom;(3) A protective film,comes also from RE-S system compound inclusions,is formed to coat the cutting surface of TiC carbide tool during cutting so as to isolate the diffusion of alloying elements between chips and cutting tool and to lublicate them in machining.As a result,the wear rate of cutting edge on carbide tool for cutting the steel 20CrMnTiRS is only 16% of that for cutting 20CrMnTi.Moreover,RE inclusions play an important role as a source of stress concentration in reducing cutting force,e.g.,a decrease in cutting force for cutting 20CrMnTiRS is 16.5 kg in comparison with cutting 20CrMnTi,

本文利用电子探针、扫描电镜,QTM-720自动图象分析仪及x-射线衍射等技术,较详细地研究了在复合加入RE和S的20CrMnTiRS钢中夹杂物的组成、形态与数量的变化及其在切削过程中的行为与作用。结果表明,复合稀土夹杂物的形成,不但能保证基础钢的机械性能与工艺性能不变,还能使钢的切削加工性获得明显改善。RE对该钢易切化机理的作用主要表现为在含TiC的硬质合金刀具表面上形成覆盖膜以及复合稀土夹杂物有“包裹作用”。
