这种新提出的新型铸铁的化学成分为在0.7C–5W–5Mo–5V–10Cr–2.5Ti (wt%)中分别添加1.6wt% B和2.7wt% B。这项工作的目的是研究硼的含量对合金的结构状态和阶段元素分布对耐磨结构成分的形成影响。结果表明，当B含量为1.6wt%时，合金由三种共晶组成：(a) “M2(C,B)5+铁素体”具有“汉字”形貌 (89.8vol%)， (b) “M7(CB)3+奥氏体”具有“莲座”形貌，(c) “M3C+奥氏体”具有“莱氏体”形貌 (2.7vol%)。当硼含量为2.7wt%时，基体硬度由HRC 31提高到HRC 38.5。组织中出现了平均显微硬度为HV 2797的初生碳化物M2(C,B)5，体积分数为17.6vol%。共晶体(a)和(b，c)的体积分数分别降低到71.2vol%和3.9vol%。基体为“铁素体/奥氏体” (1.6wt% B) 和“铁素体/珠光体”(2.7wt% B)，两种铸铁均含有致密析出碳化物(Ti,M)C和碳硼化物(Ti,M)(C,В)，体积分数为7.3%–7.5%。基于能量色散X射线能谱，给出了元素相的分布和相应的相公式。
The novel cast irons of chemical composition (wt%) 0.7C–5W–5Mo–5V–10Cr–2.5Ti were invented with the additions of 1.6wt% B and 2.7wt% B. The aim of this work was to study the effect of boron on the structural state of the alloys and phase elemental distribution with respect to the formation of wear-resistant structural constituents. It was found that the alloy containing 1.6wt% B was composed of three eutectics: (a) “M2(C,B)5+ferrite” having a “Chinese Script” morphology (89.8vol%), (b) “M7(C,B)3+Austenite” having a “Rosette” morphology, and (c) “M3C+Austenite” having a “Ledeburite”-shaped morphology (2.7vol%). With 2.7wt% of boron content, the bulk hardness increased from HRC 31 to HRC 38.5. The primary carboborides M2(C,B)5 with average microhardness of HV 2797 appeared in the structure with a volume fraction of 17.6vol%. The volume fraction of eutectics (a) and (b, c) decreased to 71.2vol% and 3.9vol%, respectively. The matrix was “ferrite/austenite” for 1.6wt% B and “ferrite/pearlite” for 2.7wt% B. Both cast irons contained compact precipitates of carbide (Ti,M)C and carboboride (Ti,M)(C,В) with a volume fraction of 7.3%–7.5%. Based on the energy-dispersive X-ray spectroscopy, the elemental phase distributions and the appropriate phase formulas are presented in this work.
