    摘要:

    用Ｆｅ、Ｎｉ部分取代ＷＣ－８Ｃｏ合金（牌號(hào)ＹＧ８）中的粘結(jié)劑Ｃｏ，再添加微量稀土Ｒ制得ＷＣ－８（Ｆｅ／Ｎｉ／Ｃｏ）Ｒ硬質(zhì)合金，測(cè)試了其物理機(jī)械性能，研究了粘結(jié)劑各種成份比例及燒結(jié)溫度對(duì)硬質(zhì)合金的影響。結(jié)果表明：ＷＣ－８（Ｆｅ／Ｎｉ／Ｃｏ）Ｒ硬質(zhì)合金的性能可以達(dá)到ＹＧ８的性能標(biāo)準(zhǔn)。利用掃描電鏡（ＳＥＭ）及Ｘ射線衍射（ＸＲＤ）對(duì)其作了顯微結(jié)構(gòu)分析，同時(shí)探討了影響ＷＣ－８（Ｆｅ／Ｎｉ／Ｃｏ）Ｒ合金性能的

    Abstract:

    Cemented carbides of the type WC 8(Fe/Ni/Co) R were made by means of adding minor rare earth elements( R ) and a Fe Ni binder (partly substiting for the Co binder) and their physical and mechanical properties were tested. The influences of various compositions and sintering temperatures on the properties of the alloys have been studied. The results indicate that the properties of the WC 8(Fe/Ni/Co) R cemented carbides are comparable to those of the WC 8Co alloys. The microstructures of the alloys were studied using scanning election microscopy (SEM) and X ray diffraction. Some factors that influence the properties of the WC 8(Fe/Ni/Co) R alloys are discussed in detail.
