摘要:
为了改善Fe3Al-5Cr(原子百分比a/%)材料韧性和室温磨损性能,通过机械合金化和热压烧结相结合制备了Fe3Al 与Fe3Al-5Cr块状试样,对其分别进行两种不同热处理:加热至550 ℃和950 ℃均保温8 h后炉冷至室温; 采用VEGA·ⅡXMU扫描电子显微镜和XRD-6000岛津X射线衍射仪对其进行显微组织及物相组成分析,采用WD-404显微维氏硬度试验机进行维氏硬度测试,采用DDL300电子万能试验机和MMG-500高温真空三体磨损试验机对其进行压缩和磨损性能测试.研究结果表明:未经热处理的Fe3Al-5Cr相对于基体Fe3Al 晶粒更均匀细小,韧性增加,但压缩强度、显微硬度和磨损行为均有所降低; 热处理后其显微组织和性能均有改善,尤其经950 ℃热处理后Fe3Al-5Cr压缩强度提高23%和显微硬度提高4%,同时室温油润滑条件下,其摩擦系数和磨损率分别降低了82%和40%,此时磨损性能更佳,其磨损失效机制以显微切削为主,并伴随少量氧化磨损.
Abstract:
The study aims to improve toughness and room temperature wear properties of Fe3Al-5Cr.Fe3Al and Fe3Al-5Cr bulk samples were prepared by mechanical alloying and hot pressing sintering,and the samples were heated to 550 ℃ and 950 ℃ for 8h and then cooled to room temperature.Their microstructure and phase composition were analyzed with a VEGA·ⅡXMU scanning electron microscope and an XRD-6000 X ray diffractometer,their microhardness was tested by using a WD-404 microhardness tester,and their compress and wear properties were tested by using a DDL300 electronic universal testing machine and an MMG-500 high temperature vacuum three body wear testing machine.The results show that the crystalline grains of Fe3Al-5Cr without being heat-treated were more uniform and finer than those of Fe3Al matrix.Its toughness increased but there was a reduction in its compression strength,microhardness and wear behavior.After having been heat-treated,its microstructure and properties were improved.Especially after heat treatment at 950 ℃ its compression strength and microhardness increased by 21% and 4% respectively.In addition,its friction coefficient and wear rate decreased by 82% and 40% respectively under the condition of room temperature oil lubrication.Its failure mechanism of wear was mainly micro-cutting,with a little oxidation wear.
