1Inconel 617 and Stellite 6 alloys for tooling in thixoforming of steels显示文摘Thermal fatigue and high temperature wear are the two principle failure mechanisms for thixoforming dies.Samples of Inconel 617 and Stellite 6 alloys were submitted to thermal cycling under conditions which approximate thixoforming of steels and to sliding wear tests at 750 °C.The experimental results thus obtained were compared with those of the X32CrMoV33 hot work tool steel.The Inconel 617 and Stellite 6 samples are much more resistant to oxidation and to softening than the hot work tool steel, providing a superior resistance to thermal fatigue cracking.The wear resistance of the Inconel 617 and Stellite 6 alloys at 750 °C is also markedly superior.The adhesive oxides growing slowly on Inconel 617 and Stellite 6 alloys sustain the wear action without spalling and are claimed to be responsible for the superior wear resistance of these alloys at 750 °C.Y.BI ROL 2010Transactions of Nonferrous Metals Society of China2010,20,9:18

4The characterization of Fe-rich phases in a high-pressure die cast hypoeutectic aluminum-silicon alloy显示文摘Both microstructural characteristics and fracture behavior of Fe-rich phases in a high-pressure die-cast hypoeutectic Al-Si alloy were investigated.Attention was focused on the morphology and formation mechanism of Fe-rich phases,together with their influence on fracture.Results show that primary Ferich phases exhibited in blocky shape precipitated from liquid while secondary Fe-rich phase in a large net shape was distributed along eutectic boundary participating in a ternary eutectic reaction.Through synchrotron X-ray tomography characterization,three Fe-rich phases with different morphologies,i.e.,polyhedral shape,fine compact shape and Chinese script-type shape were extracted along the radial direction.Lower slow-shot speed promoted the polyhedral Fe-rich phase to precipitate in slow-shot sleeve while decreased the formation of fine compact and Chinese script-type Fe-rich phases in die cavity.Because of a worse deformation compatibility,polyhedral Fe-rich phases fractured and became stress concentration sources before the failure of the casting.X.Y.Jiao C.F.Liu Z.P.Guo G.D.Tong S.L.Ma Y.Bi Y.F.Zhang S.M.Xiong 2020Journal of Materials Science & Technology2020,47,16:1
