| 1 | PHASE STRUCTURE FACTOR AND INTERFACE CONJUNCTION FACTOR OF CAST IRON AND ITS COMPOSITION DESIGN显示文摘Theempiricalelectrontheory of solidsand molecules( EET) and theimproved TFDtheory wereapplied tocalculatethe phasestructurefactorsand interfaceconjunction factorsofcom mon alloying elementsincastiron. Akind of Si- Mo- Cu ductileiron with rareearth Mg asnodularizer was designed accordingtothese valenceelectron structure parameters. Actual applicationtestsshow thatthelongevity of thisiron is 1.5 timesof thatof high manganesesteel. This accordance of theoretical results and actual effectsshows the composition design methodcan beused in othercastiron research. | Z.L.Li,Z.L.Liu ,F.Y.Li,X.P.Yang and Z.G.Gu Departmentof Materials Science and Engineering ,Liaoning Institute of Technology,Jinzhou 121001 ,China | 1999 | Acta Metallurgica Sinica(English Letters)1999，12，4： | 3 |
