EFFECT OF ALUMINIUM,CHROMIUM AND SILICON ON THE LATTICE PARAMETER FOR Fe-Mn-C AUSTENITE
Al,Cr,Si对Fe-Mn-C奥氏体点阵参数的影响

The lattice parameter of Fe-Mn-C austenite dissolved aluminium,chro-mium and silicon has been measured by means of X-ray diffractometer.The experimentalresults indicate that lattice parameter of Fe-Mn-C austenite increases linealy with an in-crease in aluminium or chromium content,while decreases linearly with an increase insilicon content.
