چکیده انگلیسی
The orientation relationship (OR) between α-Al(Mn,Fe)Si dispersoids and the Al matrix in AA 3003 alloy has been systematically studied by selected area electron diffraction patterns. New types of ORs between the cubic dispersoids and the cubic matrix phase have been found as ã1 â1 1ãp//ã1 â1 1ãm and {5 â2 â7}p//{0 1 1}m. High-resolution transmission electron microscopy and crystal structure simulation studies on the habit planes of dispersoids show that α-Al(Mn,Fe)Si dispersoids are partially coherent with the Al matrix. Precipitation of α-Al(Mn,Fe)Si dispersoids in the alloy has been found to have a strong influence on enhancing both the yield strength and tensile strength of the alloy. The dispersion-hardening effect of the dispersoids has been explained by the Orowan mechanism.
