The phase diagram for the common end members of the olivine solid solution series shows that pure forsterite melts at 1890 o C and pure fayalite melts at 1205 o C. Thus, the olivines are sometimes seen be be zoned from Mg-rich cores to more Fe-rich rims, although such zoning is usually limited to 5 to 10% difference between the cores and the rims.

Aug 01, 2013 · In the present Co–Cr–Fe–Mn–Ni alloys, no phase separation was observed, even though they were furnace-cooled from homogenization temperatures. This can be understood based on two reasons. First, in HEA, the high mixing entropy enhances the mutual solubility between elements and the stability of solution phases [76] .
