摘要: Phase relations in the dry condensed Fe-Ir-S system were determined at 1100, 1000 and 800 degrees C. Orientational runs performed 500 Between 1100 C, comprises five sulphides an uninterrupted field of gamma (Fe,Ir). Fe (sub 1-x) S dissolves 5.8 at.% Ir 3.4 C 1.0 The solubility 2 3 , IrS approximately 3) increases with decreasing temperature, reaching 2.5 latter two Thiospinel "FeIr 4 " is non-stoichiometric, from 22.3) 19.8) 58.0) to 18.9) 23.1) depending on a s i.e. phase association. absent
