Abstract
AbstractIn the present investigation, the effect of varying sintering temperatures (1050–1200°C) on the mechanical properties of Fe–P–Mo powder compacts sintered for 45 min in a dry hydrogen atmosphere was studied. Molybdenum content in iron or phosphorus- containing iron was varied from 1 to 4 wt-% while phosphorus was in the range 0 to 0·6 wt-%. It was observed that with an increase in sintering temperature there was an increase in linear shrinkage and mechanical properties of all the alloy systems. However, the magnitude of increase in properties was greater in the case of P-containing Fe–Mo compacts than in plain Fe-Mo compacts. The results are discussed on the basis of diffusivity data for the various alloying elements and liquid-phase sintering modes. PM/0203
