Conclusions
-
1.
The addition of iron powder to ground cast-iron swarf widens the sintering temperature range of components.
-
2.
The addition of up to 30% of ground cast-iron swarf to an iron-powder charge enables dense materials (of 0–4% porosity) to be produced exhibiting high mechanical properties.
-
3.
A substantial increase in the hardness and mechanical properties of sintered parts produced from a mixture of castiron and iron powders can be obtained by additionally alloying the charge with 0.1–0.4% each of graphite and manganese.
