Abstract

The present work summarizes the results obtained by compacting water atomized powders of T42 modified carbon and vanadium, M3/2 and M2 high speed steels. The powders were compacted under complex forms (cut off dies) and sintered under a 90 N₂-9 H₂-I CH₄ industrial atmosphere. Heat treatments in different severity media were performed. Hardness of 1,100 HV can be obtained in the case of T42 modified steel. Also, the shrinking of the sintered specimens was study.
