MODIFIED HIGH SPEED STEEL PARTICLE, POWDER METALLURGY METHOD USING THE SAME, AND SINTERED PART OBTAINED THEREFROM
Particles made from a High Speed Steel (HSS) that is modified to contain dispersed precipitations of manganese sulfide (MHSS), a Powder Metallurgy (PM) method using the same, and a part produced by the PM process using the modified HSS particles. By forming a melt of a HSS and 1) Mn or a Mn-containi...

| description | Particles made from a High Speed Steel (HSS) that is modified to contain dispersed precipitations of manganese sulfide (MHSS), a Powder Metallurgy (PM) method using the same, and a part produced by the PM process using the modified HSS particles. By forming a melt of a HSS and 1) Mn or a Mn-containing compound and 2) S or an S-containing compound, followed by an atomization process, modified HSS particle can be obtained containing dispersed sulfide precipitations containing mainly manganese sulfide. The amount of Mn and S are chosen such that the weight ratio of Mn to S (Mn/S), in wt-% of the total weight of the particle, is in the range of 8.0-1.0. An article obtained by a PM manufacturing method using the particles has improved machinability as compared to a an article prepared from a corresponding non-modified HSS. |
