Abstract (en)

[origin: GB2318126A] A powder mixture suitable for use in a compaction and sintering process comprises three constituents. The first constituent is substantially carbon-free and is formed by one or more alloyed powders and has a composition lying in the range expressed in % by weight: 8 to 12 chromium, 0.5 to 3 molybdenum, optionally up to a total of 10 of at least one metal selected from vanadium, cobalt and tungsten, a maximum of 2 of other materials including impurities, and the balance iron. The second constituent is formed by sufficient carbon powder to bring the total carbon content of the mixture to 1.5 to 3.0% by weight. The third constituent is formed by sufficient ferrophosphorus powder to bring the total phosphorus content of the mixture to 0.1 to 0.5% by weight.
