Hot work tool steels are specialized alloys designed to withstand extreme conditions during the hot-forming of metallic workpieces. These steels facilitate manufacturing processes such as pressure die casting, extrusion, and drop forging at elevated temperatures. Distinguished by their ability to maintain hardness and structural integrity despite thermal cycling, hot work tool steels require specific properties including high tempering resistance, thermal shock resistance, and wear resistance.
Iron Spark Plasma Sintering (SPS): Part Two
Spark Plasma Sintering (SPS) is a sintering technique which is well matched to mechanically milled materials such as tool steels due to its low temperature and short cycle time.One of the key objectives using SPS is to increase the density of the sinter in order to attain better overall property profiles of the finished part.
