Microstructure and Properties of Advanced Tool Steels

Original language description

In this work, the microstructure and mechanical properties of four types of high-speed tool steels (Vanadis 30, Vanadis 60, ASP 2052 and S 705) were studied. The steel S 705 was made by conventional ingot metallurgy technology, and other types of steels were manufactured by powder metallurgy technology. All studied steels were examined both in the soft state and further in the hardened condition with subsequent tempering. Microstructure of metallographic samples and fracture areas was studied by electron microscopy. Hardness, tensile properties and notch toughness were determined. Significant differences in the properties of steels in both studied states were documented. The microstructure of high-speed steels produced by powder metallurgy (Vanadis 30, Vanadis 60 and ASP2052) was relatively uniform, whereas in the case of the steel produced by the ingot metallurgy (S 705), coarse carbide particles were observed to disturb its uniformity. Two types of carbide phase (VC carbides and mixed carbides containing W and Mo) were observed. Vanadis 60 had the highest Rockwell hardness and the S 705 has the lowest Rockwell hardness in both soft-annealed and hardened + tempered condition. Vanadis 60 steel had also the highest yield and tensile strength of all studied high-speed steels. The notch toughness of all steels in softannealed state had approximately a double value compared to steels in hardened + tempered state.
