The forecast of maximum stresses on compaction tools is frequently based on the so-called compressibility curves, obtained according to specific standards. The analysis of compressibility curves enables to draw a simple analytical law, to utilize for

The elastic and plastic properties of some ferrous base materials, before and after steam treatment, have been evaluated by means of a rather new testing method, named universal hardness testing. This test makes it possible to record continuously the

The hardenability of some PM steels designed for heat treatment has been evaluated on sintered steel specimens by applying the procedure standardised with the Jominy end quench test. The samples have been produced using two types of commercial powder

In some powder metallurgy part forming, when high compacting loads would require a too large single shrink fitted die, or the inner die diameter is very large but the compaction area is modest, twice shrink fitted dies, which are relatively expensive

Four grades of sinter hardening materials have been compared, using industrial equipment. Three powder types were completely prealloyed; the last one was a hybrid, combining prealloying and diffusion bonding. Different amounts of Cu have been added b

The behaviour of a sintered alloy Fe Mo 1.5 C 0.01 in two density states when subjected to an ion nitriding process is analysed. The thermochemical treatment was carried out with three different combinations of parameters (time, nitriding atmosphere)

The influences of carbon on microstructures and properties of wrought steels are discussed. The basic metallurgical knowledge has showed for a long time that the optimum properties depending on alloy additions can be achieved only by a correct contro
