Fatigue Properties of a Low Alloy 42SiCr Steel Heat Treated by Quenching and Partitioning Process

Popis výsledku v původním jazyce

In connection with increasing needs of different branches of industry for steels with excellent mechanical properties, like high strength combined with high ductility on one hand and low or at least moderate costs on the other hand, an experimental low alloy 42SiCr steel has been developed. If a conventional heat treatment is applied to this material, a very high strength can be reached, however with an unacceptable low ductility. Well balanced properties, i.e. strength about 2000 MPa and ductility morethan 10-15 %, can be achieved by an application of advanced heat treatment methods like Q-P (quenching and partitioning) process, consisting in quenching at intervals between martensite start and martensite finish temperatures resulting in stabilizationof untransformed austenite by partitioning carbon. In service, numerous engineering components are exposed to variable, fatigue loading, whereas resistance to fatigue is usually particularly affected by different heat treatment methods o
