Description	The paper contains results and discussion of experiments performed as a supplementary programme to the Research Centre project FORTECH, coordinated by the University of West Bohemia (UWB), Prof. Bohuslav Masek. Fatigue strength including fatigue limit of an experimental 42SICR steel after different heat treatment procedures was investigated. The 42SICR steel belongs to the group of materials suitable partucularly for manufacture of transport vehicles components like shafts, pins, screws or springs. The 42SICR steel ocntains an increased amount of Si with the aim to improve strength and fatigue resistance. The steel was treated by conventional heat treatment and by advanced quenching and partitioning (Q-P) processes, respectively, the latter having been developed in UWB. The Q-P process consists in quenching at intervals between martensite start and martensite finish temperatures and results in stabilisation of untransformed austenite by carbon diffusing from martensite. As a result, well balanced properties, i.e. strength about 2000 MPa and ductility more than 10-15%, can be achieved, unlike standard heat treatment resulting in high brittleness.
