Influence of Bainite Fraction on Improving Mechanical Properties of Quenched and Tem-pered High Silicon Steel

Popis výsledku v původním jazyce

Martensitic steels are characterized by high strength which, on the other hand, is offset by considerable brittleness. This drawback can be partly corrected by tempering, at the cost of reduced final strength. If steel is alloyed with a sufficient amount of silicon, an optimum heat treatment sequence can produce a mixed microstructure consisting of martensite and carbide-free bainite. In various microstructures of this composition with identical grain size, mechanical properties would be dictated predominantly by the fraction of bainite. This article deals with design-ing a heat treatment sequence for a low-alloy steel. It is part of a research into the impact of bainite fraction on mechanical properties of materials with martensitic-bainitic microstructure. At an appropriate ratio of martensite and bainite, a steel with 0.42 % C can exhibit strengths above 2200 MPa at A5mm elongation of more than 17 %.
