Hot formability evaluated by the wedge rolling test

Popis výsledku v původním jazyce

The new methodology of determination of hot formability of metallic materials was developed, based on application of the wedge rolling test in laboratory conditions. It is suitable for quick evaluation of rollability and in co-operation with the following metallographic analyses for study of selected structure-forming processes as well. As steels are in hot state mostly so plastic that not even single height reductions above 70 % during the wedge rolling test lead to cracks, it is advisable to carry outin manufacturing of initial samples additional modifications enabling easier development of cracks. This modification consists in milling out the defined notches on a side wall of the sample. A series of wedge-shaped tests at different temperatures werecarried out in the laboratory rolling mill K350. The experiment was made with an austenitic Cr-Ni-Si steel. A special computer program was developed for determination of geometric dimensions of the rolled stock and calculation of its def
