HOT DUCTILITY OF TWO HIGH MANGANESE STEELS

Popis výsledku v původním jazyce

The subject of this investigation was ductility (expressed as reduction of area) of two TRIPLEX type steels, 1043 and 1045, both at standard temperature, and in the temperature range 600°C to 1,100°C. Stacking fault energy of 1043 steel corresponded to 83 mJ.m-2 and that of 1045 steel to 95 mJ.m-2. In the 1043 steel ingot central area, higher inhomogeneity degree in the form of shrinkage porosity was detected than in 1045 steel. At standard temperature, 1043 heat with 25.8 wt. % Mn featured higher strength values by 66 MPa than 1045 heat with 21.6 wt. % Mn. Average microhardness was also higher by 8HV0.2 for 1045 steel than for 1043 steel (203HV0.2). Ductility level of the both heats at 20°C differed only by 3 % for the benefit of 1043 heat. At highertemperatures, i.e. 600 up to 1,100°C, a decrease in tensile properties which were practically coincident for both of the heats occurred. Strength level difference of the both heats in the temperature range 20°C to 1,100°C corresponded to
