Deformation behaviour of surface layers of continuously cast blanks from C-Mn-Cr steel

Popis výsledku v původním jazyce

Due to heterogeneity of structure and to casting defects contained in surface layers of continuously cast blanks with large cross sections the study of their deformation behaviour, and namely of their hot formability is a highly demanding task. Exact plastometric methods in the case of taking of the samples from surface areas do not provide acceptable results, since due to their small sizes they cannot express sufficiently the present structure heterogeneity. Surface layers of material, in which it is possible to expect the biggest occurrence of defects that expand at the subsequent forming till they achieve character of critical cracks, are then removed from the samples by machining. For these reasons the wedge rolling test, performed in partly non-machined samples, proved to be successful for investigation of these continuously cast blanks. One of the freely spreading side surfaces of the sample corresponds to the raw surface of the casting and it is then possible to use it then from
