Abstract
The preliminary results of A36 steel spall experiment are presented. Special attention is given to the heat treating conditions
in the two-phase (ferrite and austenite) region and resulting microstructure after the spall loading condition. One of the
fundamental principles of any thermomechanical processing in the twophase region is'the simultaneous superposition of microstructure
evolution and mechanical behavior of particular phase. The degree of generated defects, cracks and phases, and phase transformation
is decisive for the final microstructure and the fracture resistance. Preliminary resutts show the banded structure still
exists after the spall test and, totally unexpected lack of the visible characteristic voids, cracks or shear instabilities
due to the tensile loading at the mid plane of the sample.
