Abstract
Destruction of the thermally reinforced steel St3sp is considered at monaxonic tension. Influence of corner of meeting of crack is investigational with the border of division of areas in a metal with a different microstructure. It is shown that at crack movement from structure of less strong in stronger at meeting corners from 0 to the 45°th crack changes the direction and extends on limit of the section. At the further increase of corner of meeting a crack crosses a border and spreads practically on a former trajectory. The maximal rejection of crack on the border of division of two structures is arrived at coal 45°.
