Structural Aspects of Zones of Plastic Strain. Part I. Effect of Adiabatic Shear

  • Published:
Metal Science and Heat Treatment Aims and scope

The structure, the dynamic crack resistance, and the characteristics of mechanical properties of quenched and tempered structural steel 09G2S are studied. Special features of structure in the zones of plastic strain (ZPS) under fracture surfaces are considered after a single dynamic test. The structural features of bands of adiabatic shear formed in the starting region of the zone of plastic strain and in the region of the force action of the hammer are studied. The influence of formation of bands of adiabatic shear on the level of dynamic crack resistance is assessed. The temperatures arising in the material in the process of three-point dynamic bending are calculated.
