Grain Bending at Deformation of the Steel and Arrangement of Internal Stresses

Abstract:

Arrangement of Internal Stresses in Deformed Austenitic Steel is Studied. the Internal Stresses are Determined Using Parameters of Bending Extinction Contours Observing on Electron Microscope Images of the Steel. at the Deformation Degree ε = 14% the Average Internal Stress Values inside Separate Grains with Complex Bending is much Greater than <σ> in a Grain with Simple Bending. the Difference of <σ> at the Deformation Degree ε = 25% in Grains with Simple and Complex Bending is Small. this is Explained by Considerable Relaxation of the Internal Stresses in the Deformed Steel Caused by Appearance at ε > 20% of a Great Number of Microtwin Packages
