FIELD: measurement equipment.
SUBSTANCE: method for determining residual hardening stresses involves hardening of samples and determination of residual hardening stresses; at that, a pack is formed of plates of similar size, which are numbered and marked in advance; then, the above pack is subject to hardening; after that, plate bending deformations are measured in two planes, as per which residual hardening stresses are calculated.
EFFECT: improving accuracy of determination of residual hardening stresses.
