Identification of the curve of work-hardening of material on hardness and dura-bility

Abstract

The paper offers methods of construction of hardening curve on the basis of standard mechanical descriptions of material by Brinnel hardness method in combination with data of tensile and fluidity strengths at tension. Approximation of hardening curve is accepted as a power law of P. Ludwig. Nomographs are set up, the feature of methods and their exactness are demonstrated on the example with 8 different materials.
