Hardening curves for materials with strain hardening
Russian Engineering Research, 2016Experimental hardening curves are plotted for the analysis of the cutting process in strain-hardening materials. As examples, approximate formulas for specific carbon steels are presented.

Kinematic hardening model considering directional hardening response
International Journal of Plasticity, 2018Abstract This paper proposes a kinematic hardening model to capture both asymmetric plastic behavior (early-reyielding, transient Bauschinger effect and permanent softening) and directional hardening (anisotropic hardening) response at the same time.

A model comprising work hardening and solid solution hardening
Physica Status Solidi (a), 1978In a former paper the problem of solid solution hardening and work hardening of solid solutions was treated for the case of two types of obstacles with relative concentrations xs and xw, and strengths ƒs and ƒw. The resolved shear stress can be formally written as τ2/(Gb/l0)2 = τ(ƒs, ƒw, xs, xw) where G and b have their usual meaning and l0 denotes ...

Work hardening of dispersion-hardened crystals
Philosophical Magazine, 1966Abstract A new theory of work hardening in dispersion-hardened single crystals—by which we mean soft crystals containing hard non-deforming particles of a second phase—is described. It is based on the fact that, if the particles do not deform plastically, and the interface between particle and matrix does not fracture, then secondary slip must occur ...

Steels with controlled hardenability for induction hardening
Metal Science and Heat Treatment, 1980Steels of the CH and LH type developed in the Soviet Union permit the use of a new method of induction hardening — bulk-surface hardening — and efficient utilization of the high-strength conditions (σb = 230–250 kgf/mm2). These steels make it possible to improve the structural strength, operating characteristics, service life, and reliability of ...

Strain Hardening and ‘Strain-Rate Hardening’
1982The limitations of power-law strain hardening and ‘strain-rate hardening’ descriptions are reviewed. It is found that significant advantages can be gained by using, instead, the Voce relation, especially in the proposed modification that accounts for the rate sensitivities of flow stress and of strain hardening.

Abstract Inverse hardening a steel of adequate hardenability requires a workpiece of sufficiently large cross section, an appropriate cooling medium, and the right quenching conditions. This article explains the Temperature Gradient Quenching Analysis System (TGQAS), which can measure, record, and evaluate all quenching processes in ...
