Hardening curves for materials with strain hardening

Russian Engineering Research, 2016
Experimental 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.

Laser hardening of metallic materials

Strengthening Technologies and Coatings, 2020
The surface microstructure of metallic materials formed under the effect of laser radiation is characterized by high degree of nonequilibrium, has layered structure consisting of the main three zones formed from the fused material, the heat-affected zone and the tempering zone.

Kinematic hardening of granular materials

Ingenieur-Archiv, 1990
Some recently developed constitutive equations (yield function, loading criteria, flow rule) for kinematic hardening of granular materials are discussed and some relevant material dependent parameters are determined on the basis of test results.

Structural aspects of materials hardening

Journal of Nuclear Materials, 1996
Abstract Dispersion-strengthened (DS) and precipitation-hardened (PH) copper-based alloys are suggested to be used for energy-strained components in the ITER discharge chambers. But, the stability of their properties remains still uncertain. It is evident, that of critical importance here is the stability of the composition and the morphology of ...

Thermoelastic Constitutive Equations for Chemically Hardening Materials

Journal of Applied Mechanics, 1974
Thermoelastic constitutive equations are derived for a material undergoing solidification or hardening as the result of a chemical reaction. The derivation is based upon a two component model whose composition is determined by the degree of hardening, and makes use of strain-energy considerations.

Anisotropic Hardening of Initially Orthotropic Materials

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1979
AbstractA hardening model for an orthotropic material is proposed. The corresponding anisotropic parameters are the components of a fourth order tensor function of the plastic strain, entering a quadratic equation for the yield surface. Assuming polynomial dependence on the plastic strain, the most general form of a polynomial fourth order orthotropic ...

Strain-Hardening Topography of Elastic-Plastic Materials

Journal of Applied Mechanics, 1983
In the context of a purely mechanical rate-type theory of plasticity, a special set of constitutive equations is discussed. A method [1,2] of characterizing strain-hardening behavior is utilized to examine the different types of response that may be exhibited.

Dispersion-hardened platinum materials

Anti-Corrosion Manual, 1988
The Special Metal Products Business Area of Degussa AG, Frankfurt am Main, presented an overview of its range of dispersion-hardened platinum materials. These materials, which remain resistant to corrosion by aggressive media such as gases and salt or glass melts even at high temperatures and which are capable of withstanding high mechanical loads, are

Materials with Thermo-Diffusive Hardening

Advanced Materials Research, 2011
Hardening problems in thermoplastic materials are presented. The examples of thermo-diffusive hardening are analyzed. Theoretical considerations are recalled to determine the combined effects of thermoplasticity with thermo-diffusion term considering gradients in interstitial concentration, in solvent composition, in stress and in temperature.
