The secondary hardening phenomenon in strain-hardened MP35N alloy
Acta Materialia, 1998Abstract Mechanical testing and microscopy techniques were used to investigate the influence of aging on the structure and strengthening of MP35N alloy. It was confirmed that aging the deformed material at 600°C for 4 h provided additional strengthening, here referred to as “secondary hardening”, in addition to the primary strain hardening.

Introduction With elastic deformation, the strains are proportional to the stress, so every level of stress causes some elastic deformation. On the other hand, a definite level of stress must be applied before any plastic deformation occurs. As the stress is further increased, the amount of deformation increases, but not linearly.

The quasi-static mechanical response of high purity, polycrystalline [alpha]-titanium is investigated in terms of the underlying deformation mechanisms that govern its macroscopic behavior at room temperature. Constant strain rate tests were conducted on this material in simple compression, plane-strain compression and simple shear, and the true stress

Strain Hardening and Annealing
1996In this chapter we will discuss three main topics: cold working, by which a metal is simultaneously deformed and strengthened; hot working, by which a metal is deformed at high temperatures without strengthening; and annealing, during which the effects of strengthening caused by cold working are eliminated or modified by heat treatment.

The Effect of Strain Hardening in an Annular Slab
Journal of Applied Mechanics, 1953Abstract A procedure is outlined for obtaining the stresses and strains in a circular slab with a cutout, subject to uniform biaxial tension. An arbitrary stress-strain curve in tension is approximated by any number of straight-line segments.

Shock Propagation in a Strain-Hardening Material
Journal of Applied Mechanics, 1969Weak shock theory is used to analyze the propagation of the stress waves which are induced by nonuniform, instantaneous, internal heating of a nonlinearly elastic, semi-infinite solid. The material nonlinearity considered is caused by the increase in bulk modulus which occurs as the hydrodynamic stress component increases.
