✦ Synopsis


The work hardening coefficients of Type 316 stainless steel niobium, and 1100 aluminum alloy are measured in tensile tests. It is demonstrated experimentally that in the measured stress, plastic strain rate, and temperature range the work hardening coefficient depends only on the stress and plastic strain rate. The significance of the experimental results is discussed in terms of the concept of the mechanical equation of state for plastic deformation. R&m&On a mesuri par des e&s de traction les coefficients d'kcrouissage d'un acier inonydable de type 316, du niobium et d'un alliage d'aluminium 1100. On demontre exp&imentalement que, dans les domaines de contraintes, de vitesses de dkformation et tem@atures ttudies, le coefficient d'&crouissage ne dtpend que de la contrainte et de la vitesse de diformation plastique. On exprime les resultats exptrimentaux sous forms d'une iquation mkanique d'ttat pour la diformation plastique.

Stress relaxation experiments in monotonic loading have been performed on niobium and z-iron of two purity levels. The stress-strain rate relationship obtained at constant structures suggests that these metals exhibit the behavior of mechanical equation of state in the absence of discontinuous flow.
