Web11 Apr 2024 · Tensile testing or Tensile Test is also known as Tension Test is a Destructive Test method and the most common type of mechanical test. A tensile test is used to determine the yield point or yield strength, tensile strength or ultimate tensile stress, and percentage elongation of a metal.

Web6 Jul 2024 · Abstract. In this paper, the tensile flow and work hardening behaviour of Beta titanium alloy was examined over a wide temperature range of 28 to 500°C. The work hardening of the material was modelled using different empirical relations such as Swift, Voce and Ludwigsen and the prediction accuracy of these models were compared with … WebAs a result, the flow stress is increased, and the dislocation storage is promoted at the same time, which increases the strain hardening and hence the ductility. Meanwhile, the segment detrapping along the dislocation line entails a small activation volume and hence an increased strain-rate sensitivity, which also stabilizes the tensile flow.
