Purpose: The aim of this paper is to determine the relation existing between the behaviour of the signals of acoustic emissions generated in the course of plastic deformation at elevated temperature, and the shape of the work-hardening curves σ-ε and the Portevin - Le Chatelier effect. Design/methodology/approach: Single crystal was investigated applying the method of free compression at a constant...
Purpose: The aim of research was to investigate the effect of heat treatment and low-temperature thermomechanical treatment (LTMT) on the structure and mechanical properties of Al-Mg-Mn alloys. Design/methodology/approach: The range of researches included: performance of heat treatment and low-temperature thermomechanical treatment of AlMg1.5 and AlMg3.5Mn alloys, carry out of static tensile tests,...
