Plastic properties of cold-deformed ironbased sintered materials
Journal Title: Archiwum Odlewnictwa - Year 2010, Vol 10, Issue 3
Abstract
Cold plastic forming of sintered metal powders has limited practical application because of, among others, the deformation degree and initial porosity of preforms. Cold forming is combined with a very drastic drop of plastic properties observed in final products. One of the methods that enable regaining the lost plasticity is annealing of sinters after deformation at temperatures above the recrystallisation point. The results of the investigations were presented which aimed at the determination of an effect that the annealing conditions of colddeformed sintered metal powder can have on its structure and mechanical properties. Special attention was drawn to a combined effect of the deformation degree and heat treatment temperature on final plastic properties of the sinters and on their ultimate tensile strength.
