Analysis of the effect of cold plastic deformation and subsequent heating on the properties of metal

Abstract

Metal is used in many branches of domestic industry, so increasing its strength becomes an urgent topic for the development of various industries where metal is an integral element. An effective way to increase the strength of the metal is cold plastic deformation and heating. This article presents the experience of studying the influence of cold plastic deformation and heating on the properties of metal. With the help of a rivet, the hardness and ultimate strength can be increased by 1.5-3 times, and the yield strength by 3-7 times. The greater the degree of deformation, the stronger the coercive force increases and the lower the magnetic permeability and density of the metal. The use of plastic deformation is an effective way to strengthen the finished metal product.
