摘要
Abstract
Different plastic deformation treatments and aging heat treatments were performed on 10CrNi3MoV low alloy structural steel,and tensile tests were conducted on the samples to study the influence of plastic deformation treatment and aging heat treatment on the tensile properties of the material.A relationship model between plastic deformation and tensile parameters of the material was established,and the fracture morphology of the samples was observed.The results show that as the plastic deformation rate increased,the yield strength and tensile strength of the material gradually increased,while the elongation after fracture and maximum total force elongation gradually decreased.The crack size generated in the fiber zone first increased and then decreased.The fracture form of the specimens after different plastic deformation treatments was ductile fracture.With the increased of aging temperature,the yield strength and tensile strength of the material showed a trend of first increasing and then decreasing,and the maximum force total elongation continue to increase.A relationship model between plastic deformation and tensile parameters of materials was established,which could be used to predict the tensile properties of materials after different plastic deformations.关键词
