Hot deformation behavior of Cu-11.7%Mn-1.3%Ni alloy
摘要
Abstract
The material used in the experiment is hot rolled Cu-11.7％Mn-1.3％Ni alloy,the hot compression deformation is 60％,the strain rates are 1.000,0.100,0.010,0.001 s-1,and the deformation temperatures are 300,500,570,640,700℃.The effects of deformation temperature and strain rate on the rheological behavior and Vickers hardness of Cu-11.7％Mn-1.3％Ni alloy were investigated.The results indicated that the grains exhibts noticeable compression deformation at deformation temperature of 500 and 570℃,and most of the grains are broken,which shows that the microstructure was obviously deformed.As the emperature rises to 640 and 700℃,the grains grow up gradually,the grain size is uniform,and a large number of annealing twins appear.The Vickers hardness of the Cu-11.7％Mn-1.3％Ni alloy decreases with the increase of temperature,while it increases with the increase of strain rates.When the strain rate is 1.000 s-1,the Vickers hardness of Cu-11.7％Mn-1.3％Ni alloy is the highest.关键词
