Abstract

Effects of temperature and time on the performance and chemical composition fluctuation are studied with natural aging and artificial aging method. The results showed that the phenomenon of strength increased but residual stress and hydrogen content reduced is occurred with the increased time and temperature increased on U75V, and then timeliness.
