Aging Performance Study of U75V Rail
摘要 采用自然时效和人工时效方法,研究了温度、时间对性能、成分的影响。结果表明:随着时间增加及温度升高,U75V钢轨存在强度提高而残余应力和氢含量下降的现象,具有一定时效性。
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.
