In order to find out the effects of strainingand aging, impact, tensile, compression and hardness tests have been employed. The results show that it is possible to improve the properties of low carbonsteel against straining and aging by controlling the hot working conditions andthat the grain size and microstructure of killed steel may vary within fairly widelimits and yet its impact values after strain-aging may still remain within the re-quired standard; whereas strict control of the grain size and microstructure is ne-cessary in order to produce rimming steel of required impact value after strain-aging. It has been found that the impact and tensile test results show more promi-nently the effects of straining and aging; while the compression and hardness testresults are less consistent and do not yield so clear an information. Straining and aging is the combined effect of cold working and aging. Thecontribution of each of these two factors to the total effect of strain-aging varieswith the microstructure of steel. 收稿日期: 1957-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张作梅 李建华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1957/V2/I3/249 [1] Д.
