钢结构

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.

结果示：控制热轧条件可以改进&钢三&的显微结构，从而改善了&钢三&机械时效处理后的变脆倾向，其中镇静钢的显微结构和晶粒度可以在较大的范围内改变而成品均可以达到标准的要求，但沸腾钢则要严格地控制其显微结构和晶粒度才能合格。
