By changing heating temperature and holding time, the austenite grain growth behavior of a low carbon steel under different heating conditions was studied.
The effects of the aging temperature and holding time on the microstructure and hardness of the ultra-low-carbon steel bearing copper were investigated.
研究了时效温度和保温时间对时效硬化型超低碳含铜钢的显微组织和硬度的影响。
