摘　　要：将一种自主研发Al-Fe-Mn铝合金进行热轧和冷轧至2 mm,然后将轧板加热到340~400℃进行等温退火,通过比较不同退火温度和保温时间条件下的铝合金板的硬度变化,并结合金相组织检验,确定了该合金的定时条件下的再结晶温度以及恒温条件下的再结晶时间。通过Arrhenius公式计算了试验钢的再结晶激活能。试验结果表明,当退火温度为340℃时,再结晶发生时间为13 min;当退火温度提高360℃时,再结晶时间缩短到8 min;而当退火温度进一步提高到380℃,再结晶在3 min时发生。再结晶激活能Q为115.9 kJ/mol。A self-developed Al-Fe-Mn aluminum alloy sheet was hot-rolled and cold-rolled to 2 mm,and then isothermal annealing was carried out by heating the sheet to 340-400℃.By comparing the hardness variation of aluminum alloy sheets under different annealing temperatures and holding time conditions,and combining with metallographic examination,the temperature and time of recrystallization transition under certain holding time and constant temperature were determined.The recrystallization activation energy of the sheet was calculated through Arrhenius formula.The results have revealed that the recrystallization time is 13 minutes when the annealing temperature is 340℃,and the recrystallization time is reduced to 8 minutes when the temperature is increased to 360℃.The recrystallization occurs in 3 minutes when the temperature is further increased to 380℃.It is found that the calculated recrystallization activation energy is 115.9 kJ/mol.
