摘要
对55%变形条件下冷轧复合4A60铝/08Al钢复合带材进行退火处理,研究退火温度对钢层再结晶行为和铝-钢界面结合强度的影响。结果表明,退火温度为600℃保温60 min,钢层发生完全再结晶;退火温度为400~600℃,保温60 min,铝-钢复合板界面结合强度达到最大值9 N/mm,当保温时间为60 min,温度高于610℃时,铝-钢界面处产生脆性化合物,结合强度急剧降低至2.7 N/mm。确定55%变形条件下铝-钢复合板最佳退火工艺为600℃保温60 min。
4A60( Al) /08Al( steel) clad strips bonded by cold rolling were annealed after 55% reduction. The effect of annealing temperature on the steel recrystallization behavior and bonding strength at Al-steel interface was investigated. The results show that the steel recrystallized completely by annealing at 600 ℃ for 60 min. When the annealing temperature is 400-600 ℃ and holding for 60 min,the bonding strength at the Al-steel interface reaches maximum. 9 N / mm. However,when the holding time remains 60 min,and the annealing temperature exceeds 610 ℃,the intermetallic compounds appear at the Al-steel interface,and the bonding strength decreases from 9 N / mm to 2. 7 N / mm rapidly. The optimum annealing process of Al-steel clad strips is to anneal at 600 ℃ for 60 min with 55% reduction.
