摘要
微碳深冲钢板（０３Ａｌ），是国内为适应汽车工业发展的需要，开发研制的新一代深冲钢板。在试制生产中发现有时屈服强度σｓ 偏高，ｎ 值偏低，游离渗碳体析出超标等现象。针对在实际生产中出现的问题，在实验室中对试样进行不同的退火温度（６００～７５０ ℃）和不同压下量的平整（０．４ ％ ～２．４ ％ ）试验，对组织和力学性能进行观察和测量，分析各种工艺参数对渗碳体析出、晶粒尺寸和性能的影响。结果表明：６８０～７１０ ℃退火和０．９ ％ ～１．２ ％ 的平整量是保证性能的关键因素之一。
The low carbon steel introduced in this paper is a new deep drawing steel developed for automobile The influence of annealing and temper rolling on formability of the deep drawing steel sheet is discussed in the paper The influence of annealing processing on ferrite grain size,free cementite and elongation has been investigated The relation between temper rolling reduction and yield strength and work hardening index n value has been studied,and the suitable processing parameters for the new deep drawing steel have been obtained
