织构形成的过程对低碳钢深冲性能的影响尚未作大量的研究。文献〔1～7〕均在670～800℃范围退火后研究了低碳钢的织构形成和性能。但迄今还没有在较大的退火温度范围互相联系地探讨织构形成过程和机械性能的变化关系。本课题就低碳沸腾钢在100～1200℃的区间内退火以研究深冲时的织构形成和机械性能的变化。作为研究深冲性能的低碳沸腾钢的试料成分为0.07％C,0.36％ Mn,0.018％Si,0.022％S,0.009％P,0.025％Cr,0.05％Ni,0.13％Cu,0.004％N。热轧的终轧温度为860℃,板
The effect of texture formation on deep drawing properties of mild steel has not been studied extensively. The text [1 ~ 7] were annealed in the range of 670 ~ 800 ℃ after studying the texture formation and properties of mild steel. However, up to now, the relationship between the texture formation process and the mechanical properties has not yet been explored in the larger annealing temperature range. The subject of low carbon boiling steel in the range of 100 ~ 1200 ℃ annealing to study the deep drawing of the texture formation and mechanical properties change. The compositions of the low-carbon steel with a deep drawability of 0.07% C, 0.36% Mn, 0.018% Si, 0.022% S, 0.009% P, 0.025% Cr, 0.05% Ni, 0.13% Cu and 0.004% N . Hot rolling finishing temperature of 860 ℃, the plate
