The rolling process of closed-cell aluminum foam that was prepared by melt-foaming process was studied,as well as its deformation and failure behavior due to different pass reduction.
研究了采用熔体发泡法制备的闭孔泡沫铝材料的轧制过程,分析了不同道次压下量条件下泡沫铝的变形特点与破坏方式,探讨了影响泡沫铝轧制能力的主要因素。
Pass reduction has effect on the bonding strength,and after the pass reduction reaches some value the bonding strength degrades with increasing pass reduction.
结果表明:当轧制温度为1000～1100℃时,25Cr5MoA钢/微合金钢/Q235钢能有效复合;压下量对25Cr5MoA钢/Q235钢复合板界面结合强度有一定的影响,当压下量达到一定程度后,随着压下量的增加,复合板的结合强度逐渐降低;轧制温度对25Cr5MoA钢/微合金钢/Q235钢复合板界面结合强度影响很大,在道次压下量一定的情况下,随着轧制温度的升高,复合板的结合强度逐渐升高。
