摘要

如今,复合材料板材由于具有更好的耐腐蚀性和耐磨性,以及更高的强度和可成形性,在各种应用领域得到了越来越广泛的发展。其中,铝/不锈钢双层板因其良好的性能和低廉的成本已被用于食品和汽车行业。本研究通过实验研究了冷轧辊粘合法制造的 Al1050/AISI304 双层板材的粘合强度。首先,采用表面响应法进行了实验设计,考虑了层厚度和轧制减薄率,双层板采用了轧制粘接法。本研究首次对冷轧粘接法制造的铝/不锈钢双层板的粘接强度及其优化进行了研究。采用 T 型剥离试验提取粘接强度。然后,利用线性回归方法,提出了一种数学-实验关系,以获得层厚度和减薄率方面的剥离强度。利用统计方法对所得结果进行了分析,列出了与粘合强度相关数据的系数表、残差表和方差分析表,并检验了所提出模型的适当性。结果表明,通过降低冷轧过程中的还原率以及减少板材的初始厚度,双层板的结合强度降低了。然后,根据输入参数的函数对结合强度进行了优化。结果表明,在铝层厚度 = 2 毫米、不锈钢层厚度 = 1.3 毫米和减薄率 = 75% 时,结合强度达到最大值。

Bond strength empirical-mathematical equation and optimization of Al1050/AISI304 bilayer sheets fabricated by cold roll bonding method
Nowadays, composite sheets have been increasingly developed in various applications due to their better corrosion and wear resistance as well as higher strength and formability. Of these, Al/SS bilayer sheets have been used in the food and automotive industries due to their favorable performance and low cost. In this research, the bonding strength of Al1050/AISI304 bilayer sheets fabricated by cold roll bonding has been investigated experimentally. At first, the design of the experiment was carried out using the surface response method, taking into account the thickness of the layers and the rolling reduction ratio, bilayer sheet using the rolling bonding method. In this research, for the first time, the bonding strength of Al/SS bilayer sheets fabricated by cold rolling bonding method and its optimization have been investigated. The bond strength was extracted using T peeling test. Then, using the linear regression method, a mathematical-experimental relationship was presented to obtain the peeling strength in terms of the thickness of the layers and the reduction ratio. The obtained results were analyzed using statistical methods and the table of coefficients, the table of residuals and the analysis of variance table of the data related to bond strength were presented and the adequacy of the presented model was examined. The results showed that by reducing the reduction ratio in the cold rolling process and also reducing the initial thickness of the sheets, the bond strength of the bilayer sheet has decreased. Then, bond strength optimization was done as a function of input parameters. The results indicated that the bonding strength reached its maximum level at the thickness of the aluminum layer = 2 mm, the thickness of the stainless-steel layer = 1.3 mm and reduction = 75%.
