Experimental investigation of formability of Al/Mg/Al strips fabricated via cold roll bonding process
Abstract
Cold roll bonding (CRB) process is a method for production of multi-layered sheets with same and dissimilar materials that, in the past decade has been attracted the attention of many researchers. In the present study, for the first time, formability of Al/Mg/Al composite which was fabricated by the CRB process was investigated by using the Nakazima test and forming limit diagram (FLD). Also, mechanical properties were studied by carried out uniaxial tensile test and microhardness test. Tensile fracture surfaces were demonstrated by scanning electron microscope (SEM) to define the fracture mode. The Al/Mg/Al composite was fabricated using a rolling machine, and a thickness reduction of %70 was applied at room temperature and without lubricant. It was observed that a good bonding between the Al/Mg layers fabricated via CRB process and as expected, increase strength, microhardness and decrease elongation and formability compared to the initial strip due to strain hardening and cold work. The Al/Mg/Al composite prepared via CRB process was annealed due to decreased the work hardening and created the stronger bonding between Al and Mg layers. Annealing and cooling were done in the furnace at 300°C for 60 min and in the air at ambient temperature, respectively. Finally, the value of microhardness of Al and Mg layers reaches to 98.8HV and 91.6HV, respectively and the strength value is about 1.73 and 1.84 times higher than that of the initial aluminum and magnesium sheets, respectively. Also results of SEM demonstrated that dimples shallower and smaller than the initial sample.
