A study of hot rolling of 6061 aluminum alloy matrix composite reinforced with SnO2-coated Al18B4O33 whisker

► SnO2 coating improves hot-rolling formability of ABOw/6061Al composite. ► The suitable SnO2 coating content enhances the tensile properties. ► The excessive SnO2 coating content deteriorates the tensile properties. ► There is an optimal SnO2 coating content for the high tensile properties.
