Mechanical Properties, Microstructures, and Textures of Cold Rolling Sheets Made from a Low-cost Continuous Cast Al-1.5Cu Alloy with Potential Application in Auto Sheets

Mechanical propertiesMechanical properties, microstructuresMicrostructure and texturesTextures of cold rollingRolling sheets from a low-cost continuous castingContinuous casting (CC) Al-1.5Cu alloy were characterized and investigated thoroughly using tensile testing machine, Optical & Scanning Electron microscopes (SEMScanning electron microscopy (SEM)), and X-ray diffractometer (XRD). Compared with AA5xxx and AA3xxx aluminum alloysAluminum alloys, ascribing to the precipitationPrecipitation and solid solution of Al-Cu phase, material characteristics of the Al-Cu alloyAl-Cu alloys after cold rollingRolling at different gauges are significantly different with some interesting findings. The findings from the cold rollingRolling hardening would potentially affect the subsequent processingProcessing, such as solid solution heat treatmentHeat treatment, quenching, forming, and agingAging, for application (replace AA5xxx-O sheet) in auto sheets.
