title = "Enhancing of aluminum alloy 1050-H4 tensile strength by accumulative roll bonding process",
abstract = "The accumulative roll-bonding process (ARB) was performed on commercially available AL-1050-H4 aluminum alloy. Samples were rolled for two passes. In ARB process, thickness is reduced by 50% for each pass. The aim of performing the ARB process was to refine the grain structure of aluminum 1050-H4 to increase its tensile strength. A tensile test was performed at room temperature and at a steady strain rate with the aim of determining whether ARB increases the mechanical properties of aluminum 1050-H4 and identify the moment the material experience high ultimate tensile strength. Samples were cut according to standard test methods for tension testing of metallic material (ASTM) at rolling direction (RD). Information about the microstructure of samples was obtained using a scanning electron microscope (SEM). The highest UTS was obtained on the 1st pass and was reported as 127.1 MPa and the lowest UTS was discovered on parent sample and reported as 111.7 MPa. It was also observed that E-modulus and percentage elongation decreased due to the ARB process. It was noticed that after several rolling process, material surface temperature increases. The increase in surface temperature led to increase in particle size which was discovered on 2nd pass of ARB process which result in material losing its mechanical properties.",
