Abstract
7xxx series aluminum alloys possess extremely high cold working yield strength, which make hot working processes essential for component manufacturing. Preheating specimens before or between hot rolling processes significantly affects the mechanical properties of the hot rolled Al alloy sheets, depending on the preheating temperature and time. In this study,.....

DOI:
https://doi.org/10.3365/KJMM.2016.54.12.885
Abstract
The effects of alloying elements (Mn, Cr, and C) on the corrosion resistance of steel were examined using weight loss test, polarization test in a sour environment, analysis of rust, and the prediction of stable corrosion product. Carbon was found to improve corrosion resistance after 7-day immersion, while manganese and.....
