The corrosion evolution of 2024-T351 and 7075-T651 aluminum alloys in the thin electrolyte layer (TEL) wet–dry alternating cycle (WDAC) environment is studied this work. results show that TEL environment, competitive effect between H+ accelerates reactions deposition sulfate impedes attacks exists during exposure. difference with increasing HSO3−, subsurface intergranular on promoted to form ex...

Abstract The mechanical properties of the Al-7075 material, which is used in important areas such as automotive, aviation and defense industry, are still being studied by researchers. In this study, effects different proportions Nb additives on microstructure rapidly solidified alloy was investigated. Rapid solidification processes were carried out with a single roller melt spinner at disk surf...

Abstract The characteristics and structural performance of a composite material’s properties are better than those its component parts because It comprised pair or more insoluble, chemically separate stages. functioning alone. ‘Metal-Matrix’ composites materials that have been produced from metals ceramics had fibers particles incorporated into them to enhance their physical characteristics. fa...

Aluminium alloys are becoming increasingly popular due to the demands for high-performance lightweight components, and semi-solid metal processing (SSM) is a technique forming near-net-shape complex components with far fewer defects associated turbulent filling. The deformation mechanisms of 7075 aluminium alloy were studied through direct partial re-melting method using as-extruded billets. It...
