Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Effect of Slenderness Ratio on Crack Parameters of Simply Supported Shaft
Procedia Materials Science, 2014 AbstractTransverse crack is a common occurrence present in over simply supported shaft. The development of crack in a shaft is leads to catastrophic failure, which will affect the dynamic behavior such a local stiffness and stress intensity factor of the given shaft.
