This paper aims to investigate the copper and the magnesium effects on the microstructure, on the hardness, and on the resistance to micro-abrasive wear of the alloy Al–19Si. Early findings could show that the hypereutectic Al–Si alloys fabricate

The microstructure of a 240 mm diameter AISI 4340 mill shaft, quenched and tempered, was analyzed through its longitudinal cross section. Normally, higher cooling rates promote martensitic structure while the diffusion assisted austenite decompositio

Fe-24Al(at.%) base alloys containing 0–6 at.% Cr were elaborated by melting and casting under argon atmosphere. The ingots obtained were initially homogenized at 1000 °C for 5 h in air, then hot rolled at temperatures in the range 1000-800 °C. Th
