In this work a traditional high entropy alloy (FeCoNiCrAl) was reinforced by uniformly distributed reactive silicon carbide (SiC) particles by a powder metallurgy synthetic route, using as precursors simply mixed powders or mechanically prealloyed on

The aim of this work was to investigate the field assisted powder metallurgy route for producing HEAs at equimolar composition, i.e. FeCoNiCrAl, starting from metal powders. Both mixed, mechanically activated and mechanically alloyed powders have bee

Titanium-based discontinuously reinforced metal matrix composites were obtained by mechanical alloying and spark plasma sintering. Titanium sponge was used as a raw material to minimize costs, and a small amount of calcium was added as a process cont

The mechanical alloying of titanium with 3 wt% chromium was performed starting directly from Hunter or Kroll titanium sponge. A small quantity of calcium was added as a process control agent (PCA) to obtain a high process yield, uniform microstructur

The mechanical alloying of titanium has previously been performed using fugitive process control agents (PCAs). In this work, calcium, magnesium, MgY or CrY are used as process control agents to balance between the cold welding and fracture phenomena

In this work, the influence of specimen width (in the range 6–15 mm) on the tensile deformation and fracture behaviour of AA5182 aluminium alloy sheets, characterised by the Portevin-Le Chatelier effect, was investigated. The experimental results s
