Purpose: The goal of this work is to investigate structure and properties of powdersAl67Ti25Fe8 alloys obtained by mechanical alloying. Design/methodology/approach: The powders of the Al67Ti25Fe8 alloys were obtained by mechanical alloying method in a planetary Fritsh Pulverisette 5 mill. The changes of the constitution phases were tested by means of the X-ray diffractometer. The microscopic ob...

In this work infiltration behavior of mechanical alloyed 75 wt% Cu – 25 wt% WC powders into porous WC compacts were studied. Owing to their ductile nature, initial Cu powders were directly added to mechanical alloying batch. On the other hand initial WC powders were high energy milled prior to mechanical alloying. Contact infiltration method was selected for densification and compacts prepared ...

Cu–Cr-Zr alloys had wide applications in engineering applications such as electrical and welding industrial especially for their high strength, high electrical as well as acceptable thermal conductivities and melting points. It was possible to prepare the nano-structure of these age hardenable alloys using mechanical alloying method as a cheap and mass production technique to prepare the non-eq...

Mechanical alloying is a technique involving the production of alloys and compounds, which permits development metastable materials (with amorphous or nanocrystalline microstructure) obtention solid solutions with extended solubility [...]
