Fabrication of Al-based bulk metallic glass by mechanical alloying and vacuum hot consolidation

Synthesis and mechanical properties of bulk Al76Ni8Ti8Zr4Y4 alloy fabricated by consolidation of mechanically alloyed amorphous powders

“…The behavior that the apparent hardness decreases with increasing the applied load is similar to that observed in brittle ceramics, glasses and the conventional crystalline materials [22]. Such phenomena usually referred to the indentation size effect (ISE).…”

Influence of annealing on microstructure and magnetic properties of cobalt-based amorphous/nanocrystalline powders synthesized by mechanical alloying

“…Compared to the rapid solidification techniques, the amorphous powders can be synthesized by MA in wider composition ranges (far from the eutectic temperature) and even from the elemental powders with positive heat of mixing [11]. Furthermore, the bulk glassy alloys with arbitrary shape and size can be fabricated by hot consolidation of the mechanically alloyed glassy powders in the temperature range of the supercooled liquid region, where the viscosity drops significantly [12,13]. Since MA is usually conducted at room temperature, it is expected that amorphous phase in the as-prepared powders should be in a more unrelaxed state with respect to that http of as-quenched alloys.…”

Nanocrystalline or amorphous matrix Al60Fe15Ti15(Co/Mg/Zr)5–5%B composites produced by consolidation of mechanically alloyed powders – lightweight materials with high hardness

“…Considering Al-based alloys, the formation of an amorphous phase by mechanical alloying was detected in the case of binary AleFe, AleTi systems [8,10,11] and Al 50 Fe 25 Ti 25 [12], Al 60 Fe 20 Ti 15 Ni 5 [13], Al 75 Ni 10 Ti 10 Zr 5 [14] and Al 82 La 10 Ni 4 Fe 4 [15] compositions (here, and throughout the article, compositions of alloys are given in at.%).…”
