Micro-lateral extrusion of Zr55Cu30Al10Ni5 bulk metallic glass under low-frequency vibration loading

MATEC Web of Conferences, 2015
The effect of vibration on the micro-forming ability of Zr55Cu30Al10Ni5 bulk metallic glass in its supercooled liquid region was studied. The experiment of micro-extrusion was carried out under different amplitude (38 ∼ 760 N) and different frequency (0 ...

Crystallization kinetics of GdYScAlCo high-entropy bulk metallic glass

Chimica Techno Acta, 2023
The thermal stability and non-isothermal crystallization of a new bulk-amorphous high-entropy (HE-BMG) equiatomic GdYScAlCo alloy were studied by differential scanning calorimetry (DSC). The alloy shows a four-stage crystallization process.

New Class of Plastic Bulk Metallic Glass [PDF]

Physical Review Letters, 2008
An intrinsic plastic Cu(45)Zr(46)Al(7)Ti(2) bulk metallic glass (BMG) with high strength and superior compressive plastic strain of up to 32.5% was successfully fabricated by copper mold casting. The superior compressive plastic strain was attributed to a large amount of randomly distributed free volume induced by Ti minor alloying, which results in ...

Properties of bulk metallic glasses

Russian Journal of Non-Ferrous Metals, 2016
A relatively small number of revolutionary materials have been discovered in the field of physical metallurgy and metal physics in the last several decades, and bulk metallic glasses are among them. Their strength and hardness are considerably higher and their modulus of normal elasticity is considerably lower than that of crystalline alloys, which ...
