Mechanical and tribological properties of Zr–Al–Ni–Cu bulk metallic glasses

Evolution of loops in ductile Zr-based bulk metallic glass during plastic deformation

“…Microhardness value was found to be 492 ± 15 H v for the alloy which is comparable to other Zr-based BMGs [9]. engineering stress-strain curves for Zr 60 Al 16.5 Ni 13.5 Cu 10 .…”

Electronic structure and phase stability during martensitic transformation in Al-doped ZrCu intermetallics

“…Zr-Cu-Al has been reported as one of the most successful and promising alloy systems to form BMGs [11,[24][25][26][27][28][29][30] and metallic glass composites containing ZrCu austenite and martensite phases [14][15][16][17][19][20][21][22]. The investigations on the phase stability and martensitic transformation of the Al-doped ZrCu quasi-binary intermetallics have not yet been performed.…”

Study of mechanical property and crystallization of a ZrCoAl bulk metallic glass

“…Room temperature compression tests of Zr 74.9 Ti 10.5 Ni 14.6 nanostructure-dendrite composite show evident yielding and 6% plastic strain together with work hardening up to 1622 Mpa [18]. Furthermore, for quaternary components Zr 61 Al 12.2 Ni 5 Cu 21.8 , Zr 60.6 Al 13.6 Ni 7.5 Cu 18.3 and Zr 60 Al 15-Ni 10 Cu 15 have a fracture stress of about 1750e1800 Mpa and plasticity less than 1.8% under compression tests [17].…”
