Pd20Pt20Cu20Ni20P20 high-entropy alloy as a bulk metallic glass in the centimeter
TL;DR: In this article, a Pd20Pt20Cu20Ni20P20 bulk metallic glass (BMG) with a high-entropy (HE) alloy composition and a maximum diameter of 10mm was fabricated by fluxed water quenching.
Journal ArticleDOI
Structural rejuvenation in a bulk metallic glass induced by severe plastic deformation
Wojciech Dmowski,Yoshihiko Yokoyama,Andrew Chihpin Chuang,Yang Ren,Minoru Umemoto,Koichi Tsuchiya,Akihisa Inoue,Takeshi Egami,Takeshi Egami +8 more
TL;DR: Using high-energy X-ray diffraction, the authors examined the atomic structure in bulk metallic glass samples which underwent severe plastic deformation by the high-pressure torsion (HPT) technique.
Journal ArticleDOI
Stable Icosahedral Al–Pd–Mn and Al–Pd–Re Alloys
Journal ArticleDOI
Reversible transition of deformation mode by structural rejuvenation and relaxation in bulk metallic glass
TL;DR: In this paper, a transition from heterogeneous, localized deformation to homogeneous deformation was observed in Zr50Cu40Al10 bulk metallic glass (BMG) by giant straining using the high pressure torsion (HPT) method.
