Journal ArticleDOI
Processing a glass-forming Zr-based alloy by selective laser melting
TL;DR: In this article, the authors used density contour maps to identify the process window, which allows obtaining fully glassy samples with a high relative density of up to 98.5%.
Journal ArticleDOI
Significant tensile ductility induced by cold rolling in Cu47.5Zr47.5Al5 bulk metallic glass
Kaikai Song,Simon Pauly,Y. Zhang,Sergio Scudino,Piter Gargarella,Kumar Babu Surreddi,Uta Kühn,Jürgen Eckert +7 more
TL;DR: In this paper, the authors obtained significant tensile plasticity up to 0.7 ± 0.1% together with work-hardening and larger fracture strength in bulk metallic glass with only 2.9± 0.3% thickness reduction.
Journal ArticleDOI
Influence of processing parameters on the fabrication of a Cu-Al-Ni-Mn shape-memory alloy by selective laser melting
Tobias Gustmann,A. Neves,Uta Kühn,Piter Gargarella,Claudio Shyinti Kiminami,Claudemiro Bolfarini,Jürgen Eckert,Simon Pauly +7 more
TL;DR: In this paper, a shape-memory alloy 81.95Cu-11.85Al-3.2Ni-3Mn (wt.%) was processed by selective laser melting (SLM) and the parameters were optimized to obtain compact, fully martensitic samples with a high relative density of up to 99%.
Journal ArticleDOI
Short-range order of Zr62−xTixAl10Cu20Ni8 bulk metallic glasses
TL;DR: In this article, the atomic pair correlation functions of the first crystallization products are similar for all titanium contents and there is no indication of any special atomic arrangement for the particular alloy forming quasicrystals upon heating.
Journal ArticleDOI
Ti–Cu–Ni shape memory bulk metallic glass composites
Piter Gargarella,Simon Pauly,Kaikai Song,J. Hu,N.S. Barekar,M. Samadi Khoshkhoo,A. Teresiak,Horst Wendrock,Uta Kühn,Christoph Ruffing,Eberhard Kerscher,Jürgen Eckert +11 more
TL;DR: In this paper, a deformation mechanism is proposed with the help of experimental observations and finite-element simulation, which demonstrates that stress concentrations occur around the precipitates, which promotes a heterogeneous stress distribution and the formation of multiple shear bands.
