Effect of off-stoichiometric compositions on microstructures and phase transformation behavior in Ni-Cu-Pd-Ti-Zr-Hf high entropy shape memory alloys
David Piorunek,O. Oluwabi,Jan Frenzel,Aleksander Kostka,Hans Jürgen Maier,Christoph Somsen,Gunther Eggeler +6 more
TL;DR: In this article, the effects of the addition of additional alloy elements on microstructures and phase transformations of high entropy shape memory alloys (HE-SMAs) were studied.

The Influence of Zirconium on the Low-Cycle Fatigue Response of Ultrafine-Grained Copper
TL;DR: In this paper, the cyclic stability of ultrafine-grained (UFG) oxygen-free highconductivity (OFHC) copper (Cu) of originally high (99.995 wt pct) purity processed via equal-channel angular extrusion (ECAE) was investigated.

Compressive shape memory actuation response of stress-induced martensite aged Ni51Fe18Ga27Co4 single crystals
E. Yu. Panchenko,E. E. Timofeeva,Yu. I. Chumlyakov,K. S. Osipovich,A. I. Tagiltsev,Gregory Gerstein,Hans Jürgen Maier +6 more
TL;DR: In this paper, the effects of stress-induced martensite aging (SIM-aging) in twinned L10-martensite on the functional properties of [001]A-oriented Ni51Fe18Ga27Co4 (at%) single crystals were systematically investigated.

Formation and growth of voids in dual-phase steel at microscale and nanoscale levels
Gregory Gerstein,Hans-Bernward Besserer,Florian Nürnberger,Luis A. Barrales-Mora,Lasar S. Shvindlerman,Yuri Estrin,Hans Jürgen Maier +6 more
TL;DR: In this article, the mechanisms of nucleation and growth of voids were analyzed in a dual-phase steel DP600 at different strain states and forming temperatures, and a correlation between the shape of the voids and their location in the crystal lattice was found, whereby the mechanism of their nucleation, growth and coalescence could be described.

Microstructure Formation in Cast TiZrHfCoNiCu and CoNiCuAlGaIn High Entropy Shape Memory Alloys: A Comparison
Tetiana Kosorukova,Gregory Gerstein,Valerii V. Odnosum,Yuri Koval,Hans Jürgen Maier,G.S. Firstov +5 more
TL;DR: The present study is dedicated to the microstructure characterization of the as-cast high entropy intermetallics that undergo a martensitic transformation, which is associated with the shape memory effect, and it is shown that the TiZrHfCoNiCu system exhibits strong dendritic liquation, which leads to the formation of martensite crystals inside the dendrites.
