Identification of Quaternary Shape Memory Alloys with Near‐Zero Thermal Hysteresis and Unprecedented Functional Stability
Robert Zarnetta,Ryota Takahashi,Ryota Takahashi,Marcus L. Young,Alan Savan,Yasubumi Furuya,Sigurd Thienhaus,Burkhard Maaß,Mustafa Rahim,Jan Frenzel,Hayo Brunken,Yong S. Chu,Yong S. Chu,Vijay Srivastava,Richard D. James,Ichiro Takeuchi,Gunther Eggeler,Alfred Ludwig +17 more
TL;DR: In this article, the lattice parameters of quaternary shape memory alloys and the thermal hysteresis were tailored by using a thin-film composition-spread technique and high-throughput characterization methods.
Journal ArticleDOI
Development of multifunctional thin films using high-throughput experimentation methods
TL;DR: In this paper, the authors describe the use of thin film high-throughput experimentation methods for the efficient development of multifunctional materials, using Ni-Ti-X and ferromagnetic shape memory alloys as examples.
Journal ArticleDOI
Suppression of Ni4Ti3 Precipitation by Grain Size Refinement in Ni‐Rich NiTi Shape Memory Alloys
E. A. Prokofiev,Juri Burow,E.J. Payton,Robert Zarnetta,Jan Frenzel,Dmitry Gunderov,Ruslan Z. Valiev,Gunther Eggeler +7 more
TL;DR: In this article, the effect of grain size on subsequent Ni-rich particle precipitation during annealing was investigated by transmission electron microscopy (TEM), selected area electron diffraction (SAD, SAED), and X-ray diffraction.
Journal ArticleDOI
Phase transformation, structural and functional fatigue properties of Ti–Ni–Hf shape memory thin films
TL;DR: In this paper, the shape memory thin film system was investigated with regard to its structural, phase transformation and functional fatigue properties by means of combinatorial and high-throughput methods.
Journal ArticleDOI
Combinatorial study of phase transformation characteristics of a Ti–Ni–Pd shape memory thin film composition spread in view of microactuator applications
TL;DR: In this article, phase transformation characteristics of a Ti-Ni-Pd shape memory thin film composition spread have been investigated using an ultra-high vacuum combinatorial magnetron sputterdeposition system and subsequent annealing at 500 °C for 1 h in situ.
