“…Microstructures, crystal lattices and heat treatments that raise the M d temperature result in increase in slip resistance. The CoNiAl alloys exhibit an unusually high M d temperature as evidenced by previous work [4,18]. A comparison of critical stress in compression versus temperature is made in Fig.…”

“…In [001]-oriented Ni 49 Fe 18 Ga 27 Co 6 single crystals the lower critical stress s 0.1 for stress-induced MT in tension than in compression also lead to a stabilization of the stress-induced martensite, and thus, SE sets in only at T 1 ¼ A f þ 30 K, whereas in compression T 1 ¼ A f . A similar asymmetry was observed in [001]-oriented Co 40 Ni 33 Al 27 single crystals [8]. The temperature T 1 is determined not only by the condition T !…”

“…Moreover, NieFeeGa alloys exhibit good conventional shape memory and excellent superelasticity effects. For instance, Ni 54 Fe 19 Ga 27 single crystals stressed in tension along [001] or [012] directions demonstrate high-temperature superelasticity (SE) in a wide temperature interval of about 400 K with reversible strains of up to 8% [3,6,8]. In addition, Efstathiou et al [9] have shown that [001]-oriented Ni 54 Fe 19 Ga 27 single crystals possess excellent fatigue resistance and long fatigue life, exceeding 13,000 cycles at a strain range of 10%.…”

“…Brewer [38] reported that the thermal hysteresis along the [123] and [100] orientations is similar, which might also be the case for the [111] orientation and for the orientation dependence of the stress hysteresis. However, the latter argument needs to be validated experimentally since it has been reported in other SMAs [30,31,35,36,[39][40][41][42] that stress hysteresis can be a function of orientation and stress state.…”

Magnetic shape memory alloys (MSMAs) have recently been developed into a new class of functional materials that are capable of magnetic‐field‐induced actuation, mechanical sensing, magnetic refrigeration, and energy harvesting. In the present work, the magnetic &!hyphen;field‐induced martensitic phase transformation (FIPT) in Ni45Mn36.5Co5In13.5 MSMA single crystals is characterized as a new actuation mechanism with potential to result in ultra‐high actuation work outputs. The effects of the applied magnetic field on the transformation temperatures, magnetization, and superelastic response are investigated. The magnetic work output of NiMnCoIn alloys is determined to be more than 1 MJ m−3 per Tesla, which is one order of magnitude higher than that of the most well‐known MSMAs, i.e., NiMnGa alloys. In addition, the work output of NiMnCoIn alloys is orientation independent, potentially surpassing the need for single crystals, and not limited by a saturation magnetic field, as opposed to NiMnGa MSMAs. Experimental and theoretical transformation strains and magnetostress levels are determined as a function of crystal orientation. It is found that [111]‐oriented crystals can demonstrate a magnetostress level of 140 MPa T−1 with 1.2% axial strain under compression. These field‐induced stress and strain levels are significantly higher than those from existing piezoelectric and magnetostrictive actuators. A thermodynamical framework is introduced to comprehend the magnetic energy contributions during FIPT. The present work reveals that the magnetic FIPT mechanism is promising for magnetic actuation applications and provides new opportunities for applications requiring high actuation work‐outputs with relatively large actuation frequencies. One potential issue is the requirement for relatively high critical magnetic fields and field intervals (1.5–3 T) for the onset of FIPT and for reversible FIPT, respectively.
