“…Hern andez-Navarro et al 32 and also higher than in other similar alloys previously reported. 22,31,33 Nevertheless, this value is slightly lower than the one presented in Ni 54 Fe 19 Ga 27. 34 It is worth noticing that the reversible adiabatic temperature change in our Ni 50 Mn 32 In 16 Cr 2 alloy due to Dr ¼ 75 MPa is comparable with that presented in the Ni 45.7 Mn 36.6 In 13.5 Co 4.2 alloy due to an Dl 0 H ¼ 2 T external magnetic field.…”

We have studied the correlation between the elastocaloric effect and the crystallographic direction where a uniaxial stress is applied in a textured polycrystalline Ni-Mn-In-Cr ferromagnetic shape memory alloy; this alloy displays martensitic transformation around room temperature and presents an L21 cubic structure in the austenite phase. The texture in the material was induced by simple arc melting synthesis; using inverse pole figures, a favored grain growth was shown in the direction [001] perpendicular to the cooled surface. The elastocaloric effect was determined by direct measurements of the adiabatic temperature change (ΔTadme), while compressive stress was applied and released; hereby, it has been shown that it is possible to exploit the columnar growth texture in order to obtain a large and reversible elastocaloric effect. The reversible elastocaloric response was measured between 280 and 310 K by applying moderate stresses of 50, 75, and 100 MPa in the [001], [111], and [011] directions. A strong interrelation was found in the cyclic ΔTadme values of −3.9, −2.0, and −1.3 K after unloading a compressive stress of 100 MPa applied mainly in the [001], [111], and [011] directions, respectively.

“…Meanwhile, the field-induced adiabatic temperature change T ad is an important parameter quantifying the caloric effect. Figure 5 demonstrates the comparison of the cyclability of elastocaloric effect and T ad of the alloys designed here with other elastocaloric materials in the polycrystalline form [4][5][6]16,[19][20][21][22][23]. As compared to other materials except Ti-Ni-based alloys, the present (Ni 51 Mn 33 In 14 [1].…”

“…Besides stressinduced transformation, the present alloys also exhibit magnetic-field-induced transformation (as shown in The 'Cycles' denote the number of cycles of elastocaloric effect reported in literature; since most of the studies did not mention whether failure occurred after such cycles, this number does not necessarily corresponds to fatigue life. Data in this figure were taken from the present study and literature: Ti-Ni film [4], Ti-Ni-Cu film [4], Ti-Ni-V [21], Ti-Ni [23], Ni-Mn-In [6], Cu-Zn-Al [5], Ni-Co-Mn-In [16,19], Ni-Mn-Ga [20], Ni-Fe-Ga [22].

Multiferroic phase-transforming alloys demonstrate intriguing multicaloric effects, but they are intrinsically brittle and their elastocaloric effect shows poor cyclability, which remains a major challenge for exploiting more efficient multicaloric refrigeration. Here, by employing a novel strategy of strengthening grain boundary, the cyclability of elastocaloric effect in the prototype Ni-Mn-based multiferroic phase-transforming alloys is strikingly enhanced by two orders of magnitude. Ultrahigh cyclability of a large elastocaloric effect is achieved. This not only paves the way for exploiting multicaloric effects for more efficient cooling, but also provides a strategy for overcoming the cyclability issues in the ubiquitous brittle intermetallic phase-transforming materials. IMPACT STATEMENTThe cyclability of elastocaloric effect in the prototype Ni-Mn-based multiferroic phase-transforming alloys has been strikingly enhanced by two orders of magnitude through employing the strategy of strengthening grain boundary.
