<p>Co-V-Ga-based shape memory alloys have shown great potential in the field of solid-state elastocaloric refrigeration due to their low stress hysteresis (∆<i>σ</i>_hys) and excellent superelasticity. However, large applied stress and low adiabatic temperature change (Δ<i>T</i>_ad) greatly limit the application of Co-V-Ga-based alloys as elastocaloric materials. Here, we have successfully achieved a breakthrough in material properties by innovatively introducing the co-doping strategy of Mn and Ti elements. It was found that the synergistic effect of Mn and Ti significantly enhanced the mechanical properties of the Co₅₂V₃₁Ga₁₄Mn₁Ti₂ alloy through solid solution strengthening, fine grain strengthening, and precipitation strengthening mechanisms. A large Δ<i>T</i>_ad of −11&#xa0;K was obtained for the Co₅₂V₃₁Ga₁₄Mn₁Ti₂ bulk polycrystalline alloy under a very low applied stress of 380&#xa0;MPa. This is mainly due to the strong texture of &lt; 001 &gt; _A. Texture strengthening is the key factor to improve the elastocaloric effect of alloys. At the same time, the Co₅₂V₃₁Ga₁₄Mn₁Ti₂ alloy still maintains a Δ<i>T</i>_ad of −4&#xa0;K without an obvious attenuation trend after 350 elastocaloric cycles under the applied stress of 300&#xa0;MPa. In addition, due to the low energy dissipation (∆<i>W</i>), the energy conversion efficiency of the elastocaloric response is greatly improved, so that the coefficient of performance (COP) of the Co₅₂V₃₁Ga₁₄Mn₁Ti₂ alloy material is as high as 28.9, far exceeding most of the current shape memory alloy elastocaloric materials. As a result, the co-doping of Mn and Ti elements makes it possible to prepare an elastocaloric refrigeration alloy with low applied stress and a large elastocaloric effect.</p> Graphical abstract <p></p>
