      abstract     = {NiTi-based composites possess great potential for
                      concurrently improving both mechanical and functional
                      properties. However, relying on traditional alloy design
                      principles limits the design space and greatly hinders the
                      advancement of high-performance NiTi-based composites. The
                      concept of high-entropy alloys has expanded the
                      compositional landscape, unveiling unique structural
                      characteristics for alloy design and providing new prospects
                      for addressing these limitations. Here, we report a
                      compositionally complex NiTi-based composite that exhibits
                      exceptional strength and ductility, along with remarkable
                      recoverable strain. The composite,
                      Ni$_{40}$Ti$_{40}$(NbMoTaW)$_{20}$ (at.\%), comprises a 78.0
                      \% B2 NiTi matrix, a 19.2 \% Nb-Mo-Ta-W-Ti-Ni
                      compositionally complex body-centered cubic (BCC) phase, and
                      a small amount of Ti2Ni. Notably, this composite
                      demonstrates an engineering compressive strength of 3274
                      MPa, with a compressive fracture strain of 44.2 \% and a
                      maximum recoverable strain of 7.3 \% (5.6 \% elastic strain
                      and 1.7 \% inelastic recoverable strain). These outstanding
                      mechanical properties result from the unique structural
                      characteristics of the compositionally complex phase and the
                      lattice strain matching induced by phase transitions. The
                      substantial recoverable strain was obtained through the
                      reversible B2⇌R⇌B19′ phase transition. This work not
                      only innovates a new category of high-performance NiTi-based
                      composites but also extends the applicability of the
                      high-entropy concept.},
