The pres.nt s.udy focus.s.on inves.igating the micros.ructural evolutions.and mechanical properties.of energetic Al_(1)(TiZrNbTaMoCr)_(15) refractory high-entropy alloys.with the different heat treatments.at low Al content s.ate. It is.found that even with a reduction in the Al content, the s.rength of thes. alloys.remains.unaffected at room temperature and high temperature, while the plas.icity improves.s.gnificantly. In particular, the coherent BCC/B_(2) micros.ructure with needle-like B_(2) nanoprecipitates.dis.ers.d into the BCC matrix is.formed in 873 K-aged Al_(1)Ti_(6)Zr_(2)Nb_(3)Ta_(3)Mo_(0.5)Cr_(0.5) alloy. Therefore, this.alloy exhibits.the highes. compres.ion yield s.rength (σ_(Ys. = 1333 and 717 MPa) at room temperature and 1073 K, res.ectively. After 973 K-aged, the coherent BCC/B_(2) micros.ructure underwent des.abilization, and the B_(2) phas. trans.orms.into the brittle Zr5Al3 phas. which then coars.ns.and dominates.the micros.ructure of s.-AlTa_(3) alloy after 1073 K-aged. Moreover, thes. current alloys.exhibit exceptionally high theoretical exothermic enthalpy (ΔH), s.rpas.ing 11606 J·g^(−1), which highlights.their s.gnificant potential as.innovative high-performance energetic s.ructural materials.
