| dc.description.abstractEn | While complex concentrated alloys (CCAs), involving a large fraction of refractory elements, are promising candidates for structural applications, their relatively high densities, processing challenges, and low plasticity, has retarded their development. Here, we report a 3D printable lowdensity precipitation strengthened CCA of composition, Al10Nb15Ta5Ti30Zr40. The chemical homogeneity in the alloy deposited using laser bed powder fusion process is substantially better as compared to the as-cast ingot. This homogeneity is attributed to the enhanced solubility at the high temperatures experienced during laser melting, small melt pool dimensions, and the high cooling rates. The as-built CCA exhibited an excellent balance of room temperature mechanical properties, a compressive yield stress ~1400 MPa, peak stress ~1700 MPa, and plastic strain exceeding 45%. These properties can be attributed to its unique as-processed microstructure consisting of refined grains incorporating a high density of sub-grain boundaries, containing a nanoscale two-phase mixture of an ordered B2 and disordered BCC solid solution phases. | |
