Laser metal deposition (LMD) additive manufacturing was utilized to fabricate a Cu‒9Al‒5Fe‒5Ni alloy with a hierarchical microstructure and superior mechanical strength. An optimized processing window of LMD was established for printing the alloy with a relative density greater than 99% using laser...
