A novel gradient composite material CrMnFeCoNiB2C0.5 prepared by laser melting deposition

A novel gradient composite of CrMnFeCoNiB2C0.5 was prepared by laser melting deposition (LMD). The heat accumulation during LMD results in thin-walled structure that exhibit significant structural gradients. The material was tested with an ultimate compressive stress of 1.56 ± 0.067 GPa and a compre...

Zusammenfassung:A novel gradient composite of CrMnFeCoNiB2C0.5 was prepared by laser melting deposition (LMD). The heat accumulation during LMD results in thin-walled structure that exhibit significant structural gradients. The material was tested with an ultimate compressive stress of 1.56 ± 0.067 GPa and a compressive strain of 19.17 ± 1.96%. Such materials have the potential to prepare additive manufactured parts with locally-controllable strength and plasticity by simply varying the thermal input only.
