Defects-tolerant Co-Cr-Mo dental alloys prepared by selective laser melting

Highlights • Heterogeneous macro-micro and nanostructures were formed in the CoCrMo alloys prepared by SLM. • The interlocking of “weld lines” and elongated grains generated 3D textures resembling weaved fabrics. • The formed textures compensated the micro-faults making the SLM CoCrMo alloys “defect...

Zusammenfassung:	Highlights • Heterogeneous macro-micro and nanostructures were formed in the CoCrMo alloys prepared by SLM. • The interlocking of “weld lines” and elongated grains generated 3D textures resembling weaved fabrics. • The formed textures compensated the micro-faults making the SLM CoCrMo alloys “defects-tolerant”.
