Optical Microstructure, FESEM, Microtensile, and Microhardness Properties of LM 25-B4Cnp-Grnp Hybrid Composites Manufactured by Selective Laser Melting

The current investigation, nano-multi-powder particles, 5 and 10 wt.% boron carbide (B4C) graphite (Gr) are utilized as a reinforcement, aluminium LM 25 alloy is used matrix. These hybrid nanocomposites were fabricated by novel additive manufacturing method—selective laser melting. specimen was carried out in cylindrical size having 2 circular slots of dimension 14 length 50 mm. diverse SLM specimens focused on tribological properties impact, creep, tensile, hardness for the three with same weight percentage nanoparticles. consequence reinforcement has been performed through microtensile microhardness tests. evaluated test machine Vickers tester, prepared per ASTM E8 E18 standards. Microtensile strength augmented addition B4C tensile values 668.93 MPa 739.16 MPa, 193VHN 206.79VHN, respectively. result microstructure study shows homogeneous dispersion B4Cnp-Grnp matrix material LM25 alloy. FESEM image results ruined surface illustrate performance ductile fracture, brittle ploughing reinforced material. consequences research enhanced composite added.
