Abstract Scope |
Designing materials to have balance of material properties, for example, at the interfaces between plasma-material and environment-material is a major challenge in industry currently. Functional graded materials (FGM’s) having localized material composition presents a potential design solution. FGM of Tungsten on 316L Stainless Steel (W-SS) is fabricated using Laser Powder Bed Fusion (LPBF). Material characterization: microstructure, element distribution, phase distribution, and microhardness of W-SS interface was done. A hardness-based model was used to predict the strength of the bond. The results showed a good bonding with keyhole mode of the melt pool at the W-SS interface. EDS and XRD analysis of the interlayer indicate the presence of W-Ni and W-Fe intermetallic phases. Mechanical properties: microhardness across materials’ interface and correlated strengths showed a smooth transition and a high bond strength respectively. |
