Abstract Laser directed energy deposition (L-DED) was used to produce samples of the newly patented W360 hot work tool steel by Böhler. The process parameters were optimized obtain nearly fully dense through production and analysis single deposited tracks layers. Subsequently, bulk underwent a hardening heat treatment, consisting austenitizing, air quenching, tempering. analysed in as-built con...

The impact of moisture on flowability and spreadability is discussed. More notably we also present research the built nickel-base material. One lot a newly opened Hastelloy X (HX) L?PBF powder was split into two equal batches. batch moisturized using programmable climate chamber, other untreated. We bars with both batches for mechanical testing, in an EOS M100, cold build plate. content batches...

Understanding the laser-powder interaction during laser powder bed fusion (LPBF) of composite systems is vital in producing robust parts. The currently existing mechanically mixed powders are unable to meet requirements an ideal for LPBF process, even if metallic particles remain highly spherical with a second constituent attached them. It was found that presence reinforcing agent (i.e., B4C) o...

Mass production of high-quality graphene with low cost is the footstone for its widespread practical applications. We present herein a self-limited growth approach for producing graphene powders by a small-methane-flow chemical vapour deposition process on naturally abundant and industrially widely used diatomite (biosilica) substrates. Distinct from the chemically exfoliated graphene, thus-pro...

Dual amide hydrogen bond crosslinked and strengthened high strength supramolecular polymer conductive hydrogels were fabricated by simply in situ doping poly (N-acryloyl glycinamide-co-2-acrylamide-2-methylpropanesulfonic) (PNAGA-PAMPS) hydrogels with PEDOT/PSS. The nonswellable conductive hydrogels in PBS demonstrated high mechanical performances-0.22-0.58 MPa tensile strength, 1.02-7.62 MPa c...
