21. Process Understanding and Weldability of Laser-Powder Bed Fusion Manufactured Alloy 718
Abstract : Laser-powder bed fusion (L-PBF) is an additive manufacturing (AM) process that involves building components by fusing fine metal powders using laser. There is no universal set of process parameters that can yield optimum results for all the different materials, geometries, and L-PBF machines. READ MORE

22. Post-treatment of Alloy 718 produced by electron beam melting
Abstract : Electron beam melting (EBM), a metal additive manufacturing (AM) process, has received considerable industrial attention for near net shape manufacture of complex geometries with traditionally difficult-to-machine materials. This has fuelled considerable academic interest in investigating EBM of Alloy 718, a nickel ironbased superalloy possessing an exciting combination of good mechanical behaviour and cost effectiveness.

23. Electron beam-powder bed fusion of Alloy 718 : Effect of process parameters on microstructure evolution
Abstract : Additive manufacturing (AM) is the technology of building 3D parts through layer-by-layer addition of material. Of the different types of AM techniques, electron beam-powder bed fusion (EB-PBF) has been used in this study. EB-PBF can build parts by melting metallic powders using an electron beam as the energy source. READ MORE

24. Diabetes mellitus and risk of prostate cancer - A focus on shared risk factors and survivor bias
Abstract : Prostate cancer (PCa) is a heterogenous disease including very aggressive lethal tumors to incidentally discovered clinically insignificant tumors. Age, ethnicity, and family history are the only established risk factors. READ MORE

25. Electron beam melting of Alloy 718 : Influence of process parameters on the microstructure
Abstract : Additive manufacturing (AM) is the name given to the technology of building 3D parts by adding layer-by-layer of materials, including metals, plastics, concrete, etc. Of the different types of AM techniques, electron beam melting (EBM), as a powder bed fusion technology, has been used in this study.
