Medical applications are today the most important areas that use additively manufactured parts. The choose of the convenient biomaterial during implant design depends on several criteria such as biocompatibility, osteointegration and processing cost. The purpose of this work is to compare the corrosion behavior of AISI 316L austenitic stainless ste...

The impact of sterilization on the corrosion behavior of orthopedic implants produced via Laser Powder Bed Fusion is analyzed in a biologically relevant environment. In a controlled environment at 37 °C, experiments were conducted to mimic a natural biological state. In a controlled oven at 50 °C for 20 min, AISI 316L stainless steel samples were p...

In this study, both experimental and numerical investigations are carried out on samples fabricated by additive manufacturing (AM). The determination of stress distribution in parts obtained by AM, even for simple tensile test, is complicated because it is largely influenced by many manufacturing parameters as the adopted infill pattern, the infill...

In this study, Tin monosulfide SnS semiconductor absorbers was deposited by chemical spray pyrolysis route on the glass substrate. We examined the impact of substrate temperature on the structural, morphological, linear optical and electrical characteristics of SnS absorber at many substrate temperatures such as 50 °C, 375 °C and 400 °C. The SnS fi...

The experimental study exposed in this paper aims to exhibit the effect of the bending moment and the preload on bolts. A bolted tee-stub connection defined in Eurocode 3, part-1–8, is used. The flanges of the tee-stubs are taken from IPE400 and HEB 320 beams. The HR-M12-10.9 bolts are used and are equipped with four strain gauges each. The strains...

The transition to a green steel making is a journey over decades that involves many technologies and pathways, in most scenarios with the use of hydrogen − both as reductant and as fuel − as the endgame. The paper describes a general pathway to decarbonisation including increased energy efficiency, use of low carbon fuels, carbon capture, and use o...
