Controlling the surface roughness of materials manufactured by laser powder bed fusion (L-PBF) is critical for achieving functional performance components and improving their mechanical properties. This important whose surfaces cannot be post-treated using subtractive methods. In this study, has been investigated applying different power scanning speed combinations. Furthermore, potential effects locations on build platform have considered as well. The regression models developed significant...
Porous tantalum has been extensively used in orthopaedic surgery, including uncemented total knee arthroplasty (TKA). Favourable results were reported with earlier monobloc tibial components and the design evolved to modular implants. We aimed analyse possible causes for extensive medial tibia bone loss, resulting porous baseplate fracture after primary TKA. Retrieved tissue samples scanned 3 MeV focused proton beam Proton-Induced X-ray Emission (micro-PIXE) elemental analysis. Fractographic...
Since ozone is highly corrosive, it can substantially affect the mechanical and chemical properties of materials; consequently, could applicability those materials in medical applications. The effect sterilization on additively manufactured specimens biocompatible poly(methyl-methacrylate) was observed. FDM 3D-printed PMMA groups five were exposed to high concentrations generated by corona discharge for different durations at inside an enclosed chamber with embedded calibrated ozone,...
Wood-based materials offer a high potential for the lightweight design of modern car bodies. Therefore, this prestudy investigates static strength screw-bonded lap joints 1 mm-thick sheets EN AW-6016-T4 aluminum alloy and 4.5 plates consisting three 1.5 cross-laminated beech veneers. Plates with cover veneers oriented longitudinal (L) or transverse (T) to uniaxial loading direction veneer stacking orders designated as L/T/L T/L/T were used. Two self-cutting screws polyurethane-based adhesive...
This work investigates the influence of sheet edge condition on fracture behavior riv-bonded aluminum-magnesium lap joints under monotonic-static and cyclic-dynamic shear-tensile loads. Therefore, sheets 1.5 mm-thick EN AW-6016-T4 aluminum alloy were joined with 2.0 AZ91 magnesium using two C5.3×6.0-H4 rivets epoxy-based adhesive. The side edges either shear-cut or milled after cutting. Before testing, heat-treated at about 180-200 °C for 20 min in order to cure adhesive peak-age alloy....
The heterogeneity of welded joints' microstructure affects their mechanical properties, which can vary significantly in relation to specific weld zones. Given the dimensional limitations available test volumes such material zones, determination properties presents a certain challenge. paper investigates X joint S690QL1 grade high strength steel (HSS), with slightly overmatching filler metal. experimental work is focused on tensile testing obtain stress-strain as well fracture mechanics...
The static and dynamic loading capacities of components depend on the stress level to which material is exposed. fatigue behavior materials manufactured using additive technology accompanied by a pronounced scatter between number cycles at same level, significantly greater than from with chemical composition, e.g., AISI 316L, but produced rolling or forging. An important reason lies in fact that cracks are initiated almost always below surface loaded specimen. Thus, article, assuming crack...
Assessment of the bearing capacity welded joint (all its zones) high-strength steel has an important role for safe use structure. The represents a key problem due to heterogeneity, mechanical and operational properties, as well presence crack-type defect. behaviour with crack is unpredictable influence many factors on it. In order better understand base material joint, it necessary carry out appropriate tests. This paper presents determination plate (material S960MC) semi-elliptical in HAZ...
