In the current study, effects of different post-processing methods, including heat treatment (HT) and electro-chemical polishing (ECP) as well their combination on surface texture, porosity, microstructure, mechanical properties, rotating bending fatigue behavior U-notched laser powder bed fused AlSi10Mg specimens were comprehensively investigated. addition, to better understand applied methods sensitivity notched specimen near-surface defects, finite element analysis was performed. Chemical...
This study investigated the fully reversed (R = -1), strain-controlled low cycle fatigue behavior of laser powder bed fused Haynes 282 at temperatures ranging from -195 to 871°C and strain amplitudes 0.010 0.005 mm/mm. By comparing behaviors hot isostatically pressed (HIP) specimens in machined surfaces (HIP/M) Non-HIP ones un-machined (Non-HIP/UM), combined effect surface condition isostatic pressing was analyzed discussed. The Non-HIP/UM showed shorter lives compared HIP/M 649°C, which...
Abstract Surface roughness of additively manufactured metal parts has significant impacts on the part’s performance (e.g., fatigue resistance) and poses a roadblock to wider adoption additive manufacturing. This work aims show that, in some cases, it is possible estimate depth deepest valley an part with relatively high accuracy using either only line measurements from contact profilometer (and limited areal scans used for calibration) or optical scanners considerably smaller area same...
This paper presents an analytical model of energy consumption for Direct metal laser sintering hybrid milling (DMLS-HM) additive manufacturing (AM) stainless steel 316L. The is used to quantify during production a defined geometry with DMLS-HM process and compared in electron beam melting (EBM) conventional machining (CM). solid-envelope ratio (α) was eco impact the three processes on different models. Gabi database other published literature were establish primary material shaping...
Recent advancement and research efforts in additive manufacturing (AM) have made it a promising technology to fabricate nickel-base superalloy parts near net shapes. IN625 IN718 are the commonly used superalloys elevated-temperature applications aerospace energy sectors. However, fatigue performance of additively manufactured components often depends on defects like porosity, micro-cracks, lack-of-fusions, etc. In addition, presence columnar grains residual stresses also affects their...
The unique layer-by-layer manufacturing strategy and near-net shaping capability of Additive Manufacturing (AM) make it a promising technology for Ni-superalloys components, where their typical service conditions demand complex shapes impose significant production costs due to the alloys' poor machinability. In this work, room temperature mechanical behavior several Ni-superalloys, including Hastelloy X, Inconel 718, 625, were investigated properties/performances compared. test specimens...
Abstract BackgroundAdditive manufacturing of metallic materials, a layer-wise method, is currently gaining attention in the biomedical industry because its capability to fabricate complex geometries including customized parts fitting patient requirements. However, one major challenges hindering full implementation additively manufactured safety-critical applications their poor mechanical performance under cyclic loading. This study investigated both quasi-static bending properties (bending...
This paper empirically quantified polyflake deposition repair compared to alternative thermal spray techniques specifically when applied 1045 steel shaft. Polyflake is a composite of c-glass flakes and high-performance modified resin that can substantially protect ferrous non-ferrous surfaces. In the reclamation defective or damaged metal structures by engineering materials, using metals ceramics are commonly favored over their counterparts due versatility type material utilized. However,...
