Overlapping melting trajectories and partially-melted powders result in poor surface morphology high roughness values (Ra = ~13.34 μm) of selective laser melted (SLMed) Ti6Al4V alloy. Secondary processing SLMed components is thus an essential finishing operation to produce functional parts precision engineering. This paper investigates the effects scanning strategies (0°, 67.5° 90° schemes) machining surfaces (top front surfaces) on performance alloy milling, compared with that annealed ASTM...
With the prosperity of laser powder bed fusion (LPBF) technology, post-processing tends to be increasingly attractive in further improving performance LPBFed parts. In this study, post-heat treatment and electroless plating were performed on 316L stainless steel investigate evolution surface topography, mechanical property corrosion behaviour. The results show that as-built part features melt tracks fine cellular substructures, which presents higher deformation resistance than cast...
Previous studies have reported significant differences in the Johnson-Cook (J-C) parameters of Ti6Al4V alloy. Thus, various serrated chip morphologies, cutting forces, and temperatures are obtained when different constitutive used for numerical simulation analyses, which decreases reliability model. Therefore, it is necessary to investigate analyze errors due J-C parameters. In this study, mechanism formation thoroughly analyzed using uniformly proportional The sensitivity, shear band...
Characterization of the mechanical properties plays an essential role in post-processing and evaluation functionality additively manufactured metallic parts. A number studies have been focused on tensile metals. However, quasi-static compression test 316L blocks with different heat-treatment conditions scanning strategies seems to be overlooked literature. This paper aims provide a comprehensive study compressive response plastic deformation SS316L fabricated by selective laser melting...
Abstract The grid blocks used in reservoir simulations typically have dimensions the order of tens or hundreds metres, whereas core data which are to generate block permeabilities a scale only few centimetres. Thus it is necessary up over several orders magnitude derive "effective" permeability distribution at scale. This commonly done by taking standard measures mean (e.g. arithmetic, geometric harmonic mean) and making ad hoc assumptions about rescaled variance. Such an approach can lead...
This study applied a laser cleaning method (dry cleaning) that is used for semiconductor elements to dental implant cleaning. The lasers in this were pulsed fiber with wavelengths of 1,064 and 532 nm. peak output, energy per pulse, density time pulse experiment, number experiments served as process variables study, the changed each experiment. As result, wavelength nm showed much higher efficiency than its counterpart. range decreased, quantized increased reflection rate titanium decreased;...
