Currently some biomaterials, especially Zn and Mg alloys related manufacturing methods are among important research topics due to their suitable biocompatibility, mechanical corrosion properties. alloy has been processed by Mechanical Alloying method. Hot sintering was conducted at 410°C under argon atmosphere. Resulting microstructures densities hardness test behaviors of the Zn-based were studied.Visual inspection using SEM (Scanning Electron Microscope) analyses indicates that...

The impact properties of an L-PBF 18Ni-300 maraging steel were investigated after different heat and duplex (nitriding PVD coating) surface treatments. Impact energy is almost isotropic. Contrary to expectations, not decreased by treatments, since the effect embrittlement nitriding compensated increase in austenite content. An important role played geometry notch where hardening lower than flat Charpy specimens.

This paper investigates the eect of electrical discharge machining parameters on surface roughness as an alternative method for Al/SiCp metal matrix composites produced with powder metallurgy.Current, electrode type, pulse-on-time, particle reinforcement weight ratio and voltage were used process parameters.An experimental plan (L18) was constituted by using Taguchi orthogonal design.Results experiments showed that pulse-on-time (34%) current (31.26%) is most inuencing parameters.Besides...

Currently some composite materials and related manufacturing methods especially particle reinforced magnesium matrix composites are among important research topics because of their superior properties over monolithic metals.Mg-B4Cp is the commonly used material for fabrication light-weight functional components.Wear behaviour play critical role potential application in industries such as automotive aerospace.In this study, dry sliding wear behavior manufactured by powder metallurgy with...

Abstract In this study, the influences of reinforcement volume fraction and ratio particle size to matrix on wear behaviour Al/SiC metal composites were investigated by use a model function obtained from an artificial neural network. Hardness ball-on-disc tests applied manufactured via powder metallurgy method. The results indicate that as increase, loss decreases except in two cases; first case (vol.% ≤ 7.5), rises, increases then decreases. second case, decreasing trend at high values (≥...

The axial fatigue strength of maraging steel produced by Laser Powder Bed Fusion (L-PBF) was investigated for different heat and surface treatments following were considered: Direct Aging the as-built material a duplex treatment consisting in plasma nitriding followed PVD coating. increases 40% at 107 cycles, but improvement decreases with increasing stress amplitude. is due to hard diffusion layer, which causes transition from surface-initiating failure an interior-initiating low

This study investigates the sintering mechanism of commercially pure Magnesium (Mg) using Field Assisted Sintering Technique (FAST). Powder morphologies are in a vast variety spherical to flake, as well nano fine grain powder size and mechanically milled (MM) between 0-108 hours. The MM'ed Mg particles were sintered by FAST with at 350-425℃ for 5-20min. Relative densities (93-99%) compressive strength up 369MPa obtained from FAST’ed samples depending on MM durations particle geometries which...
