In this work, the microstructure and degradation properties of a novel metal matrix composite composed Mg with addition 1 vol. % hydroxyapatite nanopowder (Mg + vol nHAp) were evaluated. The composites in form discs produced using spark plasma sintering (SPS) subjected to plastic deformation modified extrusion technique an oscillating die located at end extruder (called KoBo), which enables without preheating initial billet. was analyzed optical scanning electron microscopy (SEM) subsequent...
This study describes the corrosion resistance of extruded, and extruded with post-processing annealing, Mg–7.5Li–3Al–1Zn alloys. The results demonstrate that extrusion at 350 °C an speed 0.5 s−1 does not lead to full recrystallization alloy, material still exhibits a dendritic microstructure. annealing triggers microstructure transformation, relative composition alloy changes. ratio β(Li) α(Mg) in was 29–71%; after amount increased, annealed 35–65%. Corrosion testing shows 3.5 wt% NaCl...
The microstructure-dependent corrosion resistance of dual structured fine-grained Mg-7.5Li-3Al-1Zn has been investigated. alloys were extruded using extrusion with a forward-backward rotating die (KoBo, newly developed SPD method) at two different ratios. microstructures formed in the characterized, and influence grain refinement on was analyzed. For (α + β) Mg-Li alloys, higher ratio led to more intensive refinement; however, this relationship did not improve their chloride-containing...
This study describes the role of bimodal grain size distribution on corrosion resistance Mg–4Li–3Al–1Zn (LAZ431). The coarse-grained microstructure formed in alloy after extrusion was compared with observed additional annealing. observations show that extruded alloy, as well one subsequent annealing, were composed α(Mg), MgZn2, coarse AlMn-rich precipitations, and nanosized AlLi, Mg17Al12 Li2MgAl. annealing caused transformation triggered anomalous inhomogeneous growth which increased ratio...
In this study, powder metallurgy methods were used to fabricate Mg-7.5Li-3Al-Zn alloys from repowdered extruded alloys. Extruded powdered using ultrasonic atomization, and then laser bed fusion (LPBF) pulse plasma sintering (PPS) consolidate the bulk materials. A comparison of properties fabricated with those a conventionally one was carried out that characterized microstructure corrosion resistance. When compared their counterpart, LPBF PPS materials exhibited refined microstructures low...
Abstract The development of powder metallurgy methods in recent years has caused traditional casting to be replaced many industrial applications. Using such methods, it is possible obtain parts having the required geometry after a process that saves both manufacturing costs and time. However, there are material issues decrease functionality these including mechanical properties anisotropy greater susceptibility cracking due chemical segregation. main aim current article analyze depth for two...
Abstract Inconel 718 is a precipitation hardenable nickel-iron based superalloy. It has exceptionally high strength and ductility compared to other metallic materials. This due intense of the γ’ γ” strengthening phases in temperature range 650-850°C. The main purpose authors was analyze aging process obtained accordance with AMS 5596, its effect on mechanical properties. Tensile hardness tests were used evaluate properties, initial after reheating, as function time respectively ranges...

Samples were tested for dimensional accuracy using 3D scanner. Then, samples subjected to rolling. microstructures DMLS as-cast analysed scanning electron microscope. properties determined in static test. Microhardness measurements also performed. Based analysis...
The influence of different types precipitation on the corrosion behavior was investigated in three aluminum-siliconmagnesium alloys. microstructures alloys were studied through optical (OM) and scanning electron microscopy (SEM). structures consisted an α-Al solid solution matrix, Si eutectic crystals, secondary phases AlFeSi AlMgFeSi (Chinese script), as well Mg 2 Si. examined with use a potentiodynamic polarization test followed by SEM surface analysis. results indicate that all analyzed...
The influence of grain boundaries and fine precipitation on the corrosion behavior was investigated in two model aluminum–lithium alloys, namely (in wt%) Al–1.6Li (lithium a solid solution) Al–2.3Li form Al3Li precipitation), subjected to three different severe plastic deformation (SPD) treatments which refined microstructure alloys ultrafine size. SPD techniques used experiments were equal channel angular pressing (ECAP), hydrostatic extrusion (HE), extrusion-torsion (ET). examined using...
