Effect of heat treatments on the microstructure and corrosion behavior Al–Mn–Mg–Sc–Zr alloy fabricated by laser powder bed fusion (LPBF) were systematically investigated. The results demonstrate that 300 °C/5 h heat-treatment doesn't alter typical bimodal grain distribution LPBF-fabricated alloy. However, grains at molten pool boundaries experience a significant growth after 500 treatment, narrowing gap size between fine-grain (FG) region coarse-grain (CG) region. It is also found have an...
Al-Li alloys are extensively utilized in the field of aerospace due to their low density and high specific strength. However, laser powder bed fusion (LPBF) processed still encounter challenges because hot cracking Li element ablation. In this study, a TiC nanoparticle modified Al-Mg-Li alloy is developed for LPBF process. Full dense printed can be obtained. The presence nanoparticles melt pool effectively increased viscosity Al liquid, leading reduction metal vaporization liquid spatters,...
For the orthopedic application, promising biodegradable magnesium alloys gained increasing attention. In order to improve interface bonding strength and corrosion resistance of alloys, a novel ultrasonic aqueous synthesis approach was performed produce hydroxyapatite coating on alloys. The effect time composition, microstructure, HA coated were investigated. A dense crack-free synthesized by only cavitation for 1 h in solution containing Ca2+ PO43− ions constituted bamboo leaf-like staggered...
In iron-based alloys, a series of micro-segregation is caused by localised slow cooling due to large-size configurations, and the regulation solute-atom grain-boundary segregation has far-reaching effects on structural properties polycrystalline materials. Here, researchers report that ultrafast techniques are utilised in conventional casting processes provide control grain boundary elemental segregation. alloys with low oxygen nitrogen, interaction force between trace nonmetallic impurity...
In order to meet the clinical application requirements of biodegradable materials in orthopedic surgery field, novel Mg–3Zn–0.5Zr/ xHA ( x = 0, 0.5, 1 and 1.5 wt%) composites have been developed by melting under mechanical stirring heat extrusion route. The thorough examination on effect nano-hydroxyapatite (nano-HA) particles microstructure, properties corrosion resistance Mg–3Zn–0.5Zr alloy was carried out. results indicated that gelatin-coated nano-HA could more uniformly distribute...
High strength Al alloy development is the key technique to additive manufacturing (AM) applied on lightweight of aerospace, automotive and military industry. Unlike conventional wrought Al–Si eutectic alloys available for AM process, new developed can be improved by in situ or additional nano-precipitated phase. This paper presents an overview high including metallic additives, such as Zr, Sc, Mn, Cu, etc., nanoparticle ceramics (TiB 2 , TiC, LaB 6 TiN) well carbon nanotubes (CNTs). The...

Corrosion behavior on different planes of laser powder bed fusion (LPBF) Al-Mn-Mg-Sc-Zr alloy was investigated based microstructure characterization coupled with corrosion measurements. The results demonstrate that localized preferentially occurred at the molten pool boundaries both planes, where distribution abundant micro-cathode Al 3 (Sc,Zr) precipitates act as predominant role. In addition, higher residue stress could also contribute to acceleration corrosion. contrast, micro-anode 6...
