Due to their capability of fabricating geometrically complex structures, additive manufacturing (AM) techniques have provided unprecedented opportunities produce biodegradable metallic implants—especially using Mg alloys, which exhibit appropriate mechanical properties and outstanding biocompatibility. However, many challenges hinder the fabrication AM-processed Mg-based implants, such as difficulty powder preparation, splash, crack formation during AM process. In present work, components...
Magnesium (Mg) alloys that have both antibacterial and osteogenic properties are suitable candidates for orthopedic implants. However, the fabrication of ideal Mg implants bone repair remains challenging because it requires with interconnected pore structures personalized geometric shapes. In this study, we fabricated a porous 3D-printed Mg-Nd-Zn-Zr (denoted as JDBM) implant mechanical using selective laser melting technology. The JDBM exhibited cytocompatibility in MC3T3-E1 RAW267.4 cells...
As a universal casting Mg-RE alloy, Mg-6Gd-3Y-Zr (GW63K, wt.%) alloy exhibits superior strength-ductility synergy and holds significant potential for engineering applications. In this study, the GW63K is produced using laser powder bed fusion (LPBF) additive manufacturing (AM) process first time. The printability, microstructure characteristics, post-heat treatment conditions of are systematically investigated. as-built samples demonstrate high relative densities exceeding 99.6% exhibit no...
This study evaluates the heat treatment effects on microstructural and mechanical properties of A357 alloy. Solution treatments performed at 540 °C for 6, 8, 10 h represent identical microstructures show that eutectic phase is partially dissolved into matrix, resulting in Si particles similar shape size. Contrarily, parameters influence Mg2Si precipitates length rather considerably; 8 solution treated-peak aged condition produces smallest sized needle-shaped βʺ contributes principally...
In order to verify the feasibility of producing Mg−rare earth (RE) alloy by selective laser melting (SLM) process, microstructure and mechanical properties Mg−15Gd−1Zn−0.4Zr (wt.%) (GZ151K) were investigated. The results show that fine grains (~2 μm), secondary phases weak texture, observed in as-fabricated (SLMed) GZ151K Mg alloy. At room temperature, SLMed has a yield strength (YS) 345 MPa, ultimate tensile (UTS) 368 MPa elongation 3.0%. After subsequent aging (200 °C, 64 h, T5 treatment),...
The effects of different Zn addition (0, 0.2, 0.5, 1.0 wt%) on the microstructure and mechanical properties cast Mg–1Nd–1Ce–Zr alloy in as-cast, solution-treated 200 °C peak-aged conditions were studied. Precipitates are significantly modified by addition. In Zn-free alloy, disk-shaped prismatic precipitates point-like main strengthening phases. When 0.2 is added, refined very fine basal form additionally. 0.5 become phase. Further increasing to 1.0%, only spare exist. has highest strength...
Polycaprolactone (PCL) is widely used in bone tissue engineering due to its biocompatibility and mechanical strength. However, PCL not biologically active shows poor hydrophilicity, making it difficult for new bones bind tightly surface. Magnesium (Mg), an important component of natural bone, exhibits good osteo-inductivity biological activity. Therefore, porous PCL/Mg scaffolds, including pure PCL, PCL/5%Mg, PCL/10%Mg, PCL/15%Mg, were prepared elucidate whether the structure scaffolds...
