A two-step technology combined forging with superplastic forming has been developed to enhance the forgeability of semi-continuously cast AZ70 magnesium alloy and realize the application of the as-cast magnesium alloy in large deformation bullet shell.In the first step,fine-grained microstructure preforms that are suitable for superplastic forming were obtained by reasonably designing the size of the initial blanks with the specific height-to-diameter ratio,upsetting the blanks and subsequent annealing.In the second step,the heat treated preforms were forged into the end products at the superplastic conditions.The end products exhibit high quality surface and satisfied microstructure.Consequently,this forming technology that not only avoids complicating the material preparation but also utilizes higher strain rate superplastic provides a near net-shaped novel method on magnesium forging forming technology using as-cast billet. 展开更多

The highlights of major Canadian research projects of last two decades that aimed at advancing applications of magnesium and its alloys,being at the heart of lightweighting and ecological sustainability, are outlined. The research at universities, government laboratories, and other dedicated institutions, funded primarily through federal programs, was accompanied by strong activities of the industrial sector involved in designing and building the machinery for magnesium processing and production of components from magnesium alloys. The overall research directions matched the global trends of overcoming the key challenges that prevent magnesium alloys to play the major role in large-scale applications. Among industrially oriented projects the processing technologies in liquid, semisolid and solid states such as casting, twin roll casting, injection molding, rolling, extrusion, forging, and joining techniques were frequently pursued. Although the fundamental research aimed at understanding of a variety of magnesium behaviors and structural peculiarities up to nano and atomic levels, its essence spread around the inherently poor formability and high reactivity at room and elevated temperatures, including the ignition/flammability concerns.In recent years, a shift in research interests was observed and novel directions emerged such as magnesium air batteries, biodegradable alloys, additive manufacturing, and magnesium-rich high entropy alloys. The volume of data gathered in this report may constitute a base for specifically oriented assessments, analyses, and drawing conclusions. 展开更多

Reconstruction of subarticular bone defects is an intractable challenge in orthopedics.The simultaneous repair of cancellous defects,fractures,and cartilage damage is an ideal surgical outcome.3D printed porous anatomical WE43(magnesium with 4 wt%yttrium and 3 wt%rare earths)scaffolds have many advantages for repairing such bone defects,including good biocompatibility,appropriate mechanical strength,customizable shape and structure,and biodegradability.In a previous investigation,we successfully enhanced the corrosion resistance of WE43 samples via high temperature oxidation(HTO).In the present study,we explored the feasibility and effectiveness of HTO-treated 3D printed porous anatomical WE43 scaffolds for repairing the cancellous bone defects accompanied by split fractures via in vitro and in vivo experiments.After HTO treatment,a dense oxidation layer mainly composed of Y2O3 and Nd2O3 formed on the surface of scaffolds.In addition,the majority of the grains were equiaxed,with an average grain size of 7.4μm.Cell and rabbit experiments confirmed the non-cytotoxicity and biocompatibility of the HTO-treated WE43 scaffolds.After the implantation of scaffolds inside bone defects,their porous structures could be maintained for more than 12 weeks without penetration and for more than 6 weeks with penetration.During the postoperative follow-up period for up to 48 weeks,radiographic examinations and histological analysis revealed that abundant bone gradually regenerated along with scaffold degradation,and stable osseointegration formed between new bone and scaffold residues.MRI images further demonstrated no evidence of any obvious damage to the cartilage,ligaments,or menisci,confirming the absence of traumatic osteoarthritis.Moreover,finite element analysis and biomechanical tests further verified that the scaffolds was conducive to a uniform mechanical distribution.In conclusion,applying the HTO-treated 3D printed porous anatomical WE43 scaffolds exhibited favorable repairing effects for subarticular cancellous bone defects,possessing great potential for clinical application. 展开更多
