“…Magnesium and its alloys are considered leading metallic materials for bio-degradable applications due to a combination of biocompatibility, corrosion rate, and mechanical properties. Recent papers reviewed the advances in the general use of magnesium [1], the progress in in vivo studies [2] and the use of magnesium for bone repair and regeneration [3]. Scaffolds, which are porous implant structures, display great potential for tissue regeneration [4] and orthopedic applications [5].…”

Reports in the literature show that severe plastic deformation can improve mechanical strength, ductility, and corrosion resistance of pure magnesium, which suggests good performance for biodegradable applications. However, the reported results were based on testing of small samples on limited directions. The present study reports compression testing of larger samples, at different directions, in pure magnesium processed by hot rolling, equal channel angular pressing (ECAP), and high pressure torsion (HPT). The results show that severe plastic deformation through ECAP and HPT reduces anisotropy and increases strength and strain rate sensitivity. Also, scaffolds were fabricated from the material with different processing histories and immersed in Hank’s solution for up to 14 days. The as-cast material displays higher corrosion rate and localized corrosion and it is reported that severe plastic deformation induces uniform corrosion and reduces the corrosion rate.

“…The current trend in the automotive, aerospace, nautical and other similar industries is primarily a decrease in material consumption and indirectly a reduction in the mass of these means of transportation. In this respect, today, the so-called lightweight materials such as high-strength steel, aluminium, composite materials and the use of magnesium are increasingly emerging as construction materials [1] to [3]. However, due to the different properties of these materials their joining with the traditional welding process is not possible.…”

In the development of new joining technologies, incorporation of mechanical joints in computer analyses for the evaluation of structures can be carried out by a practical, simplified mechanical joint model. Here, two most frequently used joining technologies were analysed, a self-piercing rivet joint and a clinch joint. Physical tests of static load capacity of the joints were performed and numerical models for simulations were set-up. An optimization method was designed for estimating the material parameters of the mechanical joint for the needs of numerical analyses. For optimization purposes during the plan of experiments, a range of possible parameter values was investigated using a response surface method, results of simulations, results of physical tests and a genetic algorithm. The results of simulations using the optimal values of the material parameters are comparable to the experimental observations for the both joints.

“…As the lightest structural metal in industrial applications, magnesium alloys have been intensively investigated due to their contributions in energy conservation and environment protection [1][2][3][4]. Owing to their hexagonal close-packed (HCP) lattice structure, the easy slip systems in Mg alloys are insufficient to support the stable plastic deformation at room temperature [5][6][7][8][9][10].…”

Rare-earth-containing Mg alloys are a group of widely investigated alloys due to the disperse nano-sized precipitations formed during heat treatment. The underlying formation and strengthening mechanisms of precipitation is critical for their industrial applications. In this work, we systematically studied the evolution of precipitations in a Mg-10Gd alloy, based on the atomic-scaled TEM and HAADF-STEM observations. Especially, the in-depth transition mechanism from G.P. Zone to β”, β’, βT and βM is proposed, as well as their relationships with mechanical properties. It is found that blocking effect of precipitations improves the strength significantly, according to the Orowan mechanism. The elliptic cylinder shaped β’ phase, with a base-centered orthorhombic lattice structure, provides significant strengthening effects, which enhance the hardness and ultimate tensile strength from 72 HV and 170 MPa to 120 HV and 300 MPa.
