Degradable magnesium alloys are new materials for implants used in orthopedic and trauma surgery. The aim of this study was to investigate the influence of degradable magnesium alloys on the function of dendritic cells (DC) as these cells represent the major antigen presenting cells of the body.
13/8/2020· Nickel processing - Nickel processing - The metal and its alloys: Pure nickel possesses a useful coination of properties, including corrosion resistance, good strength, and high ductility, even at extremely low temperatures. It also possesses useful electronic properties and special magnetic properties. Nickel is a particularly good alyst for the hydrogenation of unsaturated compounds in
Owing to their excellent strength-to-weight ratio and low density, magnesium alloys have the potential to significantly reduce the weight of automobiles leading to decreased emissions and greater range for electrical vehicles. However, the practicality of magnesium alloys for automotive and aerospace appliions is severely hindered by their poor corrosion resistance in aqueous environments

Magnesium ions are essential to the basic nucleic acid chemistry of life, and thus are essential to all cells of all known living organisms. Plants have an additional use for magnesium in that chlorophylls are magnesium-centered porphyrins.Many enzymes require the presence of magnesium ions for their alytic action, especially enzymes utilizing ATP, or those which use other nucleotides to
Compared to many other metals and alloys and many other materials, such as carbides, ceramics and sintered carbides, aluminum and its alloys are low in strength and hardness. Aluminum is a soft, silvery metal with a face-centered cubic crystal structure, a hallmark of ductile metals. Its softness makes it somewhat difficult to prepare but the alloy is not sensitive to problems that plague
Magnesium alloys have great potential as biodegradable materials and have attracted much attention in recent years. Much effort has been expended to improve the properties of biodegradable alloys.

Development of ductile magnesium alloys is key to their use in reducing the weight of vehicles and other appliions. Wu et al. tackle this issue by determining the underlying mechanisms in unprocessed magnesium alloys. Dilute amounts of solutes enhanced certain ductility-improving mechanisms over ones that cause brittle fracture. From this, the authors developed a theory that may be helpful
Brasses are copper zinc alloys. In general, they have good strength and corrosion resistance, although their structure and properties are a function of zinc content. Alloys containing up to approximately 35% zinc are single phase alloys, consisting of a solid solution
Bolt-load retention properties were examined as a function of time (at least 100 hours), temperature (150 and 175 C) and initial bolt preload (14 to 34 kN). We have also investigated the creep properties of these alloys from 150 to 175 °C and under initial applied stresses between 20 and 185 MPa.
Magnesium (Mg) 5xxx - The addition of magnesium to aluminum increases strength through solid solution strengthening and improves their strain hardening ability. These alloys are the highest strength nonheat-treatable aluminum alloys and are, therefore, used extensively for structural appliions.
