Analysis of the thermal properties of magnesium alloy with the addition of noble and rare‑earth elements

The study of the thermal properties of magnesium alloys is crucial for several reasons, particularly in their applications across the aerospace, automotive, biomedical, and electronics industries. Thermal analyses allow the determination of phase transformation temperatures and thermal stability, which indirectly indicate the temperature range in which the alloy maintains its structural and mechanical properties. Differential scanning calorimetry (DSC) will enable us to study phase transitions, e.g., melting, crystallization, or the formation of reinforcing phases. This work aims to produce and characterize biodegradable metal materials based on magnesium with noble metal (silver) and rare-earth (erbium) additives using powder metallurgy techniques. The purpose of adding additives in the form of noble metals and rare-earth elements to the alloy is to create a specific structure, ensuring optimal mechanical and anti-corrosion properties. Particle analysis was performed, including the composition, size, shape, and distribution of particles in the prepared alloy. The particle size distribution in the alloys was also determined using laser particle size measurement. The thermal characteristics of the powders were investigated using differential scanning calorimetry (DSC).
