Magnesium Dysprosium Master Alloy Description
The master alloy is used in casting and wrought magnesium alloys that incorporate rare earth elements. It is applied to improve alloy performance. The form and packaging of the products are determined by the client’s specifications. The concentration of the key rare earth metals in the master alloy is not lower than the levels required by the client.
Applications of Magnesium Dysprosium Master Alloys
Rare earths (RE) have been successfully alloyed with Mg. The addition of rare earth (RE) elements refines the grain structure and reduces anisotropy, thereby enhancing the ductility of Mg alloys. In addition, the rare earths produce a dispersion of thermally stable precipitates with melting points exceeding 620 °C, which compares favourably to the precipitates in the Mg-Zn system that melt at approximately 340 °C and exhibit poor thermal stability, resulting in a tendency towards hot cracking.
