Laser Surface Engineering of Magnesium Alloys: A Review
This temperature was higher than the melting point of Al 2 O 3 in all processing conditions, resulting in melting and subsequent reformation of Al 2 O 3 during solidifiion. However, the samples processed with 84 mm/s (highest scan speed among investigated parameters) retained some primary Al 2 O 3 particles along with the major portion of reconstituted (melted and resolidified) Al 2 O 3 in

Mag-Thor - Wikipedia
Another concern for the thoriated magnesium alloys is the low melting point and rapid oxidation of the metal. This can result in dangerous flash fires during the production of the alloys. Additionally, thorium-free magnesium alloys have been developed that exhibit similar characteristics to mag-thor, causing currently used magnesium-thorium alloys to be cycled out of use.
High Melting Point Metals
Metal with High Melting Point – Top 2. Rhenium (Re) Rhenium is a silver-white metal with the second highest melting point (3180 °C) after tungsten and has the highest boiling point. Commercial rhenium is generally powdered and can be pressed or sintered into a high-density solid in vacuum or hydrogen, with a density of more than 90% of the metal state.
Methodology for In Situ Microstructural Characterisation …
Important properties of magnesium alloys for engineering appliions are high specific strength and high internal dumping values, while biocompatibility, biotoxicity and biodegradability open them the possibility to be used for biomedical appliions.
Evaluation of material properties and design …
However, different values were identified as a function of alloy composition, depending on specific melting point of the alloy (experimentally measured by Differential Scanning Calorimetry (DSC)). The samples were strained in compression down to half of their original height (50% strain) and their flow stress curve was recorded as a function of strain.

Magnesium has a relatively low melting point and a thermal expansion coefficient of approximately 25 to 26.9 (10-6 mm/(mm C)). Most magnesium alloys are dimensionally stable to about 200° F, although thorium, cerium and zirconium alloying elements are added to increase its yield strength at working temperatures of up to 700° F.
