Thermal expansion of magnesium and some of its alloys

Abstract

This paper gives data on the linear thermal expansion of 6 samples of cast and extruded magnesium and 11 samples of cast and extruded magnesium alloys (magnesium-aluminum and magnesium-aluminum-manganese alloys). The samples of magnesium were investigated over various temperature ranges between -183 0 and + 500 0 C. and most of the alloys between room t emperature and 300 0 C. Three types of apparatus were used in this research, and a summary of available data by previous observers on the thermal expansion of magnesium and some magnesium alloys is givel!.
