Experimental procedures
In this study, AM50A alloy was selected since it was popular die-casting alloy of simple chemical
composition (Mg-5mass%Al).
Elongation of AM50A alloy extruded at 348K is 6.7%, which is about one third of die cast value (18.2%). 0 100 200 300 400 500 0 5 10 15 20 25 Extrusion ratio, R Tensile strength, σ0.2 and σUTS / MPa 0 10 20 30 40 50 Elongation (%) σ0.2 σ El. 0 100 200 300 400 500300 400 500 600 Extrusion Temperature, T/K Tensile strength, σ0.2 and σUTS/MPa 0 10 20 30 40 50 Elongation (%) σ0.2 σUTS El.
Especially, magnesium alloys based on Mg-Al system (AM50A, AM60B) and Mg-Zn-Zr-RE system (ZE41A, EZ33) has excellent strength.

Jensen and Sørensen [3] found an over capacity of 570% in installed power and a 420% over capacity in annual energy demand for four buildings in Narvik, Norway. [3,4,5]; Riise et al 2006; Riise et al. 2009, have also demonstrated that merging, co-ordinating and optimizing stand-alone systems into a local heating network can be an alternative to developing new district heating systems with only one mutual heating central.
Later, Riise et al [7] expanded the expression to also include the distribution heat loss.
Skartveit et al [12] claims that calculation of building’s energy performance should not be performed from long-term average of weather data, but rather by using generated collection of weather data representing the climate for the site in question.

Fan et al [9], in 2015 also conducted a reseach about aluminum as an anode for Al-air battery.
Significant portions of the As-cast microstructure display an irregular pattern of α-Al and Al2Cu.
As stated by Ran et al. [5], the white lamella lines represent α-Al, while the black lamella lines represent Al2Cu.
