Journal of Physics Conference Series Volume 891 2017
The reactor retort is a cylindrical vessel with a radius of 0.75 m and a height up to 4 m filled with liquid magnesium at a temperature of 850°C. The exothermic chemical reaction on the metal surface cooling of the side wall and heating of the lower part of the retort cause strong temperature gradients in the reactor during the process.

Sep 01 2017 · As shown in Fig. 3(a) the generator (GEN) is heated through solar collectors subjected to varying solar radiation levels. Constant heat supply can only be maintained by either running an auxiliary heating unit or through thermal storage system. The heat then flows through the dephlegmator (DEPH) where the water is condensed from the weak solution vapor and goes back to the generator.

aluminum-lithium alloys of the 8xxx series. For the cast alloys this includes the aluminum-copper alloys (2xx.x) some of the aluminum-silicon copper and/or magnesium alloys (3xx.x) and the aluminum-zinc alloys (7xx.x). One rather disappointing property of high-strength aluminum alloys is their fatigue per-formance. Increases in static

Corrosion behavior of B206 aluminum-copper casting alloy
Aluminum-copper casting alloys have relatively high strength and hardness fatigue and creep resistances and good machinability all of each are dependent on the copper content of the alloy. The Al-Cu casting alloy (4.2-5.0 wt Cu) known as B206 is a potential candidate material for use in marine applications where good mechanical properties and high strength to weight ratio is desired
