There are still a large number of interesting and important unsolved phenomena in natural scie, Goal of this work is to explore and adapt the new and un-conventional ways of manufacturing advance materials. .............................................. ............................................................................................................................84. Magnesium alloys have many advantages as well as it also has some disadvantages also. nces, i.e., in biology, in physics, and in engineering, which can be explained only if structural instabilities, such as buckling of plates and shells, are carefully taken into account. Using Density Functional Theory simulations, we present expressions of the energy of magnesium-aluminum binary solid solutions as a function of concentration, strain and temperature. M. M. Avedesian and H. Baker, ASM International, 1999. PDF | The need for light-weight materials, especially in the automobile industry, ... Magnesium alloys have low density, and thus are commonly used in the aerospace or automotive industries.

Finally, we report the influence of thermomechanical loads on the growth of precipitates, where we observe compressive strains along the $c$ axis promotes growth, whereas strains along the $a$ and $b$ directions do not influence the growth of precipitates. Hiermit können Forderungen gerade von Seiten der Automobilindustrie nach schadenstoleranten, besser verformbaren Magnesiumbauteilen begegnet werden. The strength of these alloys is improved by forming a solid solution where 11.5 atomic percent Al are soluble in the Mg matrix at 437°C [30, 31]. H. Singh Tathgar, T.A. The literature on grain refinement of magnesium alloys is reviewed with regard to two broad groups of alloys: alloys that contain aluminum and alloys that do not contain aluminum. .....................................................................................................
