Study to Microstructure and Mechanical Properties of Mg Containing High Entropy Alloys Rui Li1, a, Jiacheng Gao1, b, Ke Fan 1, c 1 College of Materials Science and Engineering, Chongqing University, Chongqing City, 400030, China a email:cqu_cos@yahoo.com.cn, bemail:gaojch@cqu.edu.cn, cemail:fanke_524@163.com Key words: high entropy alloy; quasicrystal; microstructure; mechanical properties Abstract: In this paper, alloys with compositions of Mgx(MnAlZnCu)100-x (x: atomic percentage; x=20, 33, 43, 45.6 and 50 respectively) were designed by using the strategy of equiatomic ratio and high entropy of mixing.
The alloy samples were examined by microhardness tester, XRD, SEM, thermal analyzer and testing machine for material strength.
Mg is considered to be one of the next generation light metal engineering materials; the studies of improving mechanical properties of Mg alloys are popular in the world nowadays.

Besides, the non-continuity of structural materials and the variety of geometrical conditions cause the thermal bridge problem of multi-dimensional heat transfer.
However,it needs the materials' thermal conductivities close to each other.
With the development of energy-saving in buildings, many efficient materials are gradually used in the constructions.
The thermal conductivity of it is about dozens of times to that of the structures materials, which is not accurate of the results with this method and is not favor to the proper evaluation of the heat insulation properties of this material.
