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.

In selecting materials for corrosive sour oil field environments, the materials of choice must be reliable and cost-effective.
So materials selection for Oil Country Tubular Goods can be a complex task involving high financial and safety risks.
It can be seen from the table.1 that the contents of Ni, Cr, Mo, Cu were the main difference between these two materials.

Plate and strip hot rolling lines are equipped with water cooling systems used to control the deformed material temperature.
The suitable cooling rate and the deformed material temperature can be determined based on numerical simulations.
In the industry the combination of different systems can be found depending on many factors (technology, material, geometry, etc.).

Researches show that the giant debris flow in Hongchun gully started from Ganxipu lateral ditch in the upstream, the materials collected and dam-broke, It collected the material sources of the main ditch, crushed into Minjiang River, joined with the material sources of Shaofan gully debris flow in the river-upstream, blocked river and became dam lake.
A large number of landslide accumulations are distributed on both gully sides and in the gully, which provides a lot of material sources for debris flow.
