The plastic deformation resistance of the material is one of the key factors that directly affects the safe operation of equipment and insurance of the plastic deformation during thermal processing[2].
Strengthening (hardening) and softening (recovery and recrystallization) of metallic materials takes place in the process of plastic deformation.

Some stable complex substances can be formed by a chiral stationary phase (CSP) and isolate material.
When hydrogen bonding, dipole - dipole interactions and π-π seize dominant position, the isolate material can be separated from CSP.

Recovering Gold from a Gold-bearing Pyrite by flotation and chemical process Qing Li1,a,Baoliang Ge1.b,Jie Liu1,c,Chao Zhu1,d 1Faculty of Land Resource Engineering, Kunming University of Science and Technology, Kunming 650093, China a735406880@qq.com, b411977506@qq.com c527245266@qq.com,d231652466@qq.com Keywords: gold-bearing pyrite; flotation; cyanide leaching; regrinding Abstract: The ore assays 2.5g/t Au, 23.4% S and 56.6% Fe.
The gold can be found as metal or alloy(silver，copper, bismuth), as a distinct mineral in combination with tellurium ,or it can be contained in carbonaceous material, pyrite, marcasite, arsenopyrite and siliceous gangue[1], which are difficult to recover.
Materials and Methods Representative ore samples were taken from Sichuan, China.

Recently, synthesis technology of ultra-fine nano-structured materials can be attained by utilizing ultrasonic radiation because it is able to provide high frequency clean energy to prevent the agglomeration [4].
The shift could be due to increase of the surface area possibly resulting from the size decrease of material.

Introduction Uniform Droplet Spray (UDS) process was first proposed by Yim at 1996, in which molten metal droplets are ejected through the nozzle to the inert gas environment by applying the static pressure on the bulk liquid material in the generator, and then deposit onto a movable substrate to fabricate 3-D prototypes [1].
It is reported that UDS rapid prototyping has been used in biomedicine, micro-structure and graded materials fabrication, and repair of spaceflight structures.
