Introduction In deep drawing process, the material deformation of rectangular box part is inhomogeneous, which is large in the rounded part and little in the straight edge of the part.
And the material properties were taken as follows: the material is DQ steel, thickness=1.0mm, Young modulus E=2.07GPa, Poisson’s ratio =0.28, anisotropy coefficient =1.66，=1.23，=2.10.
In the deep drawing process of rectangular box part, the fracture and wrinkle objective reflect the same importance of material forming.

Materials Aeolian sand.
When the environmental material flyash is added into the mix mortar, the activated silicon oxide and activated aluminum oxide in the flyash will react with the calcium hydroxide in the mortar and will generate more and more cementitious materials with the age increasing, enhancing the physical and mechanical properties of hardened mortar.

Four material combinations of gears were tested: wheel and pinion uncoated, wheel and pinion coated, wheel coated and pinion uncoated as well as wheel uncoated and pinion coated.
For many engineering materials, further improvement of their properties through a modification of their microstructure, chemical composition, phase composition, and oil formulation is practically impossible [1].
The results from pitting tests obtained for gear material combinations with MoS2/Ti coating are summarised in Figs. 4 and 5.

Introduction Inorganic polymers are cementitious materials using industrial by-products as the main raw material, excited by properly configured activator solution.
A research by En Wang from Beijing University of Science and Technology [2] indicated that the different raw materials (such as slag, and fly ash and the kaolin) and different region perform differently under alkali-activator.
Reference to the experience of ordinary cement and concrete, adding appropriate admixture and mixed materials to inorganic polymer material is a good solution.
