Optimization of the multi-layer die for support shaft Xiaohui Huang 1, a Min Zhang 2, b Yao Wang 3, c Xinhai Zhao 1,d 1Department of Material Science and Engineering, Shandong University, Shandong, Jinan, 73 Jing10 Road, P.R.
Apart from the node forces, the initial variable value R in optimization can be determined from the deformation analysis. 4Cr5MoSiV1 and 20Cr, equivalent to AISI H13 and AISI 5120, are designated as the materials of die and workpiece.
H13 and 5140 are traditional tool materials, and thus the allowable stresses were specified as constraints in the optimization to avoid the die failure [3, 7].

Introduction Fe-Ni binary alloys are one of the mostly wildly used soft ferromagnetic materials, due to its high permeability under the weak magnetic field[1].
Experimental detail 99% pure Fe powder, 99.9% pure Cr powder and 99% pure Ni powder were used as starting materials.
The bowl and mill ball materials were hardened chromium steel.

The X-ray diffractogram of the LM company galvanic sludge shows a deformed background, indicating a high fraction of amorphous material in the sample.
One of the potential uses of this hazardous waste is a raw material to produce environmentally sensitive and useful materials [8, 9].

Saegusa[2] pointed out in the theory of organic - inorganic hybrid material that the hybrid composite was the mixture of inorganic and organic materials of subtler level than general composite materials (namely, the nanometer level).
With the development of organic-inorganic composite materials, the new composite of epoxy resin and inorganic materials has become a trend.
Rong et al. illustrated that the overall material durability depended on powder dispersion and the heterogeneity of the micro-structure of filling materials [9].
Experimental Materials.
Note that all the purchased materials were used as-received without further purification.

At the same time, many researchers have put into action and new biomass materials [4], new products [5,6], processing machinery [7] were developed.
Mechanical Parameters Testing of Tableware Materials.
The elastic modulus and Poisson’s ratio were calculated and the force-displacement curves of tableware materials were drawn by computer automatically.
The higher strength of materials was consistent with the stronger compression performance.
