Introduction Magnesium alloys have become promising materials saving structural weight and consequently reducing fuel consumption for transportation industry due to being the lightest metal for structural applications.
Materials and Methods Finite element model The Sketch of Die and Magnesium Alloy Billets is shown in Fig.1.
In this study, the material properties for the alloy was given in Table 1.

Introduction For many years, gasket materials for many important uses have contained asbestos fibers.
However, recent concerns about the health hazards associated with exposure to asbestos fibers have resulted in prohibition of traditional asbestos fiber materials and attempts to produce asbestos-free gasket materials.
It has been used widely in manufacturing gasket materials because of its low cost and convenience of mass production.

Recycling product inventory refers to material inventory  used to reprocessing,which comes from the recycled materials after the proprecessing of splitting, cleaning , inspection and testing.
t1 t2 t3 t4 T recovered materials inventory finished products inventory Fig. 2 Variation of recovered materials inventory and finished products inventory Assumptions.In order to facilitate discussion, we make the following assumptions on the system：When the cycle are rather short, the main factors affecting market  demand is relatively stable,  so suppose marketable products market demand rate in different stage is certain.
After a preliminary classification, detection, dismantling, recycling materials are put in recovered products inventory.At the end of the cycle, they will be deal with at a one-time.
Recycling materials can be repaired to be salable and will be put in new products inventory.

So recycled concrete accord with the tide of development and has a broad development prospect as a new green material [1~4].
Experimental Design Experimental Materials Coarse Aggregate: Recycled coarse aggregate is from the waste concrete of basketball court at the Southwest University of Science and Technology and the natural coarse aggregate is from ordinary gravels, all of this is crushed by crusher and obtain continuous grading from 5mm to 20mm by artificially screening.

The composite material has been laminated, or its surface has been metalized, so it is difficult to process these monolithic materials and laminates.
In the second place, according to the characteristics of the aeroplane composite material, the cutting tool need different materials, including high-speed steel cutting tool, diamond tool, hard steel cutting tool, etc, which is described in [3,4].
