Gibson considered the cancellous bone as the cellular structure with three-dimensional cellular materials, and studied the relationships between the relative density and relative Young's modulus, relative density and relative compressive strength [1,2].
Recently, the digital speckle correlation method (DSCM) has shown its special merits in deformation measurement of materials and structures, such as being non-contact, simple optical setup, no special preparation of specimens (just spraying on the surface in the experiment) and no special requirement for the test environment, no sensitivity to the illumination and vibration[3,4,5].

Material property In the analysis, exhaust manifold uses compacted graphite iron RuT300.
Material and structure improvement In choosing material, the original cast iron usually used for the engine exhaust manifold can be changed into Si-Mo ductile iron which can work normally under high temperature.
Conclusion Simulated the working environment of auto engine exhaust manifold using finite element software ANSYS, calculated the temperature distribution of the manifold under steady-state thermal field; Through the thermal stress analysis, found the region most prone to have thermal stress centralization and fracture, conducted the failure analysis, found the reason of failure, gave corresponding solutions like improving structure and improving connecting materials.

SPCI9-2010 Egypt New Application of High Niobium Cast Iron as a Grain Refiner for Stainless Steels Hayato Sakaki1, Masayuki Mizumoto2 , Takeshi Ohgai3 and Akio Kagawa3,a 1 Graduate School, Nagasaki university, Japan 2 Department of Materials Science and Engineering, Iwate University, Japan 3 Department of Materials Science and Engineering, Nagasaki University, 1-14 Bunkyo-machi,Nagasaki 852-8521, Japan a email : akagawa@nagasaki-u.ac.jp Keywords: High niobium cast iron, Grain refinement, Niobium carbide, Stainless steel Abstract.
Introduction Grain refinement is a well-known strengthening mechanism for metallic materials.
Mechanical properties, such as hardness, tensile strength and low cycle fatigue property, are improved by decreasing the grain size of materials [1-4].
This is a preferable mechanism because it is capable to improve mechanical properties without a significant change in the chemical composition of the materials.

Setting the feature of material: According to the structural parameters, the material of XH2320 Gantry Milling machine column is HT250.
It aims at using minimum material to get the best function of the structure.
In the deep red area where the pseudo-density ρ≈{TTP}8776 1, the material should be kept; in the deep blue area where the pseudo-density ρ≈{TTP}8776 0, the material should be removed.
