Experimental material and method Experimental material is X80 pipeline steel, whose chemical compositions and mechanical property are following in table 1.
Thus the composition of inclusions inducing nucleation of intra-granular ferrite depends on deoxidation and desulfidation alloyed elements in the steel and welding materials.

Experimental Material and Method The test material was steel 40Cr, initially quenched and tempered.
The raised material with repeated plastic deformation caused by the friction leads to work hardening, cracking, spalling and then generated chips.

(1) Absorbing materials Absorbing materials can absorb incident electromagnetic wave and consume electromagnetic energy through energy transform or make electromagnetic wave disappear because of interference.
It is a mature absorbing material and attracts much research.
With the information security becoming more and more important, electromagnetic interference and anti- electromagnetic interference has became an important part of science research.

Mehregany Department of Electrical Engineering and Computer Science Case Western Reserve University, Cleveland, Ohio 44106, USA Keywords: LPCVD, Poly-SiC, Young's modulus, Residual stress, Bulge test Abstract: Polycrystalline silicon carbide (poly-SiC) thin films were grown in a large-volume, lowpressure chemical vapor deposition (LPCVD) furnace using dichlorosilane (SiH2Cl2) and acetylene (C2H2) precursors.
Introduction SiC is an exceptionally attractive material for microelectromechanical systems (MEMS) due to its outstanding mechanical, chemical and electrical properties.
Currently, polysilicon is the dominant material in MEMS owing to high throughput deposition processes that yield films with favorable electrical and mechanical properties, thus setting the standard for materials such as SiC.
Poly-SiC films deposited simultaneously on both sides of the wafer 2 Title of Publication (to be inserted by the publisher) needed no additional etch mask material since the backside poly-SiC film could be patterned by RIE into etch masks.

Table 2 shows the material properties of welded metal bellows.
So, the material, the quality and the welding technology should be considered in the welded metal bellows designing.
