Introduction As one of the most commonly used titanium alloys, titanium and its alloys are utilized in aero-engine and airframe manufacture because of their outstanding strength to density ratios relative to other materials.
Titanium and its alloys are utilized in aero-engine and airframe manufacture because of their outstanding strength to density ratios relative to other materials.
In addition the susceptibility of titanium to work-harden during machining impair their machining ability, hence they are referred to as difficult-to-machine materials.
As for capabilities, especially fatigue resistance, titanium alloy is better than other materials.

Recently, organic-inorganic hybrid silica materials are being proposed as promising candidates for low-k materials [6-9].
Organic-inorganic hybrid silica materials are known as low-k materials with pores through steric hindrance due to rich alkyl groups, and the dielectric constant of the films also increases through low ionic polarization.
Results and discussion Figure 1 shows the FTIR spectra of as-deposited organic-inorganic hybrid silica materials.

This criterion is the generalization of Griffith’s classical model to describe the development of cracks in brittle materials.
Usually, a failure criterion is assumed to be a fixed, limiting stress condition that corresponds to ultimate failure of the material.

Introduction With the development of technology and continuous appearance of new materials, the materials of pillow on the market are increasingly rich.
The feather pillow had poor effect compared other materials.
The materials were filled in the pillowcases with 600mm length, and 350mm width, and 50mm height.
There has relatively apparent difference between the pillow materials.
