Abstract: Indentation is a mature technique that has been widely used in materials science to investigate the mechanical properties of metals and thin films.
The indentation technique provides accurate modulus and hardness values of materials over many length scales and can target specific microstructures within heterogeneous materials.
The breaking force and toughness results determined are based on the materials overall structure and composition.

For both materials the strength decreases with storage time.
At pH 7 both materials were stable for the test period.

The Analysis for Low Carbon Materials on Planning and Development Determinants Chenggang Xu1,a,Hui Cheng1,b 1College of Economics & Management, Three Gorges University, Yichang, Hubei, 443002, China ammm98@126.com, bnnn98@sina.com Keywords: Low carbon industry, Environmental friendly materials, High-carbon materials, Public choice.
Because OY1 is current the production on the environmental friendly materials.
So reduction yield Y1C1 on environmental friendly materials actually is that H's government transfers this part of resources to produce high-carbon materials .So Y1C1 can be understood as the current production or consumption on high -carbon materials.
But in the long run, as long as the time is long enough, the high-carbon materials can be replaced by environmental friendly materials.

MgAl2O4 spinel b) a) Fig. 2 Composite materials based on EN AC-44200 Al alloy, (a) ultimate tensile strength of unreinforced aluminum alloy (0%) and of composite materials reinforced with 10 and 20 vol.% of Saffil fibers at 20-300oC, (b) Fracture of composite materials with cracked fibers partly covered by MgAl2O4 spinels –scale bar 5 mm Normally composite materials applied in the production of car engine parts are subjected to several thermal cycles.
Thus, coefficients for composite materials at higher temperatures of 300-400 oC were significantly smaller and decreases from 22 to 13x1/106 deg correspondingly for unreinforced Al alloy and composite materials with 20% of fibers.
