Introduction of Intelligent Materials Intelligent material is the fourth generation materials after the natural materials, polymer materials and artificial materials, it is one of the important development directions of the modern high-tech materials.Concept of intelligent materials was proposed first by Japan scientist in 1989.
Intelligent materials can be divided into optical fiber, shape memory alloys, piezoelectronic materials, magnetostrictive materials and electrostrictive materials etc. according to their different functions.
Relationship between polymer deformation and temperature Conclusion Development and widely application of intelligent materials will result in a major revolution in materials science.

With the continuous development of Chinese science and technology, structured ultra-light porous metal materials are a new type of multifunctional materials that have emerged with the increasing demand for diverse materials preparation and machining technologies in recent years.
Porous metal materials are materials that are good for the environment.
In addition, with the rapid development of science and technology, we have more scientific and technological means, and thus have greater ability to develop and research new materials.

The metal materials play important roles in the area of the industry.
As we all known, the structure of the materials’ organization affect the using properties directly.
In the condition of active service, most materials losing efficacy begin on the surface.
Comparing with the common materials with coarse grain, the nano materials are with super high strength, super high hardness, good ductility and other excellent properites.

In order to understand the effect of these materials, test LED samples were prepared with different sets of packaging materials.
As a very important part of LED compositions, packaging materials are sensitive to high temperature.
Thus, the failure of packaging materials is one of the most important reasons of lifetime reduction of the whole LED models.
In order to discover the failure behavior and principle of packaging materials, some typical samples which were the LED modules with common packaging materials including phosphor and silicone were used to undertake high temperature aging test.
By the means of measuring the luminance of samples online, the failure process of packaging materials had been revealed.

Experimental The main raw materials are consisted of magnesium slags, kaolin and alumina.
To exclude the adsorbed moisture, the materials were taken into constant temperature hot-blast oven of DH-101 and dried at 90℃for 12h.
