Introduction Natural materials are characterized by low cost compared to other engineering materials [1,2].
Natural materials do not have sufficient properties that distinguish them from industrial materials, so resorting to Combining them with other materials to improve their properties by adding them as fillers or reinforcing materials to form composite materials, especially with polymers [9].

Additive Manufacturing Viewed from Material Science: State of the Art & Fundamentals J.Y.
In fact, AM technology, in spite of its significant economic impact in manufacturing has not yet drawn strong interest from material science perspectives.
Furthermore, the feature size realizable is greater than 2mm and only materials that are available in wire or ribbon form can be used.
· For AM functional gradient materials, the transition zone strategy in relation with alloy compositions and process parameters

Flux Cored Wire Material Gas Shielded Arc Welding Thick Steel Plate Welded Crack Analysis Lianzhong Zhang, JieLi Wen The Donghai science and technology College of Zhejiang Ocean Universityboat , mountain ,Zhejiang, China,316000 Email:zlz.10001@163.com Keywords: cored wire material , gas shielded ,welded crack, analysis Abstract.The world shipbuilding industry since the beginning of the last century with flux cored wire material.Since the flux cored wire material use welding materials has developed into a more efficient submerged arc welding consumables and gas shielded welding welding consumables and can be more easily combined with automated welding and robot welding.So far, flux cored material applications favored.
From the above analysis, the cracks in the text The main reason is the high hydrogen content of the weld, sources of hydrogen welding materials, Flux cored wire and CO: shielding gas.
(2) Carbon structural steel (Q235B) excellent weldability, welding, The head cracks possibility of small, but large-scale structure in the thick products The weld, sometimes because of factors such as welding materials will crack. in accordance with the welding, CO: gas The superior grade in the body of the standard request to purchase CO gas in the actual site Production control products to the most effective method of References [1] LiangRunHua, Lin are.

The materials removal rate (V/VB) was selected to be objective function.
It is comprehensive parameter about materials and tools wear.
The materials removal rate, V/VB(mm3/μm, materials removal volume per a tools wear extent) was selected as the inspection object.

In addition, the LAE mechanism of difficult-to-cut materials such as stainless steels [4] and Ti alloy (Ti-6Al-4V), has been clarified by the author.
Inconel 718 is one of the most difficult-to-cut materials [5].
A similar work softening has also been identified in ductile materials such as Al, Cu, and SUS304 when the depth of last pre-cut tL is large.
The oil-based cutting fluid “AY30” is used in the broaching process and for heavy cutting of difficult-to-cut materials.

Pure submicron-sized ZrC powder was successfully synthesized in KCl by using ZrO2, Mg and carbon black as the starting raw materials.
However, the raw materials used are expensive and the product particles also suffer from heavy agglomeration.
