Explosive Consolidation and Its Application on Preparing of Ultra-Fine Grained Tungsten Plasma Facing Material Shu-Ming Wang1, a, Qing-Zhi Yan1, Wei-Ping Shen1 and Chang-Chun Ge1 1School of Materials Science and Engineering, University of Science & Technology Beijing, Beijing 100083, China awangshuming03@mails.tsinghua.edu.cn Keywords: explosive consolidation; Self-Propagating Combustion; Plasma Facing Material Abstract.
Nuclear fusion is a promising source of environmental friendly energy for the future, and the ultra-fine grained Tungsten (W) is a hopeful candidate material to be used as plasma-facing materials (PFMs), which are the key materials in the International Thermonuclear Experimental Reactor (ITER), for its many useful advantages.
Plasma facing materials (PFMs) is one of the key materials in ITER which will work in extreme conditions, including complex thermal, mechanical, and chemical loads as well as strong irradiation.
Over the past few decades, many materials were tested as PFMs including both low-Z materials (Be, C, carbon fiber composite (CFC), B4C, etc.) and high-Z (W, Mo, etc.) materials [2, 3].
However, the embrittlement of Tungsten material restricts its application on plasma-facing materials (PFMs) [4, 5].

Low carbon building need low carbon building materials, low carbon decoration materials.
Decoration engineering design, low carbon construction has become an important strategy to protect environment and cope with climate change in decoration industry.
In the huge building and decoration industry system operation process adornment material production and processing, construction are cluttered with carbon emissions, if the energy consumption in decoration engineering construction and manufacture process is all to among them, carbon emissions will be more big.
Development direction and key products of Low carbon decoration materials First,develop low-toxic, non-toxic, low pollution of architectural coatings.
Eighth,develop low carbon steel tubes. since Long-term, our country residential project in engineering building, indoor drainage works iron pipes, indoor water supply works galvanization steel tube is given priority to.

(3) It only based on dimension driving, so it has great limitations in engineering applications.
So the engineering constraints such as weight, load, power, reliability and other key design parameters are establish contacts directly with the geometric equations as restrictive conditions to drive model change.
As the three-dimensional model created by SolidWorks and the generated drawings are linked, so using engineering constraints as the initial conditions also drive the update of all engineering drawings. 6.
