In total, it accounts for almost 20% of the total manufacturing output of the economy, and it is also an important source of advanced technology and skills development for the rest of the manufacturing sector.
For instance, engineering design has shifted offshore, as has various testing and quality functions.
It is not an incremental technology upgrade from where domestic production foundries are at the moment, but would require substantial investment in automated plant, equipment and in engineering skills.
This demonstrates that not only engineering innovation and policy interventions are needed, but that business and strategic innovation will be required to recapture lost market share.
The NFTN and AFSA are much closer to the reality of the automotive foundries and must continue to participate in various automotive and policy fora to promote the automotive sector.

At present, there are various submarine engineers in the sea seismic areas.

Effect of Grain Size on the Fracture Toughness of Bimodal Nanocrystalline Materials Yingguang Liu1,a*, Xiaodong Mi1,b, Songfeng Tian1,c 1School of Energy and Power Engineering, North China Electric Power University, Baoding 071003, Hebei, People’s Republic of China ayingguang266@126.com, bmixiao.dong@163.com, ctiansongfeng@163.com Keywords:Bimodal nanocrystalline materials; Cohesive zone; Fracture toughness; Grain size Abstract:To research the effect of grain size on the fracture toughness of bimodal nanocrystalline (BNC) materials which are composed of nanocrystalline (NC) matrix and coarse grains, we have developed a theoretical model to study the critical stress intensity factor KΙC (which characterizes toughness) of BNC materials by considering a typical case where crack lies at the interface of two neighboring NC grains and the crack tip intersect at the grain boundary of the coarse grain, the cohesive zone size is assumed to be equal to the grain size d of the NC matrix.
As the deficiency of low ductility and the associated loss of toughness in some materials stop their applications in engineering.
According to engineering practice and theoretical experience, people always build a composite structure to enhance the ductility of such materials [6-8].
