The microstructure shows differences in grain structure. materials with variations of si 0 wt% and materials with variations of si 0 wt%, 1 wt%, 2 wt% and 4 wt% have different grain sizes.
Weaknesses in steel materials at corrosion resistance.
Almost all steel materials are used in the ship's hull [1-3].
The following is Table 1—composition of materials.
These materials are cut and weighed according to the mixing weight ratio.

Experimental study on the possibilities to decrease the coefficient of restitution after impact TODOR Nikolov Penchev1a, IVAN Lyubomirov Altaparmakov2b, DIMITAR Nedelchev Karastojanov3c 1Tehnical University, Materials Processing Department, 8 Kliment Ohridski Str., 1797 Sofia, Bulgaria 2 Tehnical University, Department of Applied Mathematics, 8 Kliment Ohridski Str., 1797 Sofia, Bulgaria 3 Bulgarian Academy of Science, Institute of Computing and Telecomunications, 2 acad.Angel Bonchev, Sofia, Bulgaria atpenchev@tu-sofia.bg, bialt@tu-sofia.bg, cdimikara@abv.bg Keywords: impact, coefficient of restitution, forging, die forging, pile driving Abstract.Technological processes such as forging, die forging, pile driving, etc., are realized as a result of a collision between two bodies.
Introduction The coefficient of restitution after a collision e was introduced by Newton as a result of experiments on the collision between spherical balls of various materials conducted by him [1].
Further studies are needed to explore the possibility of reducing the rebound in the technological impact processes such as forging, die forging, pile driving and high velocity briquetting of waste and powder materials.

Preface On the successful basis of GBMCE 2011, 2012 the Second International Conference on Green Building, Materials and Civil Engineering (GBMCE) will be held in SanYa during August 22-23, 2011, The conference aims mainly at promoting the development of Green Building, Materials and Civil Engineering, strengthening the international academic cooperation and communications, and exchanging research ideas.
I think GBMCE 2012 will be the most comprehensive Conference focused on the Building, Materials and Civil Engineering.
We believe the proceeedings will provide the readers a broad overview of the latest advances in the field of Building, Materials and Civil Engineering.
On behalf of the guest editors for this conference proceeding, We would like to thank the National 863 Program of China, National Science Fund of China.
Thomas Wohlbier, Managing Editor of Journal of Advanced Materials Research, is greatly acknowledged.

Numerous studies showed that if the construction was introduced to new materials and equipment, the conflicts between relevant professional subsystem and product material would take place and it would give the project a negative impact and the risks of technology and market.
The employer shall bear the risk of selection and providing for the materials and equipment; materials, the designer shall bear the risk of equipment function. (4) Capital risk allocation.
