Effect of Sample Size on Microstructure and Mechanical Properties of OFHC Copper Processed by Equal Channel Angular Pressing Fan Liua, Jingtao Wangb, Zening Mao, Chengping Zhou and Yao Jiang School of Materials Science and Engineering, Nanjing University of Science and Technology, Nanjing 210094, China aliufan_njust@126.com, bjtwang@mail.njust.edu.cn Keywords: Equal channel angular pressing (ECAP), Copper, Ultrafine grain, EBSD, Mechanical properties.
Experimental Materials and Procedures.
All of these characteristics are typical of materials subjected to SPD.
Because the simple shear deformation only exists in ideal ECAP in which materials flow through a critical boundary - shear plane.
In order to guarantee the pressure bar of ECAP stable, pressing speed is usually limited in 20 mm/s especially in hard to deform materials.

Defection Analysis Engineering designers model the bridge and analysis internal force using the software of the structure calculation according to study the defection situation of Huang-Jiayan bridge.
Against to the defection, Engineering designers proposed to strengthen Huang-Jiayan bridge using synthetic technologies of reinforcing tie-beam with steel plate yoke to reinforce the bridge mainly and other conventional technologies of bridge deck load reduction, reinforced concrete box-closed and reinforcement concrete yoke to strengthen the skewback, carbon fiber sheet to strengthen cross-section arch tensile capacity, glass fiber sheet to close the belly bar and scissors-type bar, and so on subsidiarily.
The key parts are abdominal component at the arch foot and nodes of the arch rib.
There are no new added cracks ,the old cracks are not further expansion in and some of the old cracks at the side arch ribs have the closed signs according to the following-up observation of the engineers lately.
