Characterization of Cooling Rate and Microstructure of Rapidly Solidified Spherical Mono-Sized Sn-1.0Ag-0.5Cu Particles Ying-Yan Hu1,2*, Jun-Feng Wang2, Can Li2,4, Jian-Qiang Li2,3* 1School of Engineering and Technology, China University of Geosciences, Beijing 100083, China 2National Engineering Laboratory for Hydrometallurgical Cleaner Production Technology, Key Laboratory of Green Process and Engineering, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China 3School of Chemistry and Chemical Engineering, University of Chinese Academy of Sciences, Beijing 100049, China 4School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China *Corresponding author: Ying-yan Hu, Email yyhu@ipe.ac.cn; Jian-qiang Li, Email jqli@ipe.ac.cn.
The material properties are depended on the microstructure which is directly related to the cooling rate of the material.
In order to enable metallic materials with excellent properties, it is necessary to understand the microstructure evolution upon solidification process and the relationship with cooling rate.
Experimental Pure Sn(99.9 wt.%), Ag(99.9 wt.%), Cu (99.9 wt.%) supplied by Beijing Li Cheng Chuang Xin Metal Material Technology Co., Ltd., Beijing, China, were used to prepare Sn-1.0Ag-0.5Cu alloy.
Graphite can be acted as the crucible materials for the Sn-1.0Ag-0.5Cu particles prepared by POEM experiment.

Maintaining biodiversity is a key issue and this requires compatible water qualities, characterized by several parameters: fish, aquatic plants, phytoplankton, zooplankton, benthic animals, birds, etc. [13].
To optimize system performance and minimize energy loss, various pipe diameters, flow rates and pipe materials were examined.
In addition to water replenishment, the highest possible energy recovery (cycle efficiency) and water quality compliance (application of a solution close to nature) were highlighted as key aspects during the optimization.
Calculating the head losses and friction factors in inter-basin pipe network The materials and the wall-roughness of the two pipes are different, which results in different friction, as shown in Fig. 6.

For example, the pulverized coal suspension combustion technology is the key technology for modern large coal-fired utility boilers.
Although a large number of non-homogeneous fluid measurement technology has been studied by technical personnel at home and abroad, but a good solution has not been received either in theory or engineering applications.
Through the application of relevant principles, advanced technology, materials and design concepts, a new type of gas-solid two-phase flow average velocity measurement system was developed.
By considering the flow resistance, material properties, manufacturing difficulties and other factors, the optimum cross-sectional shapes of a single probe tube was identified as the circular.
The main pipeline in the system is constituted by a seamless steel pipe, its size is φ245×6.5mm, material is Q235.
