cast iron crystallization pinholes compacted graphite
2009/10/23
The contribution is aimed at study of influence of chemical composition of compacted graphite cast iron (CGI) on microstructure and surface quality of castings, particularly on the occurrence of pinho...
Study on the Microstructure and Texture of 3003 Aluminum Sheets Rolled by Laser-Textured Roll
Aluminum Laser-Textured Roll
2009/9/2
In order to improve the surface quality and formability of 3003 aluminum alloy sheet, laser-textured rolls are used in cold rolling. The influences of the cold rolling procedures with conventional and...
