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...
The microstructure of HS 6-5-2 steel in the areas overlapping remelting obtained by the use of GTAW method
Heat treatment Metallography GTAW method Directional crystallizatio
2011/3/15
The work presents microstructures of HS 6-5-2 high-speed steel from the areas overlapping remelting. The surface layer of the steel was remelted using the GTAW method. The microstructure photos were t...
Effect of the microstructure on tribological phenomena occurring on the surface of a mill roll made of SA5T cast iron (GJSL-HV600 - GJSL-330NiMoCr12-8-3)
Metallography Wear resistant alloys Mill rolls Mottled cast iron
2011/3/15
This paper deals with the role of the microstructure in the tribological wear processes occurring in a cast iron mill roll. For this purpose, a piece of a broken roll, made in Italy, was collected.
Microstructure of Remelted Zone of HS 6-5-2 High Speed Steel
Heat treatment – metallography Directional crystallization Volumetric crystallization
2011/3/11
The work presents microstructures of the remelted zone of HS 6-5-2 high-speed steel. Zones of this kind can be created as a result of treating the material with a CO2 laser beam. The laser processing ...
