Effect of Alloying Elements to Aluminium on the Wettability of AL/SiC System
Wetting Sessile drop method Surface tension Aluminium alloys
2009/10/13
The wettability at a liquid Al-alloy/SiC interface was evaluated by the sessile drop method at 750C. The wetting angle, , of a sessile drop on SiC substrate decreased with the addition of Pb, Mg and...

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.
Examination of the effect of slitting roller shape on band slitting during the multi slit rolling process
Numerical techniques FEM Slitting rollers
2010/2/8
Purpose: Basing on the results of computer simulations, it will be possible to choase proper technological parameters for the slitting rollers (such as shape), which will assure the slitting of the ba...
