Selected characteristic of silumins with additives of Ni, Cu, Cr, Mo, W and V
Journal Title: Archiwum Odlewnictwa - Year 2010, Vol 10, Issue 2
Abstract
The study, presents an investigation results of new grades of silumins containing of: 7,0÷17,0% Si, 4,0% Ni, 4,0% Cu and 0,5% Cr, Mo, W each as well as V. The influence tests were carried out of - antimony addition, strontium and phosphorus modification, supersaturation and ageing processes - on microstructure and silumins hardness. Revealed that investigated silumins, depending on the state, are characterized by hardness in the range of 80÷180 HB.
