The Influence of High Energy Ball Milling on the

Investigations of high energy milling parameter of aluminum or siluminum based materials with ceramic particles has been conducted. Work consists of two parts. In the first part two types of composite powders with the same metal-ceramic ratio were synthesized via planetary ball milling with the same milling parameters. After SEM studies it has been shown, that despite of materials similarities

Phase development during high-energy ball

High-energy ball-milling of powder mixtures of zincite (ZnO) and iron (α-Fe) at different weight ratios was performed in air using a planetary ball mill with a stainless steel milling assembly. Structural and microstructural changes during the ball-milling (up to 30 h) were monitored using X-ray powder diffr
