Abstract: |
Mechanical
alloying (MA) is used to produce new materials which
cannot be obtained by other production processes. Simplified two powders A und B are mechanically joined to a
new powder C which has new material properties. A particle based
mathematical model for MA is developed for improving the mechanistic
understanding of MA in a high energy ball mill. The
model focuses on treatments from special milling devices and an investigation
of breakage and fusion for ceramic materials. It was implemented by using
parallel Monte Carlo methods for a large number of individual particles. To
compare the simulation results with experimental data the system SiC and Al2O3 was investigated. The aim of this paper is to
improve the mechanistic understanding of MA in a high
energy ball mill. Particularly the phenomena observed by milling of
ceramic powders are investigated. |
