Fly ash as the reinforcement of light alloy metal matrix composites. Part 2: High temperature investigations

The second part of the publication presents the results of high temperature investigations of selected sorts of fly ash serving as a reinforcement in ALFA composites. Using graphs illustrating changes of sample dimensions in function of temperature, the characteristic points corresponding to the temperature of sintering, softening, melting and flowing were determined. The validity of the thermal test results was confirmed in the second series of comparative tests, performed at different heating rates. As a result of the studies, ash grades characterized by high thermal resistance were selected.
