摘要
Therelationshipbetweentheplane-orientationfunctionandthespace-orientationfunctionofwhiskersinwhisker-reinforcedmetalmatrixcompositeswasanalyzedtheoretically.Theactualorientationofwhiskersintheas-cast20%SiCw/Mgcomposite(SiCwcontentinvolumefraction)wereinvestigated,andtheelasticmodulusofthecompositewasmeasuredwithanultrasonicvelocityanalyzer.Resultsshowthatthereisanevidentdifferencebe-tweentheplane-orientationfunctionandthespace-orientationfunctionofwhiskersandthespace-orientationfunctioncanrepresenttheactualconditionofthecomposite.Onlybyusingthespace-orientationfunctionofwhiskers,thedifferenceofelasticmodulusoftheas-castcompositeindifferentdirectionscanbeexplainedreasonably.
