MANUFACTURE OF ALUMINUM SERIES METAL MATRIX COMPOSITE AND ITS MANUFACTURE

摘要

PURPOSE:To satisfactorily show a reinforcing effect by whiskers ion a composite by forcing a molten metal into a preform obtd. by coating aluminum borate whiskers with spinel. CONSTITUTION:Al borate whiskers shown by 9Al2O3.2B2O3 or 2Al2O3.B2O3 are coated with spinel. The molten metal of Al (alloy) is poured on the preform of these whiskers and are infiltrated into the voids of this preform. Thus, the composite in which a reinforcing effect by the whiskers are satisfactorily shown can be obtd.
