Abstract:

HOT ISOSTATIC PRESSING OF SILICON NITRIDE AND SILICON CARBIDE IN NITROGEN PRODUCES STRUCTURAL CERAMICS WITH STRENGTH MORE THAN 20% ABOVE NORMAL HOT PRESSED STRUCTURES. THE MECHANISM OF STRENGTHENING BY THIS METHOD IS NOT UNDERSTOOD. EXAMINATION OF THE STRUCTURE OF THE BODIES INDICATE THE PRESENCE OF ACICULAR SIC OR SI3N4. IF THIS IS FORMED "IN SITU", IT SHOULD BE POSSIBLE TO ENCOURAGE THE FORMATION OF FIBERS, PRODUCING A CERAMIC FIBER REINFORCED CERAMIC WITH GREAT TOUGHNESS. THIS STUDY WILL DETERMINE THEMECHANISM OF STRENGTHENING BY HOT ISOSTATIC PRESSING IN NITROGEN AND WILL GIVE A PROCESS FOR HIGH STRENGTH CERAMICS.THE CONTRACTOR SHALL INVESTIGATE THE HOT ISOSTATIC PRESSING OF SILICON NITRIDE AND SILICON CARBIDE IN NITROGEN IN ORDER TO DEFINE OPERATING CONDITIONS, RAW MATERIAL PROPERTIES AND THE ROLE OF CERTAIN ADDITIVES REQUIRED TO PRODUCE BODIES WITH SUPERIOR STRENGTH AND TOUGHNESS.
