Mechanical properties of machinable aluminum titanate

Abstract

Aluminium Titanate (AT) has micro cracks due to thermal expansion anisotropy in the sintered bodies. In the cause of micro cracks, AT has low strength, low thermal expansion and machinability. In this study, it is purpose to improve strength of AT with machinability keeping. To increase strength of AT, we added 10-40mass% mullite, middle thermal expansion, to AT. We discussed these specimens in three point bending test and drilling test.
