Following the work done at NASA to use carbon fiber reinforced carbon (CFC) materials as a replacement for mainly cast steel for Fixtures, Racks or parts of it in heat treatment industry, a successful development of a new generation of ingenious Fixtures was started in the mid 1990s by the author and his team. CFC have been shown to have lower density, lower thermal expansion and increased strength at high temperatures resulting in smaller, lighter Fixtures with shorter heating and cooling times, better process capability and, in some cases integrated material flow. The thermochemical and other details for still three main challenges like 1st oxidation of CFC, 2nd possible interaction between CFC and the steel parts and 3rd CFC Fixture interaction with liquid media like oil will be discussed. Furthermore, successful industry CFC Fixture applications which pay-off on several reasons are introduced.
