Fiber reinforced refractory castables for SPF toolings [PDF]
Materialwissenschaft und Werkstofftechnik, 2008 AbstractFiber reinforced refractory castable (FRRC) is an emerging material solution to manufacture SPF tools for forming titanium alloy sheets. Indeed, FRRC are able to conserve good mechanical properties up to 900 °C. Fiber reinforcement allows to improve mechanical properties and to avoid a catastrophic failure.

Sizing of Refractory Castable Gas-Burner Using Thermomechanical Simulations [PDF]
Advances in Science and Technology, 2010 Damage is a crucial characteristic of refractory castables and has to be considered to simulate correctly the behaviour of refractory structures. But, damage modelling by finite element simulations remains difficult. Indeed, the use of a continuum damage model with softening leads to strain localization phenomena.
