Thermal shock and thermal cycling experiments on silicon nitride were performed, whereby the maximum temperatures were low enough that the material remained in the elastic region. Life-time predictions have been derived from the experimental results by means of a theoretical model. First investigations were also done on fracture processes caused by high temperature creep.enAusfallwahrscheinlichkeitceramicshigh-temperature creepHochtemperaturkriechenKeramikprobability of failuresubcritical crack growththermal cyclingthermal shockThermoschockThermowechselbelastungunterkritisches Rißwachstum667621671conference paper
