Ti doesn't change phase until 883°C, we take our de-bonds up slowly ~25°/min. to 400°C and a 4 min hold. Cement is reduced to ash basically in this cycle. This especially true with emax which has much less tensile force strength than Zir so Slow heat rise. The cement is doing its thing burning out, thermal expansions of different materials, what could go wrong400c is about the average for debonding, it makes cement goopy/soft/whatever you want to call it without impregnating the glaze, also I am not sure at what temp the Ti abutment begins to get funky.
