I own a couple of steel frames which are going strong into their second century. My most used bike is an aluminium Principia which i bought in 1996 and which has seen around 100k km; my buddies Klein Quantum II from 1994 probably has twice as much on the meter. All of these are still going strong. My 1998 Moots looks like new apart from cracked decals and some cospetic spots where the cables rubbed it gently.
I have seen quite a few CFK frames that showed several signs of fatigue, though. Usually the glued-in or molded-in parts like the BB casing or the headtube steerer mounts become creaky or even loose.
So i'd say if it is a well engineered and well made metal frame, unlimited lifespan. Ti has the advantage of the "immune to anything" finish. CFK - not so sure.
