George,
 The steel needs to be supported from the outside or captured on the

edge. The explosive cladding Paul was looking into would be the best. The
problem is checking warpage without running the engine, which could destroy
the rotor the housing or both. The plate could be a high strength steel  and
then wouldn't expand as much.
