Was Eva Braun's body ever found in Hitler's bunker or in the court yard of the Chancellory?

Germans in the bunker who survived the war insist that, after Hitler shot himself, his and Braun's body were moved outside and cremated by the Germans. However, cremation is not as easy as one might think and takes a long time to do it right. It is probable that portions of the bodies were unconsumed, and that the Russians did recover some of them.
