An exemplary shield includes an attachment mechanism disposed on an outer surface to attach the shield to a joint of a boreless compressor wheel and a passage extending from a proximate end of the shield to a distal end of the shield. An exemplary method includes inserting a shield at least partially in a joint of a boreless compressor wheel and treating, at least partially, an end surface of the joint to thereby reduce fatigue of the boreless compressor wheel. Other exemplary joints, compressor wheels, shields, etc., are also disclosed.
