The mechanical properties of the quenching material and partitioning material, and stability of the retained austenite phase, were examined.

Another common dissimilar metal combina-tion involves the use of high-nickel alloys for weld repair of cast iron. Fe-55Ni welding elec-trodes are used to make weld deposits that can hold in solid solution many of the alloying ele-ments common to cast iron. Furthermore, weld

However, non-magnetic castings are required in some applications and to meet this need the compositional balance is altered to produce 100% austenite.
