... by the heat treatment of a white iron casting in a neutral atmosphere ( Ref 1 ). Decarburization is limited and produces a shallow decarburized surface layer and a thin associated pearlitic transition zone. The rest of the casting has an ordinary malleable cast iron microstructure. Sometimes the term...
