    Effect of the cooling rate on the mottled cast iron microstructure designed for the mill rolls
    (2009) Krawczyk, Janusz Ryszard; Pacyna, Jerzy
    The influence of the cooling rate changes on the mottled cast iron microstructure was described in the paper. The investigated material constituted mottled cast iron, spheroidal, chromium-nickel. This cast iron, according to currently binding standards was marked GJS-HV300(SiCrNi2-3). The microstructure was described both qualitatively and quantitatively. The discussion of the formation mechanisms and their influence on the morphology of structural components and phases was conducted. The heat treatment was performed in such a way as to obtain either a pearlitic or a bainitic matrix as well as a different morphology of lederburitic cementite and graphite precipitates for the same matrix.
