Solid graphitization annealing process of cast iron

The solid-state graphitization process of cast iron is essentially a process of transformation from metastable cementite to stable graphite. Graphitization annealing process is shown in Figure 1. In the process of slow heating of gray cast iron, cementite gradually decomposes, and carbon atoms precipitate from cementite and form nuclei...

Inoculated cast iron

High quality and high strength gray cast iron should have fine and uniform A-type graphite and fine flake pearlite matrix structure. This kind of structure usually needs to appear in relatively low carbon equivalent cast iron, but this kind of cast iron liquid iron General eutectic undercooling is large,...

Chemical composition of high chromium cast iron

In order to better analyze and study the types of secondary carbides obtained after quenching of high chromium cast iron, the chemical composition of carbides of high chromium cast iron was analyzed by EPMA point scan, and the diffraction pattern of high chromium cast iron was calibrated by saed....
