| Abstract: | This paper introduces the test result that the heat-plasticity of chrome alloy cast iron is increscd significantly by virtue of a few rare earths elements in it.Through the agency of the microscope, electron microprobe, ion probe and other means, the influence of rare earths elements on sulphur, silicon, carbide and other impurities which exist in chrome alloy cast iron is studied and discussed.The reason that rare earths elements increases the heat-plasticity of chrome alloy cast iron is also presented. |
