Research overview:
As a case study of advancing functionality of cast iron system, study on improvement of corrosion resistance of nodular graphite cast iron used for the material for the bolt laid underground. This year, samples added with combined tin and copper, molybdenum and indium is prepared and survey・investigation on corrosion resistance is performed. On steel alloy system, development of the material provided with both high strength and ductility is being performed by composition control technique combining processing and heat treatment.
