| Abstract: | According to the theory of strengthening ADI austenitic-bainitic ductile iron)the thesisdiscusses the structure, design and the range of temperature for austenitizing. The experi-ment shows that the matrix structure should be designed as acicular bainite and a part of re-maining austenite in order to gain the vermicular graphite cast iron with optimum strengthand toughness,and the structure should encircle the graphite. |
