| Abstract: | In this paper,the authors try to investigate the possible relation between the fracture toughness Kc and the temperature T for nodular cast iron,who are ues the results from Rauh,Bullough and the domestic studies in the rules of the stress-driven migration of point defects to a crack,the following results are observed through the test.The fracture toughness of nodular cast iron decrease as temperature increase.The results seem in good as compared with the calculated fracture toughness and the tested fracture toughness. |
