Research status of ductile iron nuclear spent fuel container in China

In 1991, Gong Jinying of Qiqihar Institute of light industry studied the relationship between the micro fracture morphology and mechanical properties of large section ductile iron container with different wall thickness. Fourteen tensile fracture specimens were selected from five different isothermal surfaces on the fan-shaped block for SEM observation....
