    THE FRACTURE ANALYSIS OF THE HIGH STRENGTH STUD BOLT BY SEM

    • Based on the microanalyse, the fracture of the high strength stud bolt was analyzed by scanning electron microscope ( SEM ). It was observed that the tramp elements in the fire-proof material particles have separated out to the crystal boundary so that lead to local brittle crystal boundary, therefore the stud bolt was broken under small stress conditions.
