Abstract��Be aimed at the crack on the high strength and enlarged bolts.the macro fracto graphy and micro fractography were observed and analysed primarily. By thoughfully analyzing��the results showed that the primary failure mode on bolt was the H2��induced brittleness originated from metallurgical process.
