The shell rupture for shock initiating of a bulkhead igniter occurred in low temperature test. Simulation analysis, technology review, chemical composition analysis, mechanical property testing, metallographic examination are performed during the failure analysis. The results show that the heat treatment process of vacuum furnace caused the higher hardness, thicker microstructure grain, and lower impact toughness of the shell. Thus overload rupture occurred under explosive shock at low temperature.
Key words： overload rupture; heat treatment; impact toughness; failure analysis
