Through the chemical composition analysis, metallographical observation, Manson-Haferd parameter extrapolation and thermal-stress calculation, it is found that the failure of conic nozzle was caused mainly by the thermal stress.
通过对一失效的下集气锥形管的金相宏微观检查、Manson Haferd参数估算锥形接管的持久寿命以及热应力的计算 ,发现锥形接管的失效原因主要是由温差应力所导致。
