Abstract:

Twenty samples from small aircraft engine exhaust systems were investigated metallurgically to determine the differences, if any, between failures produced in a ground test program and failures from operating aircraft. The work included samples fabricated from a new material nickel-iron-chromium alloy recommended as an improvement for applications such as exhaust systems. The purpose also requested further information regarding the metallurgical cause of failure of conventional stainless steel exhaust system components. Author
