FATIGUE IN CUSTOM 465 STAINLESS STEEL FOR AERONAUTIC APPLICATION
MetadataShow full item record
This project was originated from the national aircraft industry requirements to reduce the use of coated materials with electroplated chromium or cadmium that produce waste, which is harmful to health or the environment. The selected material is a Custom 465 stainless steel used in the aeronautical field due to its high mechanical strength. Considering the load sustained by the wheel axis of the landing gear, the Custom 465 was tested in axial fatigue. The objective is to compare the behavior of the Custom 465 stainless steel with plated AISI 4340 steel coated with cadmium. Fractographic analysis was conducted using scanning electron microscopy. X-ray diffraction method was used to determine the residual stress field induced by shot peening.
