| Abstract: | The forging material 2Cr13 is selected to design the second compressor centrifugal impeller of a certain engine. In the working process, the blades of this rotor part flaw, which damages the engine and influences the safety of flights. Designed the smelting method, composition control, and heat treatment process of 2Cr13 stainless steel on the basis of analysis about working stress and vibration performance of the centrifugal compressor. Additionally, obtained the optimum heat treatment process system of 2Cr13 and propose solutions for removing breakdowns of 2Cr13. |
