Determining Austenite Grain Size of Steels: 4 Methods Metallurgy

WebGrain size has a measurable effect on most mechanical properties. For exam-ple, at room temperature, hardness, yield strength, tensile strength, fatigue strength and impact strength all increase with decreasing grain size. Machinability is also affected; rough machining favors coarse grain size while finish machining favors fine grain size. WebThe AISI 422 martensitic stainless steel, as one of the high strength alloys, is widely used for rotors and bolting of gas turbine blades due to its good balance of high strength and ductility [1]. To obtain optimal properties, close control of the grain size is crucial. The austenite grain coarsening occurs easily during Grain size is a key measure that defines the characteristics of metals and alloys. However, this factor rarely gets the attention it warrants.
