Metallurgical Characterization of Waspaloy Presenting Variations on Chemical Composition, Grain Size, and Hardness

Waspaloy is a super alloy used to manufacture some aeronautical parts subjected to high temperatures and stresses, during it thermo-mechanical processing cracks are generated, causing that some parts will be rejected during their processing. In order to determine the causes of these cracks, this all...

Description
Summary:Waspaloy is a super alloy used to manufacture some aeronautical parts subjected to high temperatures and stresses, during it thermo-mechanical processing cracks are generated, causing that some parts will be rejected during their processing. In order to determine the causes of these cracks, this alloy was characterized using techniques such as Chemical Analysis, Optical Microscopy, Scanning Electron Microscopy, and EDX analysis. Heterogeneous grain size on the microstructure causes a non-uniform strain distribution on these parts, and may originae cracks on zones with different grain sizes.
