  • Developments in investment casting process—A

    2012-11-1 · It is difficult to machine the three dimensional complex shape of the blades. Therefore, it is necessary for the researchers to improve the accuracy and surface finish of turbine blades. Mitchell (1999) made a successful attempt in this regard to explain and improve the construction of a turbine blade. As per his study, in a turbine blade, non-uniform thickness of airfoil, thick root, curvature, and …
