The major part of the brittle α-case layer can be attributed to chemical reaction between titanium and the investment mold components. To improve the ductility of the cell struts by eliminating the brittle surface, a pickling-vibration treatment was developed by which the α-case layer is chemically removed. References 1 W. Pompe, H.
