Abstract:

A technique has been developed for preparing thin foils of Ti-X specimens containing alpha, beta and intermetallic compound based upon ion milling performed in a cold stage without any intermediate electrothinning. Application of this technique to a Ti-6 WO Cr alloy reacted at 625 C yielded the following orientation relationships among the three phases. This result is in accord with a prediction of our theory of precipitation at interphase boundaries. A selected area electron channeling pattern study has been made of orientation relationships developed during the massive transformation in a Ag-26 AO Al alloy.
