Few manufacturing processes are perfect and errors, minor changes in a processing cycle, etc., can lead to defective regions in a product which may influence service performance. Over the past decades the demands of high technology areas such as these in the aerospace industry have required that such defects be eliminated from components and the advances in quality control, NDI, etc., habe probed in general very successful in improving product integrity. Titanium alloys have formed part of such programs and the service record of these materials has been excellent. However, occasional problems have been encountered especially when the defects occur on a small scale and are difficult to detect by NSI techniques. Description of the types of defects that have been encountered were identified in the first semi-annual report. This has been used to establish an experimental and analytical program designed to gain insight into the nature and effect of two specific defects on subsequent mechanical properties.
