Failure Experience with and Failure Anticipation in Titanium Components
The initial use of many technological developments and/or the utilization of new materials, particularly when they are used in highly loaded structures, often incurs some risk of serious failures. In fields such as atomic energy, advanced transportation systems or mass produced housing one must optimize between the high reliability of over-conservative but less efficient design, and the lower reliability of a highly efficient but less conservative design. The confidence necessary to avoid over-conservative design comes from adequate quality assurance and the ability to predict the actual in-service behavior of the material. The former offers many opportunities for further progress, particularly in the nondestructive inspection of titanium; the latter is the subject of this paper. In particular, we are concerned with several aspects of the problem of predicting in-service behavior of titanium from materials and component testing.
