A brief review is presented of techniques for special testing of materials, test results and sources of information on special testing procedures. Test data on tensile properties are presented for sheet Al and Ti alloys and for AISI 31O stainless steel to -423F. A paper on the compression testing of sheet at elevated temperatures with compression testing jigs and associated techniques is discussed briefly as well as a report on burst tests on deep-drawn pressure vessels.

Research activity on Ti-13V-11Cr-3Al, Ti-8Al1Mo-1V, and Ti-8Al-10V alloys for both high and low temperature applications is reviewed. Mechanical properties, heat treatments and processing techniques are briefly discussed. Sources of information on new developments are indicated.
