CORROSION RESEARCH ROUND‐UP Available to Purchase

Titanium research and development. The mechanical and physical properties of titanium alloys now in production or in an advanced stage of development are reviewed, with particular reference to their fatigue and notch‐fatigue characteristics. Creep characteristics at high temperatures, and the effect of heat‐treatment on this property are also discussed and a brief description is given of current investigations on hydrogen in titanium, properties of titanium tubing under pulsating pressure tests, and the production of extruded sections.—(N. P. Inglis, Metal Ind., London, 1957, 90, 185–188, 194, 205–206.)
