Ordering and mechanical strength in L1[sub 2] cubic titanium trialuminides
- Univ. of Neuchatel (Switzerland). Inst. of Structural Metallurgy
There have been many studies of the structure and mechanical properties of titanium trialuminides over the last few years, in particular those alloys modified to the L1[sub 2] cubic structure by substitution of 6 to 10 pct of the aluminum by a suitable transition metal. Such alloys are of interest as high-temperature materials in view of their reasonable strength and good oxidation resistance. Unfortunately, these alloys show low tensile ductility and toughness. Attempts are being made to improve these properties. The present report examines earlier studies determining the state of order of these intermetallics and subsequently attempts to relate the ordered state and other microstructural characteristics, such as the appearance of second-phase precipitates, to strength or ductility.
