The influence of carbon addition on the aging response of quenched Ti-13wt. % Cr has been investigated using hardness tests, tensile tests, optical microscopy, scanning electron microscopy, and transmission electron microscopy. The addition of carbon improves the homogeneity of α precipitation,...
Deformation behavior at room temperature was examined in near-β titanium alloys, Ti-10V-2Fe-3Al, containing small amounts of N up to 0.2 mass%. After a β solution treatment, thermally induced α″ martensite is formed in the N-free alloy but no martensite is formed in the 0.1 and 0.2% N alloys. In...
Beta alloys are potentially useful for several types of nonaerospace military applications. The potential applications to be discussed in this article include armor, body armor, mortar barrels, and missile launch canisters.
TIMETAL LCB was introduced more than 10 years ago targeting automotive suspension spring applications. The alloy development aim was to use a low-cost formulation by selecting less expensive raw materials than typical beta titanium alloys. Following the first successful application ofTIMETAL LCB...
Beta titanium alloys are increasingly the best choice for automotive and aerospace applications due to their high performance-to-density ratio. Among these alloys, the TIMETAL Ti-LCB is already used in the automotive industry because it presents excellent mechanical properties and a lower cost...
A comparison is made between the creep behavior of the Ti-35V-15Cr and Ti-35V-15Cr-0.2C alloys at 500 to 580 °C within the stress range of 200 to 300 MPa. The creep resistance of Ti-35V-15Cr-0.2C is considerably improved by the incorporation of Ti2C particulates into the Ti-35V-15Cr-0.2C matrix.
Beta titanium alloys provide useful combinations of physical and mechanical properties, as well as a wide range of processing options and generally good corrosion properties. Throughout the past several decades, many β alloys have been researched, yet only a handful of these currently enjoy...
Beta titanium alloys have been available since the 1950s (Ti-13V-11Cr-3Mo or B120VCA), but significant applications of these alloys, beyond the SR-71 Blackbird, have been slow in coming. The next significant usage of a β alloy did not occur until the mid-1980s on the B-1B bomber. This aircraft...
TIMETAL 555 is a high-strength near-β titanium alloy that was designed for improved producibility and excellent mechanical property combinations, including deep hardenability. The nominal chemical composition of TIMETAL 555 is Ti-5wt.%Al-5wt.%Mo-5wt.%V-3wt.%Cr. This article provides a summary of...
