With subsequent heat-treatments balanced mechanical properties can be achieved. Examples for the fabrication of -TiAl components employing a near conventional forging route are given.

Due to high volume fractions of -phase at elevated temperatures the alloy can be hot-die forged under near conventional conditions, which means that conventional forging equipment with minor and inexpensive modifications can be used. In order to increase the deformation window a novel Nb and Mo containing -TiAl based alloy (TNM TM alloy) was developed, which solidifies via the β-phase and exhibits an adjustable β/B2-phase volume fraction. Because of the small “deformation window” hot-working of -TiAl alloys is a complex and difficult task and, therefore, isothermal forming processes are favoured.

Finally, the effect of two-step heat-treatments on the microstructure and the mechanical properties is discussed. Then, the development of a “near conventional” hot-die forging route for this type of intermetallic material is described. In the beginning the main emphasis is put on the design of a -TiAl based alloy which exhibits excellent hot-workability.

Instagram remains the most popular mobile app on the planet for posting and sharing images, but what happens to all of those great photos once they’re posted? In most cases, they slide down users’ timelines until they’re forgotten forever, but now there’s a way to put all those photo filters to use more effectively.Ĭapable Bits’ Wallgram app allows users to instantly transform their Instagram photos into terrific looking wallpapers. Wallgram for the iPhone serves a single purpose: it takes photos from Instagram and turns them into pretty terrific wallpapers. Every once in a while we catch wind of a nice addition that is offered for free for a limited time, however, and Wallgram is one such application. The quest for great iPhone apps is ongoing and it gets more difficult each day, as thousands of apps continue to flood Apple’s iOS App Store.
