Polysynthetic twinned TiAl single crystals for high-temperature applications
TL;DR: It is reported that Ti-45Al-8Nb single crystals with controlled lamellar orientations can be fabricated by directional solidification without the use of complex seeding methods, and could provide expanded opportunities for higher-temperature applications, such as in aeronautics and aerospace.

Effects of B, C, and Zr on the structure and properties of a P/M nickel base superalloy
TL;DR: In this article, the boron and carbon levels of a P/M nickel base superalloy were systematically varied in order to determine the mechanisms by which these elements strengthen the alloy, and their optimum concentration.
