Journal ArticleDOI
Effect of lamellar spacing on microstructural instability and creep behavior of a lamellar TiAl alloy
TL;DR: In this paper, the authors showed that the unstable nature of the fine plate contributes largely to the degradation of the lamellar structure and a rapid increase in the tertiary creep rate.
Journal ArticleDOI
Strengthening of a fully lamellar TiAl + W alloy by dynamic precipitation of β phase during long-term creep
TL;DR: In a fully lamellar Ti−48Al+W alloy, β phase precipitated by aging has been shown to reduce the primary creep rate significantly in this article, but only in the case of the unaged condition.
Journal ArticleDOI
Compositional regions of single phases at 1800 °C in Mo-rich Mo–Si–B ternary system
TL;DR: In this article, the compositional ranges of the determined Mo solid solution, silicide and boride phases were in good agreement with those of Mo-Si and Mo-B binary phase diagrams.
Journal ArticleDOI
Effects of discontinuour coarsening of lamellae on creep strength of fully lamellar TiAl alloys
TL;DR: In this paper, the effects of lamellar spacing on creep strength were examined in a binary Ti-42mol%Al alloy with fully-lamellar structure, and the authors found that the strengthening by fine lamellae becomes effective even at low stresses.
