Synthesis and grain growth kinetics of in-situ FeAl matrix nanocomposites (Ⅱ): Structural evolution and grain growth kinetics of mechanically alloyed Fe-Al-Ti-B composite powder during heat...; Abstract: Morphological changes, structural evolutions and grain growth kinetics of mechanically alloyed(MAed) Fe50Al50, Fe42.5Al42.5Ti5B10......
the problem that particles tend to be agglomeration and poor crystallization. The existing theory of crystal growth, such as the screw dislocation growth theory put forward by FRANK [15] and VLS growth theory [16], can well illuminate the growth of crystal under the heterogeneous system without template. The growth direction of this kind of crystal with screw shape is perpendicular to screw......

of the Ni-based super alloys are not isotropic [4]. For instance, blades with [001] crystal index have higher temperature creep strength compared to those with [011] or [111] index. During the growth of grains, the preferred growth direction is known to be [001]. The goal of single crystal casting is to align the [001] single crystals along the length of the turbine blade. However......
