Abstract: The orientation relationship between TiC and Ti₂CS in a Ti-containing weathering-resistance steel were observed by TEM technology and X-ray energy dispersive spectrum (EDS). The results showed that many tiny TiC (titanium carbide) were forming on Ti₂CS (titanium carbide sulfide), which precipitates on relatively higher temperature than TiC, The orientation relationship between TiC and Ti₂CS is ; . The epitaxial growth is important mechanisms for titanium carbide forming in steels.

Abstract: It is shown using aluminum single crystals with kink bands like a plate through the depth that the nucleation and growth of recrystallized grains (RGs) on/in the surface precede those in the interior.

Abstract: The motion of <111> tilt and mixed tilt-twist grain boundaries with misorientation angles in the range between 34° and 42° in pure Al bicrystals was measured over the temperature range between 310 and 610°C. The experiments revealed that the change of the set of boundary planes in the curved moving tilt boundary does not affect its motion. The shape of the curved moving part of the mixed tilt-twist boundary was measured and compared with analytically calculated boundary shape. The results have shown that an increase of the twist component along the curved mixed boundary in studied geometrical configuration does not affect its steady-state motion. Similar to the behaviour of <111> pure tilt boundaries, the mobility of <111> mixed tilt-twist grain boundaries in the vicinity of special misorientation å7 depends on the misorientation angle in a non-monotonic fashion.
