چکیده انگلیسی
In this work, the microstructure of V-5Cr-5Ti alloy after hot forging was analyzed by X-ray diffraction, optical microscopy, scanning electron microscopy, and transmission electron microscopy. After hot forging, the microstructure of V-5Cr-5Ti alloy was broken. An axial grain was formed through recrystallization, and the average grain size was approximately 80â¯Î¼m. With increasing annealing temperature, the grain size increased from 80â¯Î¼m to 150â¯Î¼m. The precipitates elongated to form band structures. During annealing, the band structure changed into several small grains enriched in the precipitates. Some short strip-like precipitates were distributed near the grain boundary irregularly. The two types of precipitates in the V-5Cr-5Ti alloy after hot forging were as follows: a) short-strip precipitate (VTi)2(CON) with FCC structure and lattice parameter of 0.4220-0.4259â¯nm and b) elliptical-shaped precipitate (VTi)2(CON) with FCC structure and lattice parameter of 0.4252-0.4347â¯nm. The two precipitate types during annealing were as follows. The first type was a rectangular precipitate (VTi)2(CO) with FCC structure and lattice parameter of 0.4186-0.4270â¯nm. The second type was an elliptical-shaped precipitate (VTi)5(CO) with FCC structure and lattice parameter of 0.4246-0.4344â¯nm.
