摘要

The microstructure evolution of laser multi-layer deposited Ti-XAl-YV (X (11, Y (10, mass fraction, %, similarly hereinafter) alloys from blended elemental powders with the content of Al and V was studied. Results show that the size and quantity of (colony in the prior (grains are decreased gradually with the increase of Al and V, and the microstructure in prior (grains changes from widmanstätten structure to basketweave structure with the (laths and (phase braided. Meanwhile, the size and aspect ratio of (laths are decreased obviously. The nucleation and growth conditions of (phase in single-line laser multi-layer deposited Ti-XAl-YV alloys were analyzed and the microstructure evolution mechanism was revealed on the basis of thermal history modeling, (→ (transformation temperature computation and the phase diagram analysis of Ti-XAl-YV alloys.
