Abstract

A Ti-48Al-2Cr-2Nb alloy was prepared by electron beam smelting. The effect of solution parameters on the microstructures, constituent phases and hardness was studied. The results show that impurities in the alloy could be significantly removed after electron beam smelting. The content of O and N in the ingot after smelting is about 93.25 and 25.75 ppmw, respectively. The average grain size of the ingot is 250 μm, and the lamellar spacing varies from 40 to 200 nm. As the solution temperature increases, the microstructure is coarsened obviously, accompanied with the increase in lamellar spacing. The lamellar spacing, the grain size and the microhardness of the alloy increase gradually as the solution time increases. When the alloy is solution treated at 1320 °C for 30 min, a uniform microstructure can be acquired, whose grain size is about 500 μm with an average lamellar spacing of 200 nm. The microhardness of the alloy after optimized heat treatment is 400HV.
