Study on Processing Technology of Ta40Nb Alloy Sheet for Chemical Anticorrosion

The Ta40Nb alloy ingot is obtained by using electron beam melting.Ta40Nb alloy forging and heat treatment process was studied, the results show that " the axial upsetting radial long pull + three circular upsetting long pull" rolling technology of forging process, large working rate of breakdown, can more fully broken Ta40Nb alloy as-cast organization, alloy plate has a fine uniform cubic.Ta40Nb alloy plate product processing using 1 200 ℃ ×90 min of heat treatment process, can make the material eventually get uniform, fine isometric organization, grain size reaches more than 8.
