چکیده
A solid-phase diffusion welding of coarse-grained and ultrafine-grained (UFG) specimens titanium near-α alloy Ti-5Al-2V used in nuclear power engineering was made by Spark Plasma Sintering. The failure the welded conditions hot salt corrosion electrochemical shown to have a preferentially intercrystalline character. In case presence macrodefects, crevice joints observed. resistance alloys against found be determined concentration vanadium at grain boundaries, size volume fraction β-phase particles, micro- macropores joints. UFG are harder higher corrosion.
