Structure of heat-resistant pseudo-α-titanium alloy and peculiarities of formation of structure of welded joints, produced by electron beam welding at a different beam focusing, were investigated. The ingot of experimental titanium alloy was melted by the method of electron beam crucible melting with a magnetic stirring. This method allows producing the homogeneous melt and ingots, homogeneous by chemical composition, after its cooling. Effect of beam parameters on shape and structure of weld metal, as well as resistance to cracking in the titanium heat-resistant alloy were studied. Mechanical properties of joints at different modes of electron beam welding of alloy, being investigated, were determined. Ref. 11, Tabl. 2, Fig. 8.
Key words: heat-resistant and titanium alloys; electron beam crucible melting; electromagnetic stirring; welded joint; ingot; structure; properties
