Abstract
Structural-phase transformations in specimens of electron beam welded joints on two experimental heat-resistant pseudo- a and a + b multi-component titanium alloys containing silicon additions were investigated. Specific (differentiated) contributions of different types of structures and phase formations in the near-weld zone to strength values and distribution of local internal stresses in the welding zones under investigation were analytically estimated.
Keywords: heat-resistant titanium alloy, structural state, phase formations, microdiffraction reflections, strength characteristics, local internal stresses
