Effects of electroshock treatment on microstructure evolution and mechanical properties of Ti−8Al−1Mo−1V alloy

• Electroshock treatment (EST) induces phase transformation from acicular secondary αs to β phase in Ti−8Al−1Mo−1V alloy, with precipitation of acicular martensitic phase (αM) at 0.12 s. • EST refines the average grain size from 3.95 μm to 2.53 μm, accompanied by significant recrystallization and martensitic transformation. • EST leads to a more uniform texture distribution due to crystal orientation variations after phase transformation. • EST significantly enhances yield strength while reducing fracture strain, primarily attributed to martensitic phase precipitation.
