The paper studies the evolution of the structure, phase composition, and impact toughness of the VT 8 alloy after two types of processing including helical rolling and water quenching. It is worth noting that in the latter type of the alloy processing, the additional air quenching is used between the rolling and quenching processes. It is shown that after both processing types, a bimodal structure formation occurs in the alloy, namely α-Ti particles in the β-matrix. The obtained alloy structure is analyzed; the grain size and shape effect on the impact toughness and hardness of the VT 8 alloy is considered herein.
