| Abstract: | We study the regularities of formation of homogeneous lamellar structures in (α + β)-titanium alloys subjected to thermal treatment and gradient structures with fine lamellar α-phase in the surface layers in the course of thermal hydrogen treatment. We determine the structure of alloys in different states, their phase compositions, Rockwell hardness, and impact toughness. It is experimentally demonstrated that the decrease in the cooling rate from the β-region of the samples of VT23 alloy from 5 down to 0.01 K/sec leads to an increase in the mean thickness of the α-phase lamellae from 1.2 μm (initial state) up to 8 μm in the course of cooling with isothermal holdings in the (α + β)-region. In this case, the impact strength increases from 0.15 up to 0.68 MJ/m2.We propose a scheme and modes of thermal hydrogen treatment of the rods of VT6 alloy guaranteeing the formation of a gradient structure with finely lamellar α-phase in the surface layer and a bimodal (α + β)-structure in the core. The hardness of the alloy in this structural state gradually changes from 39 HRC (rod surface) down to 32 HRC (core). [ABSTRACT FROM AUTHOR] |
