Influence of the Parameters of a Laminated Structure on the Mechanical Properties of Titanium Alloys
Titanium alloys display a great variety of laminated structures. The mechanical properties of semi-finished products with such structures, ductility in particular, vary over a wide range.(1–3) Thus, for the two-phase alloys with a laminated structure. BT3-1, BT9, and others in an annealed state the reduction in area varies from very low values (5–10%) up to relatively high values (30–40%) approaching the ductility level of these alloys with globular structure. The difference in fatigue strength, fracture toughness, and other properties may also be significant (up to 25–30%) for various types of laminated structures.
