1.The addition of 0.3–0.5% H to alloy VT6 made it possible to reduce the temperature of forging blanks from 950 to 750°C without increasing the forming force.2.Hydrogenation brings about the formation of a?-martensite in the structure of alloy VT6. After hydrogenation no reduction of the grain size was found.3.The type of structure obtained in the alloy after dehydrogenation at the given temperature is determined by the deformation temperature in the hydrogenated state. Deformation in the ß-range brings about the formation of a lamellar structure in the alloy VT6, and at temperatures close to tmp it makes it possible to obtain, with the same regime, a dehydrogenated mixed or globular structure.4.When forging blanks are made of alloy VT6, the application of a technology including reversible alloying with hydrogen and deformation (OLVOD) makes it possible to enhance ductility considerably without impairing the strength properties. To obtain the optimal complex of mechanical properties, alloy VT6 with 0.3–0.5% H has to be forged at -800°C. |
