Statistical investigation of mechanical properties of VT6 alloy bars with globular-lamellar structure

Regularities in the joint influence of the chemical composition and parameters of the globular-lamellar structure of VT6 alloy on the mechanical properties of rolled bars on its basis after annealing in various modes are studied. The conducted correlation analysis found that fluctuations in the grade composition of samples in terms of aluminum and molybdenum equivalent values have a more significant effect on their mechanical properties than the structural factor. A model for forecasting the ultimate strength of annealed bars with a diameter of 15–90 mm is developed, taking the chemical composition and parameters of the globular-lamellar structure into account.
