Effect of Thermohydrogen Treatment on the Structure and Properties of Titanium Alloy Castings

Metal Science and Heat Treatment -     

Raising the accuracy of operative monitoring by using a variable pressure differential of the flow rate of material and energy carriers in the liquid and gaseous states

Means are considered for reducing the systematic errors in calculating the flow rate of material. For operative monitoring of the day- to- day flow rate, a comparative analysis is made of the numerical solution of the mass flow rate equation and the structure- generalized method for solving the equation.Translated from Izmeritel'naya Tekhnika, No. 5, pp. 37–39, May, 1994.     

Structure and internal-stress formation in VT20 titanium-alloy welded joints

Microstructure, texture, and microhardness and residual-stress distributions are studied in a VT20 alloy welded shell consisting of two coaxial nested components connected by a circular weld.
