Investigation of the effect of aluminum on the phase composition of Ti–Al–Nb–Mo gamma alloys

A quantitative analysis of the influence of aluminum concentration on the phase composition of TNM-type Ti–Al–Nb–Mo γ-alloys has been carried out using the Thermo-Calc software and experimental methods. Isothermal and polythermal sections of the corresponding phase diagram have been calculated; the critical temperatures of phase transformations in the alloys of the system, and the chemical compositions of phases formed in them (β, α, α₂, γ) have been determined. The influence of the annealing temperature on the microstructure and phase composition of the alloys containing 43 and 40% Al has been studied.

A method of assessing the environment-population health system

Parameters were studied characterising the system of blood aggregate state control (BASC) in 693 patients with chronic gastritis and duodenitis. Suggested in the paper are six variants of the hemocoagulation and fibrinolysis inadequacy, such as latent hypercoagulation (a decline in spontaneous fibrinolysis), manifest hypercoagulation (enhanced tolerability of plasma to heparin), isolated paracoagulation (positive fibrinogen B or ethanol test), latent hypocoagulation (clot retraction is reduced or levels of fibrinogen are raised), structural hypocoagulation (spontaneous fibrinolysis is on the increase), manifest hypocoagulation (lowered tolerance of plasma to heparin). An algorithm of the BASC system is submitted allowing the diagnosis to be rendered automatic and differentiated therapy treatments to be prescribed.
