Effect of structural factors on the reversible 1,5-diketone — Hydroxydihydropyran conversion

It is shown that -bicyclanones with five-membered rings have less of a tendency to undergo conversion to cyclohemiacetals than the analogous compounds with six-membered rings.Communication XXVIII from the series Reactions of 1,5-Diketones. See [1] for communication XXVII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1315–1319, October, 1977.     

Elastoplastic properties of a low-modulus titanium-based β alloy

The elastoplastic properties (elastic modulus, amplitude-independent damping ratio, microplastic flow stress) of a Ti-26Nb-7Mo-12Zr titanium β alloy are determined using an acoustic resonance method. The effect of the strain during thermomechanical treatment on the structural features of the micro-crystalline alloy and, hence, its elastoplastic properties is analyzed.
