Metal Science and Heat Treatment Aims and scope

Abstract

The phenomena of brittleness of structural α-pseudo-α- and (α + β)-titanium alloys are analyzed and generalized using the results of tests of rupture specimens and various parts. The characteristics of ductility (elongation δ and contraction Ψ) are used for evaluating the macroscopic manifestations of embrittlement, and the appearance of fracture surfaces as observed in electron microscopic diffraction patterns is used for estimating the micromanifestations of embrittlement.
