Relationship Between Structure and Properties of the Large-Size Billet of Titanium Alloy PT-7M

KnE Engineering / XIX International scientific-technical conference “The Ural school-seminar of metal scientists-young researchers” / Pages 267–274

Abstract

In this paper the interrelation between the structure, hardness and strain resistance at 875 ∘C of the hot-forged pipe billet of the titanium alloy PT-7M (Ti-2.2Al-2.5Zr) was studied by the methods of macro, micro, XRDA, durometric analyzes and hot upsetting operation at 875 ∘C. It was found, that the volume fraction of the large grains reduced and recrystallized from the center to the surface of the pipe billet. As a result, hardness and strain resistance grew at 875 ∘C from the center to the surface of the billet.


 


 


Keywords: titanium alloy PT-7M, hot deformation, phase composition, structure, texture, hardness, strain resistance.
