Abstract
A method of thermomechanically forming, for example forging, rolling, extruding or drawing, an article from a precursor thereof, is described. The method comprises: providing the precursor, for example an ingot, a forging stock, a forging, a bar, a billet or a plate, comprising, substantially comprising, essentially comprising and/or consisting of an α+β Ti alloy having a beta transus temperature β, wherein the precursor defines a set of portions including a first portion; and thermomechanically forming the article from the precursor by heating the first portion and deforming the heated first portion by a total true strain ε, wherein the total true strain εis greater than a predetermined threshold true strain ε; wherein thermomechanically forming the article from the precursor comprises i iterations of: (a) heating the first portion to a temperature Tduring a time twherein the temperature Tis at most the beta transus temperature β; (b) deforming the heated first portion by a true strain ε, wherein the true strain εis at most the predetermined threshold true strain εand (c) repeating steps (a) and (b) until the cumulative true strain ε=Σeu is the total true strain εwherein i is a natural number greater than or equal to 2.
