nethod for manufacturing a test bar from a turbo-machinery component, test bar made in accordance with the method, and turbo-machinery component associated with the method. A component section is obtained from the turbo-machinery component, wherein the component section includes a component portion, and wherein the component portion has a substantially rectangular cross section and has a width. First and second semi-circular cylinders are obtained having a diameter substantially equal to the width of the component portion. The component section is disposed between, and in contact with, the first and second semi-circular cylinders defining a component-section-cylinder assembly having first and second assembly ends. First and second end extensions are obtained. The first end extension is inertia welded to the first assembly end and the second end extension is inertia welded to the second assembly end defining a test-bar stock. The test-bar stock is machined creating the test bar.

A titanium-alloy article is produced by providing a workpiece of an alpha-beta titanium alloy having a beta-transus temperature, and thereafter mechanically working the workpiece at a mechanical-working temperature above the beta-transus temperature. The mechanically worked workpiece is solution heat treated at a solution-heat-treatment temperature of from about 175&#xb0; F. below the beta-transus temperature to about 25&#xb0; F. below the beta-transus temperature, quenched, overage heat treated at an overage-heat-treatment temperature of from about 400&#xb0; F. below the beta-transus temperature to about 275&#xb0; F. below the beta-transus temperature, and cooled from the overage-heat-treatment temperature.
