A method of fabricating a Ti-6Al-4V titanium alloy component including solution heat treating a forged Ti-6Al-4V titanium alloy component at a temperature within the alpha+beta two-phase field for the material of the component for a predetermined period of time, and subsequently cooling the component. The component is then age heat treated using an overaging process at a predetermined overaging temperature for a predetermined time, and the component is cooled to room temperature. The overaging temperature is selected to be a higher temperature than an aging heat treatment temperature for effecting a maximum yield strength in the component.

Solution heat treatment and overage heat treatment for titanium components

A method of forming a thermocouple (), including: depositing a first material on a component () to form a first leg (); depositing a second material through a mask () to form a pattern () on the component (), the pattern () forming a plurality of discrete second leg junction ends () and a continuous patch () of the second material comprising indiscrete lead ends of the second legs (), each second leg junction end () spanning from a respective junction () with the first leg () to the continuous patch (); and laser-ablating the continuous patch () to form discrete lead ends () of the second legs (), each lead end () electrically connected to a respective junction end (), thereby forming discrete second legs ().
