Claim Text:
1. A method for joining materials, comprising: (a) providing a first component, wherein the first component includes a first alloy having a known austenization temperature below which martensite forms when the component is heated and then cooled at a predetermined rate of cooling; (b) providing a second component, wherein the second component includes a second alloy, and wherein the second component is a hex stud that further includes C464 brass; and (c) utilizing a welding apparatus to create a weld between the first and second components without crossing the austenization temperature of the first alloy and forming martensite therein, wherein the welding apparatus is an inertia friction welding machine, and wherein the inertia friction welding machine operates at a speed of 4000-4500 rpms, an inertial mass of 1.21 WK
