1. A system for forging a workpiece, the system comprising: a die;an alloy workpiece; anda pad positioned intermediate at least a portion of the die and at least a portion of the alloy workpiece, wherein the pad comprises a plurality of layers including: a first layer comprising a first thermal resistance and a first coefficient of friction, wherein the first layer comprises ceramic fibers;a second layer comprising a second thermal resistance and a second coefficient of friction; anda third layer comprising a third thermal resistance and a third coefficient of friction,wherein the second layer and the third layer each comprise fiberglass,the first thermal resistance is greater than the second thermal resistance and the third thermal resistance,the first coefficient of friction is greater than the second coefficient of friction and the third coefficient of friction,the second and third layers of the plurality of layers are secured together to form a sleeve, andthe first layer is positioned within the sleeve. 2. The system of claim 1, wherein the first layer comprises KAOWOOL. 3. The system of claim 1, wherein the first layer comprise fire clay fibers. 4. The system of claim 1, wherein the second layer further comprises a workpiece-contacting surface, and wherein the third layer further comprises a die-contacting surface. 5. The system of claim 1, wherein the alloy workpiece comprises one of an ingot, a billet, a bar, a plate, a tube, and a sintered pre-form. 6. The system of claim 1, wherein the alloy workpiece comprises a material selected from the group consisting of a nickel base alloy, a nickel base superalloy, an iron base alloy, a nickel-iron base alloy, a titanium base alloy, a titanium-nickel base alloy, and a cobalt base alloy. 7. The system of claim 6, wherein the alloy workpiece comprises a material selected from the group consisting of Alloy 718 (UNS No. N07718), Alloy 720 (UNS No. N07720), Rene 41 alloy (UNS No. N07041), Rene 65 alloy, Rene 88 alloy, WASPALOY® alloy (UNS No. N07001), and INCONEL®100 alloy. 8. The system of claim 1, wherein the die comprises an upset forging die and a punch, wherein the pad is positioned between at least a portion of the upset forging die and the alloy workpiece, wherein the system further comprises a second pad, and wherein the second pad is positioned between at least a portion of the punch and the alloy workpiece. 9. The system of claim 1, wherein the second and third layers of the plurality of layers are secured together by at least one fastener. 10. The system of claim 1, wherein the second and third layers of the plurality of layers are secured together by at least one of stitching or at least one staple.
