1. A method for making a tube, the method comprising: providing a hollow first cylinder comprising zirconium or a zirconium alloy, the first cylinder having an outer surface;providing a hollow second cylinder comprising titanium or a titanium alloy, the second cylinder having an inner surface, where
1. A method for making a tube, the method comprising: providing a hollow first cylinder comprising zirconium or a zirconium alloy, the first cylinder having an outer surface;providing a hollow second cylinder comprising titanium or a titanium alloy, the second cylinder having an inner surface, wherein the first cylinder can fit within the second cylinder;positioning the first cylinder within the second cylinder, wherein the outer surface of the first cylinder opposes the inner surface of the second cylinder;welding together end joints between the first cylinder and the second cylinder to provide a multi-layer billet;induction heating the multi-layer billet to an extrusion temperature;extruding the heated multi-layer billet, thereby metallurgically bonding the outer surface of the first cylinder to the inner surface of the second cylinder, and providing a tube having a wall comprising an inner layer comprising zirconium or a zirconium alloy metallurgically bonded to an outer layer comprising titanium or a titanium alloy; andcold working the tube to reduce the wall thickness and/or diameter of the tube. 2. The method of claim 1, wherein the tube lacks an interdiffusion layer between the inner layer and the outer layer. 3. The method of claim 1, wherein the tube lacks intermetallic compounds and alloying in the metallurgical bond between the inner layer and the outer layer. 4. The method of claim 1, wherein cold working the tube comprises cold pilgering the tube. 5. The method of claim 1, wherein cold working the tube comprises cold pilgering the tube to a reduction in area of 20% to 90%. 6. The method of claim 1, wherein cold working the tube comprises cold drawing the tube. 7. The method of claim 1, further comprising heat treating the tube after extruding the multi-layer billet and/or after cold working the tube. 8. The method of claim 7, wherein heat treating the tube comprises annealing the tube at a temperature in the range of 500° C. to 750° C. for 1 to 12 hours. 9. The method of claim 1, wherein cold working the tube comprises at least two cold pilgering passes, wherein the tube is annealed at a temperature in the range of 500° C. to 750° C. for 1 to 12 hours after each pilgering pass and before any subsequent pilgering pass. 10. The method of claim 1, comprising extruding the billet in an extrusion apparatus comprising an extrusion ram that is advanced at a rate in the range of 50 mm/minute to 900 mm/minute during an extrusion cycle. 11. The method of claim 1, comprising extruding the billet at an extrusion ratio in the range of 3:1 to 30:1. 12. The method of claim 1, wherein the multi-layer billet is induction heated to a temperature in the range of 550° C. to 900° C. 13. The method of claim 1, wherein the end joints are welded together with an electron beam weld. 14. The method of claim 13, wherein the electron beam weld penetrates the end joints to a depth ranging from 5 mm to 50 mm. 15. The method of claim 1, further comprising reducing surface roughness of at least one of the outer surface of the first cylinder and the inner surface of the second cylinder to no greater than 63 micro-inches RA before positioning the first cylinder within the second cylinder. 16. The method of claim 1, further comprising ice blasting at least one of the outer surface of the first cylinder and the inner surface the second cylinder by propelling crystalline water against the surface(s), thereby mechanically scrubbing and liquid flushing the surface(s). 17. The method of claim 1, further comprising inertia welding a zirconium or zirconium alloy tube segment to the tube having a wall comprising an inner layer comprising zirconium or a zirconium alloy metallurgically bonded to an outer layer comprising titanium or a titanium alloy. 18. A method for making a tube, the method comprising: providing a hollow first cylinder comprising zirconium, a zirconium alloy, hafnium, a hafnium alloy, vanadium, a vanadium alloy, niobium, a niobium alloy, tantalum, or a tantalum alloy, the first cylinder having an outer surface;providing a hollow second cylinder comprising stainless steel, titanium, or a titanium alloy, the second cylinder having an inner surface, wherein the first cylinder can fit within the second cylinder;positioning the first cylinder within the second cylinder, wherein the outer surface of the first cylinder opposes the inner surface of the second cylinder;welding together end joints between the first cylinder and the second cylinder to provide a multi-layer billet;heating the multi-layer billet to an extrusion temperature;extruding the heated multi-layer billet, thereby metallurgically bonding the outer surface of the first cylinder to the inner surface of the second cylinder, and providing a tube having a wall comprising an inner layer metallurgically bonded to an outer layer; andcold working the tube to reduce the wall thickness and/or diameter of the tube. 19. The method of claim 18, wherein cold working the tube comprises cold pilgering the tube to a reduction in area of 20% to 90%. 20. The method of claim 18, further comprising annealing the tube at a temperature in the range of 500° C. to 750° C. for 1 to 12 hours, wherein the annealing is performed after extruding the multi-layer billet and/or after cold working the tube. 21. The method of claim 18, comprising extruding the billet at an extrusion ratio in the range of 3:1 to 30:1 in an extrusion apparatus comprising an extrusion ram that is advanced at a rate in the range of 50 mm/minute to 900 mm/minute during an extrusion cycle. 22. The method of claim 18, wherein the multi-layer billet is induction heated to a temperature in the range of 550° C. to 900° C. 23. The method of claim 18, wherein the end joints are welded together with an electron beam weld that penetrates the end joints to a depth ranging from 5 mm to 50 mm. 24. The method of claim 18, further comprising reducing surface roughness of at least one of the outer surface of the first cylinder and the inner surface of the second cylinder to no greater than 63 micro-inches RA before positioning the first cylinder within the second cylinder. 25. The method of claim 18, further comprising ice blasting at least one of the outer surface of the first cylinder and the inner surface the second cylinder by propelling crystalline water against the surface(s), thereby mechanically scrubbing and liquid flushing the surface(s). 26.
