The invention claimed is: 1. A piston ring comprising a piston ring substrate, wherein said piston ring substrate comprises at least 50 volume %, of intermetallic alloy, based on the total volume of the piston ring substrate, wherein the intermetallic alloy is a mixture of NiAl and Ni3Al. 2. The piston ring according to claim 1, wherein said piston ring substrate comprises at least 70 volume % of the intermetallic alloy, based on the total volume of the piston ring substrate. 3. The piston ring according to claim 1, which comprises a coating on said piston ring substrate. 4. The piston ring according to claim 3, wherein said coating of said piston ring substrate comprises at least one intermetallic alloy. 5. The piston ring according to claim 3, wherein the coating forms an outer surface of the piston ring. 6. The piston ring according to claim 3, which consists of the substrate and coating. 7. The piston ring according to claim 1, which has an inner diameter of at least 180 mm. 8. The piston ring according to claim 1, wherein the substrate comprises a matrix formed by at least one of NiAl and Ni 3Al, a hard phase and a mixed zone around the hard phase. 9. The piston ring according to claim 1, which consists of the substrate. 10. A piston ring, comprising: a piston ring substrate which comprises at least 50 volume % of intermetallic alloy, based on the total volume of the piston ring substrate; wherein: the piston ring substrate is a casting; and the intermetallic alloy is a mixture of NiAl and Ni3 Al. 11. The piston ring according to claim 10, wherein the piston ring substrate comprises at least 70 volume % of the intermetallic alloy, based on the total volume of the piston ring substrate. 12. The piston ring according to claim 10, which comprises a coating on the piston ring substrate. 13. The piston ring according to claim 12, wherein the coating comprises at least one intermetallic alloy. 14. The piston ring according to claim 12, wherein the coating forms an outer surface of the piston ring. 15. The piston ring according to claim 10, which has an inner diameter of at least 180 mm. 16. The piston ring according to claim 10, wherein the substrate comprises a matrix formed by at least one of NiAl and Ni 3Al, a hard phase and a mixed zone around the hard phase. 17. A piston ring, comprising: a piston ring substrate which comprises at least 50 volume % of intermetallic alloy, based on the total volume of the piston ring substrate wherein: the intermetallic alloy is a mixture of NiAl and Ni3 Al; and the piston ring does not have a coating on the substrate. 18. The piston ring according to claim 17, wherein the piston ring substrate comprises at least 70 volume % of the intermetallic alloy based on the total volume of the piston ring substrate. 19. The piston ring according to claim 17, which has an inner diameter of at least 180 mm. 20. The piston ring according to claim 17, wherein the substrate comprises a matrix formed by at least one of NiAl and Ni 3Al, a hard phase and a mixed zone around the hard phase.
