A MATERIAL ON THE BASIS OF A CrNi ALLOY, A SEMI-FINISHED PRODUCT, COMPONENTS FOR A COMBUSTION ENGINE, AND ALSO A METHOD FOR THE MANUFACTURE OF THE MATERIAL AND OF THE SEMI-FINISHED PRODUCT

摘要

The present invention is a combustion engine, in particular, relates to a CrNi alloy material as a base material used in the production of semi-finished product as a starting material for forming the component (1) of a large diesel engine, the material has a chemical composition: ; [Cr. _x. Ni. _y. A. _z. ] N. _k. , Wherein x + y + z + k = 100%, ; Component A. _z. Is La, Ce, Y, Hf, Sc, Si, C, S, P, Al, Zr, B, Mo, Fe, Mn, O, and rare earth is at least one element selected from the group of chemical elements consisting of . The Cr- content of the material is in weight% 50% x 100%, Ni- and the amount of the material is in weight% y 0%, component in the material A. _z. By weight and the content of the% 0% z 50%. According to the invention, the nitrogen content of the material is in weight% 0.01% k 0.1%. The present invention also made of a semi-finished material according to the present invention, and the semi-finished product is manufactured from, to a component (1) for a combustion engine. The present invention also relates to a method of producing a material by isostatic compression process, and a method of manufacturing a semi-finished product. ; CrNi alloys, semi-finished products, isostatic compression, the nozzle head, notched bar impact value.
