Definitions

  • the invention relates to metallic materials based on martensitic steel, i.e., metallic materials constituted of a major portion of a steel of martensitic structure, the expression metallic material being taken here in a very general sense and including both semimanufactured products (sheet metal for example) and more fabricated products which have reached their final form from the industrial point of view (bars or tubes e.g.).
  • the invention relates also to methods of manufacture of such metallic materials based on martensitic steel.
  • Steels with martensitic structure, especially maraging" steels (generally containing nickel, cobalt and molybdenum, but no chromium), have high mechanical properties (breaking load capable of reaching 230 hec tobars), but, on the other hand, they are subject to corrosion phenomena by external agents and, especially, to the deleterious phenomenon of fragilization by hydrogen.
  • stainless steels of chrome-nickel even materials based on a nickel, have, in the austenitic phase, an excellent resistance to corrosion but properties distinctly less, from the mechanical point of view, than the steels of martensitic structure.
  • austenitic layer for convenience in the description, such a protective layer of austenitic structure will be denoted below by the expression austenitic layer, whether it relates to a stainless steel (especially chrome-nickel) or to a material based on nickel, even pure nickel.
  • the metallic material according to the invention is 'a massive ferrous material constituted by a regular alteraverage thickness of the adjacent austenitic layers situated respectively on both sides of the martensitic layer concerned,'the massive metallic material thus constituted having, due to its mixed austeno-martensitic stratified structure with predominance of martensite by weight, on the one hand, high mechanical properties (breaking load greater than hectobars) due to the predominance of the martensitic phase hardenable by intermetallic precipitation, on the other hand, an excellent resistance to corrosion and especially to fragilization by hydrogen, this resistance in depth of the material resulting from the presence of successive diffusion barriers constituted by the austenitic layers, and, on the other hand lastly, the qualities inherent in stratified materials with rigid layers (martensitic layers) separated by ductile layers (austenitic layers. of which the ductility is approximately five times greater than that of the martensitic layers).
  • the martensitic layers can all have a same thickness and the austenitic layers also a same thickness (less than the preceding one).
  • each martensitic layer in the majority of cases, it would be convenient to attribute to each martensitic layer, as already indicated, a thickness equal to at least five times, and preferably of the order of ten times, the average thickness of the two austenitic layers situated on both sides of the martensitic layer concerned.
  • the method according to the invention consists, with a view to obtaining the metallic material with alternated martensitic layers and austenitic layers which has just been considered,
  • this hardening treatment being preferably of the type of conventional hardening methods for maraging steels (e.g. a treatment for three hours at 480C).
  • FIG. 1 shows, in section with parts removed and with a considerable enlargement, a stratified composite sheet metal according to the invention.
  • FIGS. 2 and 3 show, under the same conditions as FIG. 1, a stratified composite bar and tube according to the invention.
  • the compositesheet metal illustrated in H0. 1 is formed of alternatedlayers of martensite M and austenite A. All the layers 'M have a same thickness E and all the layers A a same thickness e at least five times less than E and, preferably, of the order of one tenth of E.
  • a composite sheet metal according to the invention can be obtained from a simple stack of sheets of maraging steel having a layer of nickel on their two faces.
  • the outer surfaces of the sheet metal are preferably formed by austenitic layers, i.e., by the lay-- ers more adapted to resisting corrosion.
  • FIG. 2 shows a bar or rod formed of alternated coaxial layers of martensite M and austenite A, the martensite being predominant from the weight point of view and the respective thicknesses E and e of the layers M and A being advantageously able to satisfy the dimensional criteria explained previously, in a general form, relative to the abovesaid thicknesses.
  • Such a bar could be used for the reinforcement of concrete and, whatever its application, it would be advantageous to make it include an austenitic outer layer Al in order to protect it against corrosion by environmental agents.
  • FIG. 3 finally, shows a tube formed of alternated coaxial layers of martensite M and of austenite A, the respective thicknesses E and e of the said layers being able, this time again, to satisfy the abovesaid dimensional criteria.
  • Such tube could be suitable for channeling gas or destructive liquids under pressure and it would then be advantageous to make it include an inner wall A0 of austenitic structure, its outer wall Al being also able to be austenitic, especially if there is risk of destruction from the outside.
  • the fields of application of the composite elements according to the invention are multiple and there can be mentioned, especially, the fields of aerospace technology and of chemical and nuclear engineering.
  • Massive ferrous metallic material having high me chanical strength and resistance in depth of the material to hydrogen embrittlement consisting essentially of a regular alternation of a plurality of layers of martensitic steel and of layers of austenitic structure having a resistance to corrosion higher and a mechanical resistance lower than those of said martensitic steel, the thickness of each martensitic layer being of a magnitude equal to at least five times the average thickness of the adjacent austenitic layers situated respectively on both sides of the martensitic layer concerned.
  • each of the martensitic layers have the same thickness and .each of the austenitic layers have the same thickness.
  • Iron base material according to claim 1 wherein said layers of austenitic structure are of a material selected from the group consisting of Cr. Ni. austenitic steels, nickel and nickel-base alloys.
