THE INVENTION CONCERNS A CRYSTALLOGRAPHICALLY TEXTURED METALLIC SUBSTRATE (1) INCLUDING A CONNECTION SURFACE (2) AND A SURFACE (3) INTENDED TO RECEIVE A THIN LAYER DEPOSIT, THE AFOREMENTIONED CRYSTALLOGRAPHICALLY TEXTURED METALLIC SUBSTRATE (1) BEING MADE UP OF AN ALLOY PRESENTING A CUBIC CRYSTALLINE SYSTEM WITH CENTRED FACES AND A PREDOMINANTLY CUBIC CRYSTALLOGRAPHIC TEXTURE {100} <001>, THE SURFACE INTENDED TO RECEIVE A THIN LAYER DEPOSIT (3) INCLUDING GRAINS (4) MAINLY PRESENTING CRYSTALLOGRAPHIC PLANES {100} PARALLEL TO THE SURFACE (3) INTENDED TO RECEIVE A THIN LAYER DEPOSIT. ACCORDING TO THE INVENTION, THE ALLOY IS AN IRON-NICKEL ALLOY WITH A COMPOSITION INCLUDING IN % IN WEIGHT RELATIVE TO THE TOTAL WEIGHT OF THE AFOREMENTIONED ALLOY: Ni ? 30%, Cu ? 15%, Cr ? 15%, Co ? 12%, Mn ? 5%, S < 0,0007%, P < 0,003 %, B < 0,0005 %, PB < 0,0001 %, THE PERCENTAGES IN NICKEL, CHROMIUM, COPPER, COBALT AND MANGANESE BEING SUCH THAT THE ALLOY SATISFIES THE FOLLOWING CONDITION: 34 % ? (Ni + Cr + Cu/2 + Co/2 + Mn), AND THE ALLOY INCLUDES UP TO 1% IN WEIGHT OF ONE OR SEVERAL DEOXIDISING ELEMENTS CHOSEN AMONG SILICON, MAGNESIUM, ALUMINIUM AND CALCIUM, THE REST OF THE ELEMENTS MAKING UP THE ALLOY BEING IRON AND IMPURITIES. |
