Definitions

  • the invention relates to alloys based on AI, essentially containing Ni and / or Fe, Si as main alloying elements obtained in the essentially amorphous state, by relatively rapid solidification.
  • essentially amorphous is meant an alloy in which the crystallized volume fraction is at most equal to 25%.
  • alloys according to the invention contain (in atom%): (Ni) can be partially substituted by Fe up to 10% by V or B (up to 5 at.%) or completely by Mn (up to 22% at.%), the rest being consisting of AI and the usual processing impurities.
  • the alloys preferably contain: manganese being limited to 5 at. %.
  • alloys exhibit a set of remarkable properties in the amorphous or essentially amorphous state as well as in the microcrystallized state obtained by annealing of the amorphous or essentially amorphous state. These properties result from the introduction of a large quantity of alloying elements without rhedibitory effects of segregation or of the formation of fragile intermetallic phases of dimensions greater than 10 ⁇ m.
  • the unique combination of compositions and structures thus obtained gives these alloys high hardnesses, excellent heat stability for long-term annealing as well as special tribological properties.
  • a consolidation process consists of grinding the ribbons obtained by casting on a wheel, sieving below 100 ⁇ m, hot compression between 350 and 400 ° C and hot spinning around 400-450 ° C. It is thus possible to obtain massive products.
  • FIG. 5 shows the evolution of the Vickers microhardness under 10 g of the ribbons measured at 20 ° C. after isothermal annealing for one hour at different temperatures.
  • crystallization is accompanied by a significant increase in hardness.
  • the high levels of microhardness obtained (300 HV to 560 HV).
  • the alloy consists of micrograins of AI, of Si and of phase AI 3 Ni orthorhombic equilibrium.
  • the optical and transmission electron microscopy examinations show that after maintaining one hour at 400 ° C, the average grain size is between 0.05 ⁇ m and 0.5 ⁇ m. This very fine microcrystalline structure can only be obtained for such compositions by annealing an amorphous alloy and gives the alloy both mechanical strengths and high ductilities.
  • the essentially amorphous alloy according to the invention therefore exhibits very good friction and abrasion behavior.
