Definitions

  • the invention relates to a heat treatment process for material bodies Nickel-based superalloys according to the preamble of the first claim.
  • Such heat treatment methods for material bodies made of nickel-based superalloys are known from US 4,643,782.
  • nickel-based superalloys with the trade name "CMSX” are described, from which single-crystal components can be produced using the casting process, in particular blades for gas turbines.
  • CMSX-4" essentially consists of (in% by weight): 9.3-10.0 Co, 6.4-6.8 Cr, 0.5-0.7 Mo, 6.2-6.6 W, 6.3 -6.7 Ta, 5.45-5.75 Al, 0.8-1.2 Ti, 0.07-0.12 Hf, 2.8-3.2 Re, balance nickel.
  • CCSX-4 essentially consists of (in% by weight): 9.3-10.0 Co, 6.4-6.8 Cr, 0.5-0.7 Mo, 6.2-6.6 W, 6.3 -6.7 Ta, 5.45-5.75 Al, 0.8-1.2 Ti, 0.07-0.12 Hf, 2.8-3.2 Re, balance nickel.
  • the invention has for its object in a heat treatment process for material bodies made of nickel-based superalloys of the aforementioned It is a way of creating a homogeneous, stable structure with a high creep and fatigue strength and has good aging properties.
  • the heat treatment of the material body includes the following steps: annealing at 850 ° C to 1100 ° C, heating to 1200 ° C, heat from 1200 ° C to 1300 ° C with a heating rate lower equal to 1 ° C / min, a multi-stage homogenization and solution process a temperature of 1300 ° C ⁇ T ⁇ 1315 ° C.
  • FIG. 4 schematically shows a particularly advantageous embodiment of the inventive Heat treatment process represented by the time t against the temperature T is plotted.
