Title: Ductile alloys for sealing modular component interfaces

Abstract

A vane assembly (10) having: an airfoil (12) and a shroud (14) held together without metallurgical bonding there between; a channel (22) disposed circumferentially about the airfoil (12), between the airfoil (12) and the shroud (14); and a seal (20) disposed in the channel (22), wherein during operation of a turbine engine having the vane assembly (10) the seal (20) has a sufficient ductility such that a force generated on the seal (20) resulting from relative movement of the airfoil (12) and the shroud (14) is sufficient to plastically deform the seal (20).

  • Nickel aluminum alloys are welded utilizing a nickel based alloy containing zirconium but substantially free of titanium and niobium which reduces the tendency to crack.
  • The device is constituted by a seal-bearing ring disposed about the flange of the component and resting on the plate of the reactor, having a first set of annular seals ensuring sealing between the inner side surface of the sealbearing ring and the outer side surface of the flange of the component and a second set of annular seals ensuring sealing between the base surface of the seal-bearing ring and the plate of the primary vessel. The device also includes a means for applying a vertical force downwards on the seal bearing ring and a means of injecting an isolatingmore » gas between the flange of the component and the plate 1 of the primary vessel on which the component rests. The device is especially useful for sealed mounting of components within vessels of fast neutron nuclear reactors.« less
  • This patent describes tungstein-rich alloys of formula W{sub 100-P}M{sub X}RE{sub Y}ME{sub Z} wherein W is tungsten, M is one or more elements selected from the roup consisting of transition elements, RE is an element selected from the group consisting of rare earth and actinide elements, ME is silicon, boron, germanium or aluminum, X is 0 to 25 weight %, Y is 0 to 2 weight %, Z is 0.1 to 3 weight % and P = X + Y + Z where P {le} 26 weight %.
