Description
Technical field
The present invention relates to crisp in technical field of metal material heat treatment more particularly to a kind of laser repairing nickel base superalloy
The removing method of property phase.
Background technique
Nickel base superalloy is because having excellent comprehensive performance such as yield strength, tensile strength, creep resistant in higher temperature
Ability, good anti-oxidant, corrosion-resistant, radiation resistance etc. are widely used in the neck such as aerospace, nuclear energy, petroleum, automobile
Domain.As a kind of important engineering material, nickel base superalloy is chiefly used in environment and the military service items such as high temperature, high pressure, burn into vibration
Part stringent case, and the materials'use for preparing as key part, part difficulty of processing is big, and value is high.Zero during military service
The loss of part is inevitable, and for nickel base superalloy part, the replacement cost after damage is high.Therefore, to damage
Part after wound is repaired and is used for multiple times, and the means that people generally use for save the cost are become.
Laser repairing is using laser as high energy heat source, filled silk to the metal parts damaged, powdering or powder feeding it is fast
Rapid-result shape recovery technique.The technology is and even tissue after repairing, thin since the liquid metal cooling rate of laser cladding is fast
Small, consistency with higher is widely used in the reparation of nickel base superalloy.But since nickel base superalloy is added to perhaps
More alloying elements are quickly cooled down in process of setting in laser repairing molten bath and are easy to happen microsegregation, can be precipitated in interdendritic crisp
Hard Laves phase, leads to the mechanical properties decreases such as impact property and the plasticity of alloy.
Currently, in the laser repairing nickel base superalloy generallyd use the removing method of brittleness Laves phase mainly have it is following
Two kinds.The first is higher temperature solid solution, i.e., in the at a temperature of long-time heat preservation higher than 1100 DEG C, closes Nb, Mo of segregation etc.
Gold element is sufficiently spread, to achieve the purpose that eliminate brittleness Laves phase.But such method heat treatment temperature is high, can be to workpiece
Thermal damage is caused, makes material grains roughening and precipitation phase solid solution, irreversible shadow is generated to alloy structure and mechanical property
It rings.Second is to take measures to be controlled the formation of Laves phase in forming repair process, and adoptable measure includes molten
Pond is quickly cooled down, applies electromagnetic agitation etc. to molten bath.But from the point of view of control effect, these ancillary measures are to Laves phase control
Effect it is limited, though its volume fraction can be reduced to a certain extent, still can not achieve disappearing completely for Laves brittlement phase
It removes, the material mechanical performance after reparation is still affected.
