Patent ID: 7887748

Claim:
A solder material for soldering superalloy components having a directional microstructure, comprising: an alloy having alloy constituents that are the same as an alloy of the component and a proportion of an alloy constituent in the composition of the solder material modified relative to its proportion in the composition of the alloy of the component such that the melting temperature of the solder material is lowered relative to the melting temperature of the alloy of the component, wherein the alloy constituent includes at least one of the elements Al, Ti, Ta, Nb, and W, wherein the proportion of at least one of the elements Al and Ti is increased relative to the proportion in the superalloy and/or the proportion of the element W in the alloy of the solder material is reduced relative to its proportion in the superalloy; wherein the superalloy has the following composition: from 2 to 16 wt. % Cr from 0 to 15 wt. % Co from 0 to 3 wt. % Mo from 0 to 10 wt. % W from 0 to 12 wt. % Ta from 0 to 6 wt. % Re from 0 to 1 wt. % V from 0 to 0.5 wt. % Nb from 0.05 to 6.5 wt. % Al from 0 to 5 wt. % Ti from 0 to 0.2 wt. % Hf from 0 to 0.07 wt. % C remainder Ni, and the proportions of Al and/or Ta and/or Ti in the alloy of the solder material are increased relative to the composition of the superalloy.
