Patent ID: 7946471

Claim:
A method for cohesively joining a joining location made from a base material using a brazing composition, the method comprising: subjecting the joining location provided with the brazing composition to a first heat treatment at a first temperature selected such that an initial phase melts; and subjecting the joining location provided with the brazing composition to a second heat treatment using a second temperature which is below a first solidus temperature of the base material with a result that the melted initial phase together with the base material and/or the initial phase together with a further initial phase forms a resultant phase, wherein the brazing composition comprises: the base material with the first solidus temperature, and the initial phase with a second solidus temperature, wherein the second solidus temperature is below the first solidus temperature, wherein the initial phase is selected so that a resultant phase is formed, wherein during a heat treatment above a specific temperature and when the initial phase is together with the base material and/or the initial phase is together with a further initial phase, a third solidus temperature of the resultant phase is higher than the second solidus temperature or a fourth solidus phase of the further initial phase, and wherein the base material comprises nickel and the initial phase is aluminum.
