Vacuum brazing tests were carried out on the age-hardened steel of the 14-5 PH type using the 82Au i 18Ni solder. It has been found that the joint has a multilayer structure and it consists of two kinds of Au-Ni solid solutions: one is rich in gold and the other - rich in nickel. The influence of roughness of the surfaces to be joined and the distance between them on the joint strength have been determined. The maximum tensile strength (Rm = 1257 MN/m2) was obtained for the joints of polished surfaces without any distances elements, brazed in the temperature 1273 K for 20 minutes and then aged in the temperature 723 K for 120 minutes.
