- Abstract
In this work the possibility of using brazing alloys with the structure of a solid solution based on Cu–Mn–Ni system for brazing dissimilar joints of molybdenum-stainless steel was shown, the results of micro X-ray spectrum examinations and strength characteristics of brazed joints were presented. The micro X-ray spectrum examinations revealed that in producing dissimilar joints of molybdenum-stainless steel using brazing alloys based on Cu–Mn–Ni system the central zone of a brazed weld is composed of a solid solution on copper base. The diffusion zone of weld (on the side of molybdenum) is formed by the phase based on molybdenum, which is precipitated in the form of a continuous band along the brazed weld. The application of brazing alloy based on Cu–Mn–Ni system with the structure of a solid solution provides formation of dense brazed welds without cracks. The shear strength is at the level of 200–210 MPa during fracture in the brazed weld and at 300 MPa during fracture in the base metal (molybdenum).
