The ultimate tensile strength of the brazed butt joints is comparable to that of common superalloy repair materials, but the presence of boride par- ticles tends to slightly lower ductility and tensile strength.
With Mar M 247-3, the ultimate tensile strength is determined to be 770 MPa at 21C, reducing to 340 MPa at 927C.
