... 250 MPa (35 ksi) ( Ref 38 ). The high tensile strength of the joint is due to the mechanical constraint provided by the stronger base metal, which restricts transverse contraction of the interlayer ( Ref 36 , 37 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ). The constraint establishes radial (triaxial...
