ABSTRACT:
The present invention provides (1) diffusion bonding methods for joining metallic materials like carbon steels or stainless steels,interposing a bonding material, such as 10 to 80 .mu.m thick Ni-based alloy with the melting point of 1150.degree. C. or lower,between base materials, heating so that the length heated at 800.degree. C. or above measures from 3 to 20 mm, in case of joining stainless steels a bonded layer, further, being heated between the both melting points, and applying the compressive stress, for example 0.5 to 2 kgf/mm.sup.2, so that a lateral expansion ratio is made within 1.0 to 1.1, and (2) a joined structure having the bonded joint formed thereby.
