High temperature bending tests and high temperature tensile tests of the mild steels in contact with various liquid Cu-Pb alloys were examined, and the dihedral angles of γ iron/Cu-Pb liquids in equilibrium condition at high temperature were measured. As copper percentage in the liquid Cu-Pb alloys increased, the steels in contact with the liquid alloys became more brittle, that is, the surface cracking of the steels by high temperature bending became severe, and tensile strength & elongation of the steels in high-temperature tensile tests decreased. The dihedral angles of γ iron/liquid fell down to 20℃. These relation was investigated. And the fracture streses estimated roughly from dihedral angles were compared with the stresses obtained from tensile tests.
