Abstract: The present invention is a clad material for an electric contact, including a base material composed of a Cu-based, precipitation-type age-hardening material, and a contact material composed of an Ag alloy bonded to the base material. On a bonded interface between the contact material and the base material, a width of a diffusion region including Ag and Cu is 2.0 ?m or shorter. The clad material is produced by bonding each other the contact material and the base material having undergone solutionizing and age-hardening beforehand, suppressing the diffusion region from expanding after bonding. The present invention is capable of providing an electric contact, which achieves higher conductivity, without sacrificing property of the Cu-based, precipitation-type age-hardening material.

Abstract: A first image before deformation and a second image after deformation are input and formed into polygon models represented with a polygon mesh by a polygon model generation processing part. Polygon reduction processing is performed by a low progression level polygon model generation processing part to generate low progression level polygon models having a reduced number of polygons and metadata containing the reduction process of the number of polygons. A low progression level polygon model morphing processing part specifies corresponding vertices between the low progression level polygon models, and then they are formed into intermediate low progression level polygon models by interpolation. Intermediate images are generated by reproducing processing to the polygon model using the metadata by an intermediate image generation processing part and texture mapping.
