The tensile strength of joints increased through a maximum at 100 μm thickness of Ni foil. Beyond100 μm however, the strength of the joint was almost independent of the thickness of Ni foil. The improvement of the bonding strength was interpreted by the decrease of the thermal stress which is due to the difference in the coefficients of thermal expansion of the hard metal and the steel during the cooling of the joints. Thermal stresses have been estimated by the theory of thermal elastic analysis based on the finite element method.}, pages = {71--85}, title = {Ni箔をインサート材としたWC-Co系超硬合金と鉄鋼の拡散接合}, volume = {41}, year = {1991}, yomi = {モモノ, タダシ and デガワ, ノブユキ and カタヤマ, ヒロシ and シバタ, イサオ and ミナト, ヨシヒロ and カナヤマ, タツヤ and ヤマグチ, カズヒロ and サカイ, マサヒロ and マキノ, イサオ and カモタ, シュウイチ and ミヤコシ, ヤスキ} }
