C編}, month = {Jul}, note = {Experiments of diffusion bonding were carried out at elevated temperatures for 30 min in a vacuum. Strengths of as-bonded specimens (without further machining) were measured by 4 points bend test. Specimens to be bonded have asperities in wedge shape on the upper ends. The asperity angles were 100°, 120°, 140° and 160°. The surfaces to be bonded were brought into contact with the redges on the specimen perpendicular to those on another specimen. The bonding strengths of the asperity angles of 100°and 160°were higher than those of asperity angles of 120° and 140°. The bonded areas were almost equal at from 100° to 140° and the largest boded area was observed at 160°. The bonding strength became low when the bonding pressure was high at the end of the bonding process. The bonding strength of 35% prestrained specimens were almost equal to those of not prestrained specimens. The bonded areas of 35% prestrained specimens were, however, smaller than those of not prestrained specimens.}, pages = {1814--1819}, title = {拡散接合の接合強度と接合面積に及ぼすSUS304突起頂角の影響}, volume = {55}, year = {1989} }
