Abstract: The metal fracture mechanism in cup ironing process was investigated, taking into account the effect of the galling. Three types of metal cracking were observed, which are distinguishable from ...

Abstract: The centrifugal compressor for a marine use turbocharger with its design pressure ratio of 3.2 was tested with a vaneless diffuser and various vaned diffusers. Vaned diffusers were chosen to ...

Abstract: The object of this paper is to clarity the surface flattening mechanism in the cup ironing process based on the lubricating mechanism. A new experimental apparatus for the ironing process was ...

Abstract: Crack growth behavior of Type 304 stainless steel in a simulated BWR water environment was investigated for the quantitative characterization of subcritical flaw growth in BWR piping systems. ...

Abstract: Flaws due to stress corrosion cracking have frequently been found in Type 304 stainless steel piping of some boiling water reactor (BWR) plants. In this work, in order to quantitatively examine ...

Abstract: Four-point bending and rotating bending fatigue tests were conducted on socket-welded joints made of carbon, stainless, and Cr-Mo steels for clarification of the effects of diameter, welding pass ...

Abstract: The authors conducted fully reversed four-point bending fatigue tests on socket-welded joints 20 to 50 mm in nominal diameter, and rotating bending fatigue tests on socket-welded joints 20 mm ...
