Abstract: The basic, remarkable properties lying in the three-workpiece lapping process were previously described by the authors. It was assured there that highly flat surfaces can be obtained predicting ...

Abstract: A single and generalized prediction method of fracture toughness K IC transition curves of pressure vessel steels has been greatly desired by engineers in the petro-chemical and nuclear power ...

Abstract: A new method, designated three-workpiece lapping, is proposed to produce flat surfaces of all the three workpieces prepared through some stages of reciprocation lapping, which is performed by a ...

Abstract: The Cr-Mo steels widely used for pressure vessels have a potential for temper embrittlement. Therefore, embrittlement during long-term service is expected, and it leads to the decrease of the ...

Abstract: A new technique for studying the performance of abrasive tools is described that is not only useful for evaluating the rate of wear of grinding systems but is also capable of yielding difficult ...

Abstract: The procedure for making crack starter weld deposit on drop-weight test (DWT) specimens was altered from two passes to one pass in about 1990. The effects of some parameters of crack starter ...

Abstract: An urgent problem for nuclear power plants is to assess the structural integrity of the reactor pressure vessel under pressurized thermal shock. In order to estimate crack behavior under combined ...
