摘要:

Magnetic hysteresis loop and magnetic and acoustic Barkhausen noise measurements have been made to characterise strain induceda′-martensite in cold worked AISI type 304 stainless steel. Both magnetic hysteresis and MBN measurements are found to be more sensitive in detection ofa′-martensite as compared to equivalent δ-ferrite and X-ray diffraction measurements. ABN signals could be observed only in the case of 50% cold worked specimens containing high amount ofa′-martensite.

摘要:

Composite materials, particularly E-Glass in the form of “Chop Strand Mat” in a polyester resin arc widely used for the fabrication of pressure vessels and pipework in the Petrochemical Industry. This paper presents details of a potential Non-Destructive Evaluation (NDE) method for the in-service assessment of components manufactured from this type of composite. The method uses ultra-sonic techniques.
