REAVEALING, IDENTIFYING AND ASSESING FLAW DEVELOPMENT IN HIGH CHROMIUM STEELS BY QUANTITATIVE ACOUSTIC EMISSION NON-DESTRUCTIVE INSPECTION METHOD

摘要：

The research has shown that the appearance, development and interaction flaws in high chromium steel is accompanied by continuous and burst AE, whether under stable or increasing single or cyclic loading. The peculiarities of the AE data make it possible to reveal, recognize, and quantitatively assess flaws with low and high stress intensity. So, Quantitative Acoustic Emission Nondestructive Inspection Technology created by authors was used to distinguish between flaw-free specimens, welded specimens with a limited number of industrial flaws, and those that had undergone significant embrittlement and contained fatigue cracks and/or micro- cracks.
