Assessment of fatigue life of aluminized, coarse-grained MAR247 alloy supported by full-field ESPI measurements

In this paper, fatigue performance of an aluminide layer coated, coarse-grained MAR247 nickel superalloy was monitored by using the full-field Electronic Speckle Pattern Interferometry (ESPI) method in the range of stress amplitude from 350MPa to 650MPa. It was found, that the ESPI method enables precise monitoring of the fatigue behaviour of coated MAR247 specimens since the area of potential failure was accurately indicated within the initial stage of fatigue damage development.

Suitability of DIC and ESPI optical methods for monitoring fatigue damage development in X10CrMoVNb9-1 power engineering steel

The aim of this research was to compare the effectiveness of two different optical measurement techniques (digital image correlation-DIC and electronic speckle pattern interferometry-ESPI) during fatigue damage development monitoring in X10CrMoVNb9-1 (P91) power engineering steel for pipes. The specimens machined from the as-received pipe were subjected to fatigue loadings and monitored simultaneously using DIC and ESPI techniques. It was found that DIC technique, although characterised by lower resolution, was more effective than ESPI. DIC allows to monitor the fatigue behaviour of steel specimens and accurately indicate the area of potential failure even within the initial stage of fatigue damage development.
