The work demonstrated TWI’s strong on-site metallographic capabilities, and its ability to take replicas from a wide variety of surfaces.
While the information provided is not as extensive as that yielded by sectioning, namely a destructive technique, the components in question were not removed or damaged and continued to be used after metallographic replication.
Combining metallographic replication with other non-destructive techniques, such as dye penetration or ultrasonic testing, yields a considerable amount of information in a matter of hours.
TWI also offers a training course in basic on-site metallography. To learn more please email contactus@twi.co.uk
