Standard Practice for Production and Evaluation of Field Metallographic Replicas

Importancia y uso:

4.1 Replication is a nondestructive sampling procedure that records and preserves the topography of a metallographically prepared surface as a negative relief on a plastic film (replica). The replica permits the examination and analysis of the metallographically prepared surface on the LM or SEM.

4.2 Enhancement procedures for improving replica contrast for microscopic examination are utilized and sometimes necessary (see 8.1).

Note 1: It is recommended that the purchaser of a field replication service specify that each replicator demonstrate proficiency by providing field prepared replica metallography and direct LM and SEM comparison to laboratory prepared samples of an identical material by grade and service exposure.
