Abstract
On many occasions, problems which superficially look like a simple “it bust” type of failure, have been shown to be much more significant when micro-examination is applied to the parts involved. It is, of course, important that the people who are in first hand contact with such failures should be sufficiently curious, want technical verification, or be required formally to make the evidence available for diagnosis. In this paper several case histories of failures in boilers and related components in which metallography played an unsuspected level of significance will be presented. Also included are a couple of examples which demonstrate the value of visible and macro evidence in the diagnosis.
