Techniques of Failure Analysis - ASM International

Techniques of Failure Analysis In study of any failure, the analyst must consider a broad spectrum of possibilities or reasons for the occurrence. Often a large number of fac-tors, frequently interrelated, must be understood to determine the cause of the original, or primary, failure. The analyst is in the position of Sherlock Holmes attempting to solve a baffling case. Like the great de ...
