Material Qualification can expose improper heat treatment of critical components as one of the primary factors that contribute to failures. One of the problems associated with field failures is the fact that the test coupon used to certify the properties of the components may be processed at different times than the part(s) it qualifies. The specified mechanical properties may not necessarily be required or achieved through the entire section thickness of the production part(s). Material Qualification procedures are intended to provide the manufacturer and end user with a means of ensuring that the QTC is more representative of the mechanical properties in a large cross section component than can be expected with a standard specification. Furthermore, these procedures are intended to provide to optimize the heat treatment and heat treatment response of large cross section components, thereby insuring that the component has the required mechanical properties at the depth below the surface established by the manufacture at all critical locations.
