ABSTRACT:
Fabrication of the test structure is functionally illustrated in FIG. 9. More specifically, the first step in the process is to machine the cavity 40 in the third body of austenitic material 42, as functionally illustrated at reference numeral 80. After the cavity 40 has been machined, the fault sample 34 is installed into the cavity by heating the third body of austenitic material 42 and cooling the fault sample 34. This process is functionally illustrated at reference numeral 82. After installation of the fault sample 34, the interface is welded to seal the junction and the combined structure HIP bonded, as functionally illustrated at Reference Numerals, 84 and 86. After bonding the test structure is machined into the desired configuration, as functionally illustrated at Reference Numeral 88.
