Abstract:

The purpose of this program is to evaluate the use of plane strain fracture toughness K sub IC as a possible parameter for handbook application. During this report period, a literature survey dealing with the assembly of pertinent K sub IC data has been continued. The experimental effort has involved the determination of plane strain fracture toughness in specimens taken from 8-inch square forged billets of H-11 and 4340 steels. The results indicate that K sub IC did not vary significantly as a function of specimen position within the billet. The room temperature K sub IC parameter for AM 355 steel at aging temperatures between 850F and 1025F was also evaluated. Author
