摘要：
Specimen reconstitution techniques offer the possibility to obtain fracture toughness measurements when only small amounts of material are available. In order to obtain extra information from Charpy specimens, an electron-beam weld reconstitution method is established to obtain Compact Tension specimens from the broken halves of Charpy specimens. The validity of the fracture toughness characterisation is analysed by comparing J(R)-resistance curves of specimens with insert and those of normalised specimens without insert.
