Embrittlement of Reactor Pressure Vessel Steel A508: A Look on Mesoscopic Levels


Embrittlement of Reactor Pressure Vessel Steel A508: A Look on Mesoscopic Levels

Borodin, V. A.; Böhmert, J.

We present the results of fractographic study of standard V-notch Charpy specimens of US steel A508, tested at different temperatures ranging from the lower to upper shelf. The same fracture cross sections were studied at progressively increasing magnifications from x10 up to x20000, using both stereo optical microscopy and scanning electron microscopy. The results demonstrate that test conditions at mesoscopic and macroscopic length scale levels are important factors influencing the crack propagation.
