title = "Effect of shot peening on oxidation resistance of austenitic alloys in SCW conditions",
abstract = "Austenitic stainless steels are attractive candidate materials for the SCWR (Supercritical Water Reactor) concept, with long and successful history in nuclear power generation. Unfortunately their relatively high oxidation rate at estimated peak temperatures of 650 - 850°C (depending on the concept) may severely limit their use as fuel cladding material. However, it has been shown cold working of the exposed surfaces by shot peening can beneficially retard high temperature oxidation of austenitic steels. This report describes the effect of shot peening on the oxidation behavior of three commercially available austenitic steels, 316NG, 347H and 347HFG in SCW at 650°C I 25 MPa for up to 1800 h. Within the tested range, improved oxidation resistance was observed on some samples with certain shot peening parameters.",
