An experiment of post-irradiated annealing for ion-irradiated stainless steel model alloy was performed to investigate the mechanical changes and microstructural changes by using nano-indenter, TEM observation and 3DAP measurement. The thermal stability and barrier factor strength of solute atom clusters formed by ion irradiation were evaluated....

In order to investigate that the hardening with δ hydrides generation in Zr was influenced by the relationship between the slip plane of dislocation and the habit plane of δ hydride, the EBSD analysis, the nano-indentation hardness test and the in-situ TEM observation during tensile test were performed. In the case when the δ hydrides of crystal orientation relationship (habit plane) of (0001)α plane//{111}δ plane and <2-1-10>α direction//<110>δ direction were precipitated in the Zr sample, the hardening of...

In-situ TEM observation during tensile deformation test for an ion-irradiated SUS316L steel was performed to investigate a dislocation interaction with irradiation-induced defect clusters. Hardening contribution of irradiation-induced defect clusters such as solute atom clusters was estimated with experimental methodology using dislocation pinning behavior during tensile deformation. The utilization method of the in-situ TEM observation technique for hardening evaluation for irradiated materials was also di...

An irradiation hardening behavior in a SUS316 steel was investigated from the ultra-micro hardness test after hydrogen ion irradiation as parameters of irradiation dose and indentation depth systematically. Based on the crystal orientation of the sample surface specified using EBSD, comparative evaluation of ultra-micro hardness in the same crystal orientation relationship was performed. Cross-sectional TEM observation of ion-irradiated microstructure under the indentation after deformation was performed to...

The phase decomposition behaviour of an experimental High-chromium Ferritic steel containing 40 wt.% chromium (Fe-40Cr) irradiated with 8 MeV electrons was studied by positron annihilation lifetime (PAL) measurements and coincidence Doppler broadening (CDB) of positron annihilation radiation measurements. Electron irradiation at 100 and at 475 ?C were performed on the specimens to nominally 0.03 to 0.3X10-3 dpa. The rapid increase of W-parameter obtained from the specimen irradiated at 100 ?C is most like...
