Study on Copper Precipitation under Electron Irradiation in FeCu Model Alloys by Using Vickers Hardness Measurements
Published online by Cambridge University Press: 01 February 2011
Three kinds of Fe-based model alloys, Fe-0.02wt%Cu, Fe-0.6wt%Cu, and Fe-1.2wt%Cu were irradiated with 2MeV electrons at 250°C. After the irradiation, the hardness was measured by using a micro Vickers hardness tester at room temperature. It was found that the hardness change by electron irradiation is proportional to the product of the copper concentration and the square root of electron fluence. The result is discussed in terms of the dispersion strengthening by Cu precipitates.
