First-principles Study on the Ductility Effect of Zirconium and Its Distinct Behavior from Boron to Restrain Hydrogen-induced Embrittlement in Ni-Ni3Al AlloysYuxi WU and Yuanming WANG 1)Shenyang...,the occupation behavior and the ductility effect of zirconium in a Ni-Ni3AI system were investigated.It is found that zirconium has a stronger segregation tendency to Ni region than to Ni3Al region.The bond......
) in affecting corrosion behavior of zirconium alloys, the Zr-0.85Sn-0.16Nb-0.37Fe-0.18Cr (wt.%) alloy was corroded in super-heated steam at 500 °C and 10.3 MPa under 1×10-6 DO and deaeration..., while those of the (100)m and (110)m are weak. The higher DO content in super-heated steam accelerates the growth of oxide films, thus decreasing the corrosion resistance of zirconium alloys. Key......
