| 1 | Optimization of N18 Zirconium Alloy for Fuel Cladding of Water Reactors显示文摘In order to optimize the microstructure and composition of N18 zirconium alloy(Zr-1Sn-0.35Nb-0.35Fe-0.1Cr,in mass fraction,%),which was developed in China in 1990s,the effect of microstructure and composition variation on the corrosion resistance of the N18 alloy has been investigated.The autoclave corrosion tests were carried out in super heated steam at 400 ℃/10.3 MPa,in deionized water or lithiated water with 0.01 mol/L LiOH at 360 ℃/18.6 MPa.The exposure time lasted for 300-550 days according to the test temperature.The results show that the microstructure with a fine and uniform distribution of second phase particles(SPPs),and the decrease of Sn content from 1%(in mass fraction,the same as follows) to 0.8% are of benefit to improving the corrosion resistance;It is detrimental to the corrosion resistance if no Cr addition.The addition of Nb content with upper limit(0.35%) is beneficial to improving the corrosion resistance.The addition of Cu less than 0.1% shows no remarkable influence upon the corrosion resistance for N18 alloy.Comparing the corrosion resistance of the optimized N18 with other commercial zirconium alloys,such as Zircaloy-4,ZIRLO,E635 and E110,the former shows superior corrosion resistance in all autoclave testing conditions mentioned above.Although the data of the corrosion resistance as fuel cladding for high burn-up has not been obtained yet,it is believed that the optimized N18 alloy is promising for the candidate of fuel cladding materials as high burn-up fuel assemblies.Based on the theory that the microstructural evolution of oxide layer during corrosion process will affect the corrosion resistance of zirconium alloys,the improvement of corrosion resistance of the N18 alloy by obtaining the microstructure with nano-size and uniform distribution of SPPs,and by decreasing the content of Sn and maintaining the content of Cr is discussed. | B.X.

| 3 | EFFECT OF Si ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF THE Al-4.5%Cu ALLOYS显示文摘The effect of Si on the microstructure and mechanical properties of binary Al-4.5%Cu alloy has been investigated. The results show that the addition of Si does not have any effect on alloy strength; however, it decreases the ductility of the as-cast Al-4.5%Cu alloy. It is obvious that after T4 heat treatment, the microstructure and mechanical properties of Al-4.5%Cu-Si alloys are improved, especially for the alloy with an Si addition of 2%. | N. Han, X.F.

| 11 | OUT-OF-PILE CORROSION RESISTANCE OF NEW ZIRCONIUM ALLOYS IN 500 ℃/10 3MPa STEAM显示文摘he out of pile corrosion resistance of new Zirconium alloys in 500℃/10 3MPa steam has been investigated and the effect of alloying elements, Sn,Nb,Fe,Cr on the property has been analyzed. The results show that the new alloys have better corrosion resistance than Zircaloy 4. That no nodular corrosion is found during test cycles shows the nodular corrosion resistance can be dramatically improved by addition of alloying elements Nb. The Fe/Cr ratio should be properly controlled if there is Cr addition in the alloys when developing new alloys. | Z.K. Li 1,2) , L.Zhou 1,2) , J.Z. Liu 1) , P.Z. Li 1) and W.J.
