Nb元素含量对U-Nb合金显微组织和比热容的影响
Effect of Nb content on the microstructure and the specific heat capacity of U-Nb alloys
摘要
Abstract
U-Nb alloy had good corrosion resistance,structural stability and processability,it was an important structural material in the nuclear field.Quenched U-Nb alloys with different Nb element contents were prepared,and their microstructure and specific heat capacity were studied.The results show that there was a large amount of coarse needle like martensite in the quenched U-2Nb alloy.As the content of Nb element increased,martensite gradually disappearred,and U-Nb alloy formed equiaxed crystal structure.With the increase of Nb element content and temperature,the specific heat capacity of U-Nb alloy gradually increased.When the temperature exceeded 650℃,the U-Nb alloy underwent phase transformation and the specific heat capacity significantly decreased.关键词
