摘要 用示差式石英膨胀仪在室温至800℃范围内测量了Zr、Zr-4合金、N18新锆合金、N36新锆合金的热膨胀行为,给出了测量结果的经验公式,并对这些材料的热膨胀行为进行了比较。测量结果表明,Zr-4合金、N18新锆合金、N36新锆合金棒材试样的热膨胀基本相同,金属Zr、Zr-4合金和新锆合金板材试样的热膨胀都存在各向异性。 In this paper, the expansion behavior of rod and plate of Zr, Zr-4 and new zirconium alloys was studied from room temperature to 800℃ by using quartz dilatometer. The results showed that there had little difference among N18, N36 and Zr-4 alloys. The relationship between linear thermal expansion and microstructure of N18 plate was studied and from the results it could be concluded that there lied anisotropy for the cold-rolling of Zr, Zr-4 and new zirconium alloys
