Abstract:
利用光学显微镜、扫描电镜与透射电镜研究了固溶温度和时效处理对热轧态825合金晶粒尺寸和析出相的种类及其形态的影响。结果表明:1020 1 250℃保温30 min固溶,合金的平均晶粒尺寸由45μm增大到330μm;1050 1 080℃和1150 1 200℃分别发生一次晶粒尺寸急剧长大的过程;计算出热轧态825合金的再结晶激活能约为279.14 k J/mol。经700℃×50 h时效与800℃×50 h、900℃×50 h时效,合金中晶界处的主要析出相分别为M 23 C 6 相和M 6 C相;700℃×50 h时效晶界上析出相呈网状、晶粒内部有大量弥散分布的Ti C颗粒;800℃×50 h时效晶界上的析出相呈链状,900℃×50 h时效过程中发生了再结晶。 -
