【摘要】 设计加工了专用夹具和引伸计,在国产RD2-3型蠕变试验机上成功地进行了一整段φ10mm× 0.7mmZr-4合金管的高温蠕变试验,并用比长仪法和引伸计法测得的数据进行分析比较。分别推断给定应力条件下的残余应变,取得了和实际相一致的结果。更多还原

【Abstract】 Creep test of a short complete section of F10mm×0.7mm Zr-4 alloy pipe was performed on a domestic RD2-3 type creep test machine with specially designed grip and extensometer. The results was compared with that obtained by comparator method. Residual strain at given stress level was regression analysed, and was in good agreement with experimental result.更多还原
