在Ｔ＝１１０～１９５℃及ε＝０．４×１０（－３）～２．４７×１０（－３）Ｓ（－１）时对Ｚｎ－１．８％Ａｌ合金超塑性ｍ－δ曲线进行了测定，属ｍＬ＝ｍｍｉｎ型。可分为基本形式、上升式及下降式三种形式。应用ＣＬ（刘勤）方程式对Ｃ值进行了计算，获得了全部有关特征参数，包括（δ０＝０），δＬ，δＦ；ｍ０（≠０），ｍＬ，ｍＦ；（Ｃ０＝ｋ０／ｋ０＝１），ＣＬ（＝ｋＬ／ｋ０）及ＣＦ（＝ｋＦ／ｋ０）的全部或一部分，由曲线的形式决定。测到的总延伸率δＦ＝１９０／～４１０％．各自由每根ｍ－δ曲线的其余特征参数的动静态或直间接效应的综合结果所决定。进一步否定了当前超塑性领域内存在的错误观点。并对有关微观变化进行了初步研究。
The superplastic m-δ curves of Zn-1.8% Al alloy at T = 110 ~ 195 ℃ and ε = 0.4 × 10 -3 ~ 2.47 × 10 -3 were studied. Measured, is a mL = mmin type. Can be divided into basic forms, ascending and descending three forms. (C0 = k0 / k0 = 1) is calculated by using CL (Liu Qin) equation to calculate all the relevant characteristic parameters, including (δ0 = 0), δL, δF; m0 ), CL (= kL / k0) and CF (= kF / k0) all or part of the curve determined by the form. The total elongation measured, δF = 190 / ~ 410%. The individual results are determined by the combined result of the dynamic and static or direct effects of the remaining characteristic parameters of each m-δ curve. Further denying the current superplastic areas of error exist. And a preliminary study of the relevant micro-changes.
