使用定量金相显微镜作定量测量时,由于选择的设备参数不同以及试样的制备方法不同,其测量结果也往往不同,有时差别很大.为了使测量参数准确和有可比性,有必要统一和标明参数的测量条件.此外,对试样作重复测量或试样重复制备后再测量,其测量结果也不相同.为此我们对EPIQUANT定量金相显微镜各设备参数、试样制备方法对测量结果的影响以及试样重复测量时数据的稳定性进行了研究. 一定量金相显微镜设备参数对测量结果的影响用变形铝合金试样研究了放大倍数、测量场大小、测量速度快慢及测量光阑大小对测量结果的影响.各种变形铝合金铸造组织大致分两类,一类是网状组织,如LD2合金铸锭,其第二相呈网状分布,见图1;另
Quantitative metallographic microscope for quantitative measurement, due to the choice of equipment parameters and sample preparation methods are different, the measurement results are often different, sometimes very different.In order to make the measurement parameters accurate and comparable, it is necessary to unify and Indicate the parameters of the measurement conditions.In addition, the sample for repeated measurements or re-measurement of the sample after the remeasurement, the measurement results are not the same.To this we EPIQUANT quantitative metallographic microscope equipment parameters, sample preparation method of the measurement results And the stability of the data when repeated measurement of the sample was studied.A certain amount of metallographic microscope equipment parameters on the measurement results with the deformation of the aluminum alloy specimen magnification, measuring the size of the field, the measurement speed and measurement aperture The size of the measurement results.A variety of deformed aluminum alloy castings roughly divided into two categories, one is the reticular organization, such as LD2 alloy ingot, the second phase was reticular distribution, shown in Figure 1; the other
