超塑合金中含有0.04～0.05%镁,可使合金组织致密,提高强度。因此要求分析方法测定结果精密度高。本文根据生产要求,试验采用原子吸收分析的高精密度测量技术,并拟定了相应的分析方法。高精度测量法这种测量方法的要点是配制相近于试样含量的两个标准试样(一个高于,另一个低于试样含量),然后计算得出试样含量,其步骤如下:(1)制备一套标准系列(Mg%=0.01～0.05%,间隔0.005%),按常规方法测定试样,求得试样大致含量;(2)选择标准系列中两点,其浓度
Superplastic alloys contain 0.04 to 0.05% of magnesium, the alloy can make dense, improve strength. Therefore, the analytical method requires high precision results. In this paper, according to the production requirements, the test using atomic absorption analysis of high-precision measurement techniques, and developed the corresponding analysis. High-precision measurement method The main point of this measurement method is to prepare two standard samples (one above and one below the sample content) close to the sample content, and then calculate the sample content, the steps are as follows: ( 1) Prepare a set of standard series (Mg% = 0.01-0.05%, interval 0.005%), and measure the sample according to the conventional method to determine the approximate content of the sample; (2) Select two points in the standard series,
