一、前言铝制品的许多性能与其中的杂质密切相关.典型的例子是,金属印刷铝板(PS板——译者注)的质量由于存在大夹杂物而降低,许多铝合金的塑性受富铁金属间相的大小及其分布的极大影响.现在,铝工业通过对熔体进行净化,对杂质进行分析,可在很大程度上对其产品质量进行控制.关于杂质的取样与分析主要有两个问题:一是夹杂物在熔体中的分布通常不均匀,二是其浓度非
I. INTRODUCTION Many properties of aluminum products are closely related to the impurities in them. A typical example is the decrease in the mass of metal-coated aluminum sheets due to the presence of large inclusions, The size of the intermetallic phase and its distribution have a tremendous impact now, the aluminum industry through the purification of the melt, the analysis of impurities, to a large extent, the quality of their products to control the sampling and analysis of impurities are Two problems: First, inclusions in the melt distribution is usually uneven, and second, the concentration of non-
