AI Technical Summary
Technical Problem
The prior art is difficult to effectively observe oxidative inclusions in AlV intermediate alloys, especially in the problem of difficulty in distinguishing from holes, resulting in errors in calculating the content of oxide inclusions.
Method used
The metallographic structure is observed by color photography. Through the steps of inlay, grinding, polishing and color photography, the oxidation inclusions are distinguished from holes. The edge color of the oxidation inclusions is red and the edge color of the holes is black.
Benefits of technology
The oxidation inclusions and pores in the AlV intermediate alloy are clearly distinguished, which improves the accuracy of the oxidation inclusion content and avoids calculation errors.

Abstract
The invention discloses a method for observing a metallographic structure of an AlV intermediate alloy oxide inclusion, which comprises the following steps of: 1, mounting, grinding and washing AlV intermediate alloy particles to obtain a metallographic sample; 2, mechanically polishing the metallographic specimen to obtain a mechanically polished metallographic specimen; and 3, placing the metallographic observation plane of the mechanically polished metallographic sample under a metallographic microscope, and observing a metallographic structure by adopting a color photographing mode. According to the method, AlV intermediate alloy particles are made into a mechanical polishing metallographic sample, metallographic structure observation is conducted on a metallographic observation plane in a color photographing mode, it can be seen that the edge color of oxide inclusion phases is red, the edge color of other impurities or hole edges is black, oxide inclusions are clear, and the quality of the oxide inclusions is guaranteed. The problem that impurities and holes are difficult to distinguish in an existing AlV intermediate alloy is effectively solved, and the defect that the content of oxide impurities is wrongly calculated due to improper distinguishing of oxide impurity regions is overcome.
