引言硼化钛可能导致各种铝箔缺陷,但迄今为止尚未有关于无缺陷铝箔中TiB_2分布状况的描述。为了确定铝箔中包括TiB_2在内的微量夹杂物的分布情况,必须对大量的表面进行研究。NIAR为此提供了可能,并为进一步对低倍缺陷进行有目的的试验、分析创造了条件。这种方法比制备薄的箔材金相磨片方便,通过 Introduction Titanium boride can lead to various aluminum foil defects, but so far there is no description of the distribution of TiB2 in non-defective aluminum foil. In order to determine the distribution of trace inclusions in the aluminum foil, including TiB 2, a large number of surfaces must be studied. NIAR offers the possibility for this, and has created the conditions for carrying out purposeful experiments and analysis on low magnification defects. This method is easier to pass than preparing thin foil metallographic rubs
