本文叙述了铝硅合金和铁碳合金中堆积边三维观测的一些注意事项。本研究主要明确了二次相晶粒（Si和Fe3C）、晶粒直径和其他合金晶粒（Al2Cu、Mg2Si和A13Ni等）对堆焊边外观和内部组织的影响。为此，利用扫描电子显微镜（SEM）和x射线衍射仪对堆积边缘进行了充分的研究。得到的主要结果如下。(1)建筑边缘是由树形单元元素的内聚形成的。(2)落在切屑背面和加工表面的碎片不像王牌被推下一样落在切割宽度上，而是随机地从内置边缘的树形单元分裂到切屑和加工表面。分裂发生在建筑边缘的尖端附近。(3)二次相晶粒（Si、Fe3C）和其他合金晶粒（Al2Cu、Al3Ni、Mg2Si）在外表面和内积边组织中被粉碎。
This paper describes some considerations at the three dimensional observation of a built-up-edge in Al-Si and Fe-C alloys. This study mainly makes clear up the effects of the secondary phase grains (Si and Fe3C), the diameter of the crystal grains and other alloy grains (Al2Cu, Mg2Si and A13Ni, etc.) on the external appearance and internal structure of the built-up-edge. For that purpose, the built-up-edge is sufficiently investigated by use of the scanning electron microscope (SEM) and X-ray diffraction apparatus. Main results obtained are as follows.(1) The built-up-edge is formed by the cohesion of, the unit elements of the arborization shape.(2) The fallen fragments into the back face of a chip and machined surface do not lie over the cutting width as if trump cards were pushed and downed, but split from the arborization unit of the built-up-edge at random to the chip and machined surface. And the split occurs near the tip of the built-up-edge.(3) The secondary phase grains (Si, Fe3C) and other alloy grains (Al2Cu, Al3Ni and Mg2Si) are crushed finely in the external surface as well as the internal structre of the built-up-edge.
