用扫描电镜观察分析了各种实验室模拟火灾条件下铝导线及其熔珠熔痕的显微组织结构特征,并和火灾现场取样的组织结构相比较,结果表明:当火灾现场取样结果显微结构出现树枝晶和柱状晶时,能基本判定火灾原因为导线一次短路所致;但当取样结果显微结构仅主要出现大块再结晶体时,则需根据现场情况具体分析。
2) melting trace
熔痕
1.

模拟火灾现场条件,分别制备铝导线火灾前短路和火灾中短路痕迹,利用扫描电子显微镜对铝导线熔痕气孔的微观形貌进行观察和分析,发现铝导线的火灾前短路气孔内的晶体形态为胞状,且晶粒之间存在微孔和间隙,气孔内散落这大量的微晶,火灾中短路熔痕气孔内的晶体形态为柱状,晶粒之间连接紧密,但气孔内可能存在集中缩孔,气孔内可能有杂质痕迹存在,二者具有明显的差别。
3) melted bead
