在剖開的鬥齒工件熱節周圍發現氣孔，一起在芯腔的附近壁上也發現存在氣孔。
揉捏鑄件中的氣孔可分為分出性氣孔、侵入性氣孔和反響氣孔，並且在鑄件縮孔、縮鬆的構成過程中大都伴隨著氣體的分出，氣孔與縮孔、縮suo鬆song能neng夠gou說shuo是shi伴ban生sheng的de。假jia如ru合he金jin中zhong含han氣qi量liang過guo高gao，或huo液ye體ti金jin屬shu充chong型xing過guo程cheng中zhong侵qin入ru氣qi體ti過guo多duo，會hui加jia重zhong上shang述shu縮suo孔kong或huo氣qi孔kong的de構gou成cheng。經jing過guo對dui剖pou切qie鬥dou齒chi的de剖pou析xi，能neng夠gou看kan到dao氣qi孔kong散san布bu是shi隨sui機ji的de，並bing且qie孔kong洞dong大da，多duo為wei球qiu形xing和he團tuan球qiu形xing，能neng夠gou判pan定ding此ci氣qi孔kong基ji本ben上shang屬shu於yu侵qin入ru性xing氣qi孔kong。
