Prof. Dr. Yanling Zhang Prof. Dr. Guoguang Cheng Guest Editors. Zhonghua Zhan Guest Editor Assistant The term "inclusion" is also used in the context of metallurgy and metals processing. During the melt stage of processing particles such as oxides can enter or form in the liquid metal which are subsequently trapped when the melt solidifies. The term is usually used negatively such as when the particle could act as a fatigue crack nucleator or as an area of high stress intensity.
