    Atomizasyon yöntemi ile metal tozları üretimi ve endüstriyel uygulamaları
    (Uludağ Üniversitesi, 1984) Yerebakan, Metin; Uludağ Üniversitesi/Mühendislik Fakültesi/Makina Mühendisliği Bölümü.
    Processing of powder materials begins with consideration of the powder properties and caracte­ristics such as size, shape, composition and structure. These powder features affects the response of subsequent compaction. sintering and densitication processes. Considerable effort is directed toward improved understanding of powder production-method called "atomisation" is reviewed, The mostflexible process in high tonnage production is atomisation since it provides the capability to produce gich quality alloy powders and affords greatest control over powder properties.

    Effecfs of gravity on interdendritic fluid flow in large remelted ingots
    (Uludağ Üniversitesi, 1984) Yerebakan, Metin; Uludağ Üniversitesi/Mühendislik Fakültesi/ Makine Mühendiliği Bölümü.
    This paper presents analytic calculations of the interdendritic fluid-flow in mush zones whose width is small compared to their length, a situation which is caracteristic of large remelted ingots. The flow is found to consist of two main components. The first one is normal to the isotherms which feeds solidifi­cation shrinkage and the second one is parallel to the isotherms which is produced by gravity acting on desity differences in the interdendritic liquid. If the isotherms are not exactly parallel, then the gravity induced flow parallel to the isotherms induces a component normal to it. This companent may cause the freckles that occur in remelted ingots when melting conditions are changed.

    Kristalin grafit ve dökme demirlerde grafit morfolojisi
    (Uludağ Üniversitesi, 1984) Yerebakan, Metin; Uludağ Üniversitesi/Mühendislik Fakültesi/Makina Mühendisliği Bölümü.
    Bu yazıda grafitin kristalize oluşuna ilişkin çeşitli teknikler ile kristal grafitin dökme demirlerdeki morfolojisi incelemektedir. Grafit kristallerinin elde edilmesi ile grafıtin modifikasyonları üzerinde durula ­ rak, daha yüksek mukavemetli dökmedemirlerin üretilmesinde morfolojik olarak grafitin rolü izah edilmek ­ tedir.
