Description
TARIFNAME Hafif Yapilarin Üretiminde Kullanilmak Üzere Çelik Levha ve Bu Levhanin Üretim Yöntemi Teknik Alan Bulus yüksek bir esneklik katsayisi (E), azaltilmis yogunluk ve yüksek bir dayanim özelliklerini ayni anda sergileyen çelik Ievhalarin ya da yapisal parçalarin üretimi ile Onceki Teknik Yapisal elemanlarin mekanik performanslarinin harici gerilim moduna (örnegin çekme ya da bükülme) ya da elemanlarin (levhalar, çubuklar) geometrisine dayali olarak EX/d (x bir katsayi) seklinde degistigi bilinmektedir. Bu durum yüksek bir esneklik katsayisi ve azaltilmis yogunluk özelliklerini ayni anda sergileyen malzemelere karsi bir ihtiyaci ortaya çikartmaktadir. DESCRIPTION Steel Plate for Use in the Production of Lightweight Structures and Production of This Plate method Technical Area The invention has a high modulus of elasticity (E), reduced density and high strength. with the production of steel sheets or structural parts that simultaneously exhibit Previous Technique The mechanical performance of structural elements depends on the external stress mode (e.g. tensile or or bending) or EX/d (x a coefficient) is known to change. This is a high coefficient of elasticity and revealed a need for materials that simultaneously exhibit reduced density properties. is taking off.
Bu ihtiyaç özellikle araçlarin hafifletilmesi ve güvenlik konularinin sürekli olarak söz konusu olan hususlar oldugu otomotiv endüstrisinde mevcuttur. Bu nedenden dolayi karbürler, nitrürler, oksitler ya da borürler benzeri farkli türlerden seramiklerin parçaciklarinin dahil edilmesi suretiyle çelik parçalarin agirliginin azaltilmasi ve esneklik katsayisinin artirilmasi hedeflenmistir. Gerçekte, bu malzemeler içerisine dahil edildikleri ve 210 GPa mertebesinde esneklik katsayisina sahip olan baz çeliklerin sahip oldugundan daha yüksek olan ve 250 ila 550 GPa araliginda seyreden çok daha yüksek bir esneklik katsayisina sahiptir. Bu sekilde, bir gerilimin etkisi altinda matris ile seramik parçaciklari arasinda bir yük transferi sayesinde bir sertlesme elde edilmektedir. Matrisin tane büyüklügünün seramik parçaciklari ile küçültülmesi de bu sertlesme durumunu artirmaktadir. Bir çelik matris içerisinde yeknesak sekilde dagilmis seramik parçaciklar içeren bu malzemelerin üretilmesi amaciyla toz metalürjisine dayali prosesler bilinmektedir: ilk olarak, kontrollü geometriye sahip seramik tozlar hazirlanir ve bu karisim çelik açisindan seramik parçaciklarin dis kaynakli bir katisina karsilik gelen çelik tozlar ile karistirilmaktadir. Karisimin tamami bir kalip içerisinde sikistirilir ve ardindan bu karisimin sinterlenmesinin gözlemlenecegi bir sicakliga isitilmaktadir. Bu prosesin bir varyantinda, sinterleme asamasi esnasinda seramik parçaciklarin olusmasini saglamak amaciyla metal tozlar karistirilir. Seramik parçacik dagilimina sahip olmayan çelikler ile P424I6527 karsilastirildiginda daha gelismis mekanik özelliklere sahip olmasina ragmen, bu tür bir proses bazi kisitlamalara maruz kalmaktadir: - Metal tozlarinin yüksek spesifik yüzeyi dikkate alindiginda atmosfer ile reaksiyona neden olunmamasi amaciyla bu proses dikkatli gelistirme ve uygulama kosullari gerektirmektedir. This need is especially the case of vehicle mitigation and the constant mention of safety issues. It is available in the automotive industry, where there are issues that are the subject of. For this reason ceramics of different types, such as carbides, nitrides, oxides or borides. weight reduction and flexibility of steel parts by incorporating It is aimed to increase the coefficient. In fact, these materials are included in and base steels with a modulus of elasticity of 210 GPa. much higher than normal and hovering in the range of 250 to 550 GPa has a coefficient of elasticity. In this way, under the action of a stress, the matrix and the ceramic A hardening is achieved by means of a charge transfer between the particles. of the matrix Reducing the grain size with ceramic particles also causes this hardening. is increasing. Uniformly dispersed ceramic particles in a steel matrix Processes based on powder metallurgy to produce these materials containing known: firstly, ceramic powders with controlled geometry are prepared and this steel corresponding to an external welded solid of ceramic particles in terms of a mixture steel mixed with powders. The entire mixture is compressed in a mold and then this It is heated to a temperature at which sintering of the mixture will be observed. This process is a In the variant, to ensure the formation of ceramic particles during the sintering phase. For this purpose, metal powders are mixed. With steels that do not have a ceramic particle distribution P424I6527 Although it has more advanced mechanical properties in comparison, such a The process is subject to some limitations: - Considering the high specific surface of metal powders, it can react with the atmosphere. This process requires careful development and application conditions so as not to cause requires.
-Sikistirma ve Sinterleme islemlerinin gerçeklestirilmesinden sonra dahi döngüsel gerilmeler esnasinda hazirlama sahalari olarak etki etmesi muhtemel kalinti gözeneklerin kalmasi mümkündür. -Cyclic, even after compaction and sintering processes residue likely to act as preparation sites during stresses pores are possible.
- Sinterleme islemi öncesinde tozlarin yüzey kirlenmesi (oksitlerin, karbonun varligi) dikkate alindiginda matris / parçacik arayüzlerinin kimyasal bilesiminin ve dolayisiyla da bunlarin kohezyonunun kontrol edilmesi zordur. - Surface contamination of powders before sintering (presence of oxides, carbon) Considering the chemical composition of matrix/particle interfaces and thus their cohesion is difficult to control.
- Parçaciklarin fazla miktarda ilave edilmesi durumunda ya da belirli büyük parçaciklarin varliginda, uzama özellikleri azalmaktadir. - In case of addition of particles in large quantities or in case of certain large In the presence of particles, the elongation properties are reduced.
- Bu tür bir proses az miktarlarda üretim açisindan uygundur ancak oldukça büyük bir ölçekte otomotiv endüstrisinin ihtiyaçlarini karsilayamamaktadir. - This type of process is suitable for production in small quantities, but requires a fairly large cannot meet the needs of the automotive industry on a large scale.
- Bu tür bir üretim prosesi ile iliskili üretim maliyetleri yüksektir. - The production costs associated with this type of production process are high.
Hafif alasimlar söz konusu oldugunda seramiklerin tozlarinin sivi metal içerisine dis kaynakli olarak ilave edilmesine dayali üretim prosesleri de bilinmektedir. Yine bu prosesler de yukarida bahsi geçen kusurlarin çoguna maruz kalmaktadir. Ama özellikle parçaciklarin homojen dagiliminda zorluklar yasanmaktadir; bu parçaciklar sivi metal içerisinde topaklasma ya da çökelme / y'üzdürme egilimi sergilemektedir. Çeliklerin özelliklerinin artirilmasi amaciyla kullanilabilecek seramikler arasinda asagida belirtilen temel özelliklere sahip olan titanyum diborür (TiBz) özellikle bilinmektedir: Esneklik katsayisi: 565 GPa Yogunluk: 4.52 Ancak, TiBZ parçaciklarin dis kaynakli olarak ilave edilmesine dayali üretim prosesleri de yüksek bir Young modülüne (yüksek esneklik katsayisina (E)) sahip olan ve külçeleme yöntemi kullanilarak üretilebilen yüksek sertlikte bir çelik açiklamaktadir ve özellikle makinenin yapisal bilesenlerini gelistirebilen bir çelik ile ilgilidir. In the case of light alloys, the powders of the ceramics should be embedded in the liquid metal. Production processes based on welded addition are also known. again this processes are also subject to many of the above-mentioned defects. But especially difficulties are experienced in the homogeneous distribution of particles; These particles are liquid metal. It has a tendency to agglomerate or precipitate/float. The following are among the ceramics that can be used to increase the properties of steels. Particularly known is titanium diboride (TiBz), which has the following essential properties: Coefficient of elasticity: 565 GPa Density: 4.52 However, production processes based on the addition of TiBZ particles from external sources are also available. with a high Young's modulus (high modulus of elasticity (E)) and discloses a high hardness steel that can be produced using the relates to a steel that can improve the structural components of the machine.
