“…Döküm denemeleri yaparak simülasyon sonuçları ile kıyaslamalı çalışmalarında Lohmüller ve ark. [43], AZ91D alaşımını Thixomolding® (Tiksödöküm) yöntemi ile üretmişler ve gözenekliliğin sıcaklıkla değişimini incelemişlerdir. Yaptıkları denemeler sonucunda 580-605°C arasındaki sıcaklıklarda katı faz içeriği %30 dan neredeyse sıfıra düştüğünde, yüksek katı faz içeriğinin ince duvarlı parçalarda gözenekliliği azalttığı ortaya çıkmıştır.…”

ÖZETMagnezyum alaşımlarının havacılık, uzay ve otomotiv endüstrisinde yapısal malzeme olarak kullanımı gün geçtikçe artmaktadır. Henüz yaygın kullanımda olmaması ve üretiminin pahalı olması nedeniyle üreticilerin sayısı demir ve çelik üreticilerine göre çok daha azdır. Bu durum magnezyum alaşımlarının pahalı olmasının temel sebeplerinden biridir. Bu çalışmada, magnezyum ve alaşımlarının imalat yöntemleri, şekillendirilebilirlik, korozyon direnci, çevreye olan etkileri ve mevcut kullanım alanları incelenmiştir.Anahtar Kelimeler: Magnezyum, magnezyum alaşımları, hafif malzemeler. INVESTIGATION OF MAGNESIUM ALLOYS AND THEIR APPLICATIONS ABSTRACTThe use of magnesium alloys in aerospace, space, and automotive industry as structural materials has gradually been increased. Magnesium alloys producers are much less than the iron and steel producers in number due to the alloys are still not widely used and their production cost are high. This is one of main reasons that the prices of the alloys are expensive. In this study, the manufacturing techniques, formability, corrosion resistance, environmental effects of magnesium and its alloys and applications were investigated.

“…Thixomolding is a recent semisolid technology mainly used for production of near net shaped magnesium components. [3,4] Distinct from conventional casting process, the thixotropic behavior of alloys in the semisolid state is exploited. In many semisolid processes it is necessary to produce a starting billet by stirring the material during solidification in order to obtain the proper thixotropic microstructure.…”

Thermodynamic Simulation of Phase Formation During Blending of Mg‐Alloys by Thixomolding

2007

View full text Add to dashboard Cite

Thixomolding, as a semisolid processing approach, offers a unique opportunity to produce new Mg‐alloys by mixing different feedstock chips at room temperature. This way of blending or mixing two or more commercially available standard Mg alloys will produce a new alloy with different melting range, solidification path, phase distribution and metallurgical and mechanical properties. This paper demonstrates the applicability of thermodynamic modeling to generate detailed information about phase formation in thixomolding process. For this purpose the process is pictured by appropriate thermodynamic calculations using a multicomponent Mg alloy database.

“…The work presented here is an extension to semi-solid metal injection molding. At this point there are very few published simulation results for the injection molding of semi-solid magnesium [10][11][12]. Kim et al [10] used the commercial software MAGMA to make 3D computations.…”
