CuZn40Pb2’nin Elektriksel İletkenliği Üzerine Aşırı Plastik Deformasyonun Etkisi

Bu çalışmada, CuZn40Pb2 pirinç malzemesi hem ticari nitelikte hem de eşit kanal açısal presleme (EKAP) işlem metodu ile tek pas kullanılarak aşırı plastik deformasyonu oluşturularak elektriksel özellik üzerine mikroyapı ve mekanik özelliklerin etkisi incelenmiştir. Özellikle Cu bazlı malzemelerin elektriksel ve korozyon özelliklerinin iyi olduğu bilinmesine karşın tane boyutlarında elde edilebilecek küçülmelerin mekanik ve fiziksel özelliklerini nasıl etkilemiş olabileceği çalışmanın temelini oluşturmaktadır. Bilindiği üzere ticari özelliklerde pirinç alaşımları endüstriyel anlamda gemi sanayiinde, otomotiv sanayiinde ve diğer birçok endüstriyel alanda uygulama içerinde kullanılmaktadırlar. Bu kapsamda yapılan çalışma ile EKAP tekniği kullanılarak CuZn40Pb2 malzemesi tane boyutları ufaltılmış, sertlik özelliklerinde %34 artış ve elektriksel özelliklerinde ise %3 azalma göstermiştir.

The Effect of Severe Plastic Deformation on the Electrical Conductivity of CuZn40Pb2

In this study, the effects of microstructure and mechanical properties on electrical properties of CuZn40Pb2 brass material were investigated by using both a commercial quality and an equal channel angular pressing (ECAP) process. Especially, although it is not known that the electrical and corrosion properties of Cu-based materials are good, it is the basis of studying how mechanical and physical properties of the size reductions may be affected. As is known, commercially available brass alloys are used industrially in the shipbuilding industry, the automotive industry and many other industrial applications. In this study, the grain size of CuZn40Pb2 material decreased and the hardness properties increased at 34% and electrical properties decreased at 3% with ECAP technique.
