Abstract
Metal köpükleri yapısının %75 ile %90‟ı
gözeneklerden oluşmuş, rijit saf metal ya da alaşımlardır. Isıl davranışları,
enerji absorbe etme yetenekleri, düşük yoğunlukları, yüksek kesme ve kırılma
mukavemetleri ve düşük ağırlıklarından dolayı tercih edilen yeni bir malzeme
gurubudur.[1]. Köpük metallerin “açık hücreli” ve “kapalı hücreli” olmak üzere
iki çeşidi vardır. Metal içerisindeki
gözenekler birbiriyle bağıntılı bir halde bulunuyorsa bu yapıya “açık hücreli
köpük metal” adı verilmektedir. “Kapalı hücreli köpük metaller” de ise
hücrelerin her birinin içerisinde gaz hapsedilmiştir ve birbirinden yalıtılmış
bir halde bulunmaktadır.[2] .Metal köpükleri elde etmek için çok çeşitli
yöntemler kullanılmaktadır. Bu çalışmada nispeten ucuz ve kolay olan tuz kullanılarak
açık hücreli metal köpük üretimi yöntemi ele alınmıştır.

Abstract
Between 75% and 90% of
metal foams structure is solid pure metal or alloys which was made of pores. It
is a new group of material, because of its thermal behaviours, energy absorbing
abilities, low densities, high shear and fracture strengths and low weights.
There are two kinds of foam metals; open cell foam metals and close cell foam
metals .If the pores in the metal structure are located relative to each other,
the structure is called ‘open- cell foam metal’. However,in the structure of
close cell foam metals, gas is locked in
each of the cells and cells occur isolated from each other. Many different methods are used to obtain metal foams. In this study, by using salt,
production method of open cell metal foam which is relatively cheap and easy to
get is considered
