Abstract




Dört farklı
kompozisyonlu Cu-esaslı şekil hatırlama alaşımlarının yüksek sıcaklık
oksitlenme özellikleri hava atmosferi altında 150 °C - 900 °C
sıcaklık aralıklarında thermogravimetrik
analiz (TGA) ile incelendi. Isıtma hızı ve alaşımlama elementlerinin
çeşidine bağlı olarak toz numuneler incelendi ve oxsitlenme hızları TGA ile
belirlendi. Sonuçlar işaret edilen alaşımlarda artan Al içeriği ve artan ısıtma
hızına bağlı olarak, oksidasyon hızının arttığını gösterdi.

Abstract




High temperature
oxidation behaviours of with four different composition Cu-based shape memory
alloys have been investigated by thermogravimetric
analysis (TGA) in the temperature range of 150 °C - 900 °C under
air atmosphere. Depending on the heating rate and the alloying elements types,
the weight gains of the powdered samples were investigated and the oxidation
rates have been determined by TGA. The results indicate that increasing of Al
content in the alloys and increasing the heating rate, increase the rate of
oxidation.
