Abstract

Sekil bellekli butun malzemeler deJormasyona ( egme, ktvtrma,

vb) ugrauldiktan sonra tsttma sonucu eski seklini hattrlayarak

deformasyondan onceki haline geri doner. Bunun sebebi sekil bellekli

alastmlartn martenzitik yaptya sahip olmastdtr; Martenzitik durumda

deJormasyona ugratilan sekil bellekli alasim tsuma sonucu yiiksek sicakltk

fazt ostenite donuserek deJormasyondan onceki haline geri doner.

Keywords

Martenzit , Sekil Bellek Etkisi , Termoelastik Martenzit , Elektron - Atom Oranı
