Comparative Studies of the Structure and Residual Stresses Formed During Tantalum Alloying of TiNi Surface Layers by Ion- or Electron-Beam Method

The effect of ion- or electron-beam treatment on the structure and residual stresses formed in the surface layers of the Ta-doped TiNi alloy was revealed. The ion-beam treatment leads to the formation of a thin amorphous surface layer. An ion-beam treated sample does not exhibit residual stresses of...

Description
Summary:The effect of ion- or electron-beam treatment on the structure and residual stresses formed in the surface layers of the Ta-doped TiNi alloy was revealed. The ion-beam treatment leads to the formation of a thin amorphous surface layer. An ion-beam treated sample does not exhibit residual stresses of the 1 st kind, but possesses a low level of residual stresses of the 2 nd kind. Surface alloy synthesis via an electron-beam melting of the Ti 60 Ta 40 (at.%)/TiNi system leads to the formation of the outer crystalline layer, amorphous sublayer, and large residual stresses localized in the heat-affected zone.
