Texture study of Ti64xCryNi alloys developed by μ-plasma additive manufacturing process

Abstract

This manuscript presents study of crystallographic texture, phase maps, fraction of β-Ti and α-Ti phases, grain size of α-Ti phase of the Ti64xCryNi alloys developed by μ-plasma additive manufacturing process by adding Cr and/or Ni to aerospace grade Ti64 alloy. Results reveal that addition of Cr and/or Ni refined grains of α-Ti phase and enhanced fraction of β-Ti phase in the developed Ti64xCryNi alloys. Analysis crystallographic texture and phase maps found that grains of the β-Ti and α-Ti phases in the developed alloys are oriented in different directions thus reducing their texture intensity which weakens their texture. It reduced anisotropy thus making mechanical properties uniform in the loading directions. Such texture will be beneficial for those applications where uniform properties are required such as the components subjected to the multi-directional loads in aerospace and automobile applications.
