Paper Title:
High Plastic Ti66Nb13Cu8Ni6.8Al6.2 Composites with In Situ β-Ti Phase Synthesized by Spark Plasma Sintering of Mechanically Alloyed Glassy Powders
  Abstract

High plastic Ti66Nb13Cu8Ni6.8Al6.2 composites with in situ precipitated ductile -Ti phase were firstly synthesized by mechanical alloying and subsequent consolidation by spark plasma sintering with crystallization. Microstructure analysis indicated that all composites contain soft (Cu, Ni)-Ti2 regions and hard -Ti regions, but the two regions have different scale and distribution. The synthesized composites exhibit high fracture strength of 2415 MPa and large plasticity as high as ~31.8%. The large plastic deformability was well explained based on the distinctive microstructure by a developed “hard-soft model”.
