Microhardness and microstructure evolution of ultra-fine grained Ti-15Mo and TIMETAL LCB alloys prepared by high pressure torsion
Result description
The evolution of microhardness, microstructure and elastic constants of two metastable β-Ti alloys with increasing strain imposed by high pressure torsion was investigated. Fragmentation of the microstructure was observed by scanning electron microscopy. Microhardness significantly increases with increasing strain and was fitted using Hollomon and Voce laws. The measurement of elastic constants using resonant ultrasound spectroscopy showed that the deformation by high pressure torsion increases the Young's modulus as compared to solution treated material. On the other hand, further straining causes subsequent decrease of the Young's modulus.
