Abstract

Zirconium is widely used as fuel cladding material in nuclear power reactors. Here, a thermomechanical processing technique has been developed and implemented to improve the mechanical properties of commercially pure Zr-702. In the process the twin density increased to 45 areal%. The twins were identified to be mostly of {101¯2}〈101¯1¯〉 tensile twins or {101¯1}〈101¯2〉 compression twins. The significant increase in hardness was analyzed for its contributing factors and was attributed to the microstructural refinement caused by twin boundaries.
