The Effect of the Initial State on the Structure Evolution of Hafnium Bronze under Annealing

In this paper, we study the structure evolution of hafnium bronze undrer annealing after hardening and severe plastic deformation by two methods: dynamic channel-angular pressing (DCAP) and high-pressure torsion (HPT). Severe plastic deformation of hardened bronze is shown to lead to significant har...

Description
Summary:In this paper, we study the structure evolution of hafnium bronze undrer annealing after hardening and severe plastic deformation by two methods: dynamic channel-angular pressing (DCAP) and high-pressure torsion (HPT). Severe plastic deformation of hardened bronze is shown to lead to significant hardening. Under the annealing of bronze, additional hardening occurs due to the precipitation of Cu 5 Hf particles. The bronze structure after severe plastic deformation has a high thermal stability; the maximum hardness is achieved upon annealing at 400°C after DCAP and 300–400°C after HPT.
