Microscopic observation, and electrochemical and immersion tests highlighted the significant influence of annealing temperature on corrosion rates. Alloy wires annealed at 150 °C demonstrated superior corrosion resistance, which is attributed to small and uniform grains, low stress, and a well-distributed nano-second phase.

The results demonstrate that, although the PH-Mi process consumes higher amounts of energy, electricity, and chemicals compared to the PH-M process, it is more environmentally friendly and economically efficient (i.e., net profit increased by 34.12%).
