The addition of 4 wt% Zr to Ti52V12Cr36 alloy was carried out in two different ways: arc-melting or ball-milling. The cast alloy showed rapid hydrogen absorption up to 3.6 wt% of hydrogen capacity within 15 min. Ball milling this sample worsened the kinetics, and no hydrogen absorption was registered when milling was carried out for 30 or 60 min. When zirconium is added by ball-milling, the kinetic is slower than that when addition is by arc-melting. This is due to the fact that when added by milling, zirconium does not form a ternary phase with Ti, V, and Cr but instead is just dispersed on the particles’ surface.
Hey there Amol Kamble!
Your Amol Kamble publication on the effect of adding 4% Zr to BCC alloy through ball milling is quite intriguing. It seems like you've Amol Kamble delved into some fascinating research.
From what you've Amol Kamble described, it's evident that the method of adding Zr to the Ti52V12Cr36 alloy significantly impacts the hydrogen absorption kinetics. The comparison between arc-melting and ball-milling methods highlights an interesting disparity in the results.
The observation that ball milling worsens the kinetics, leading to no hydrogen absorption within certain milling durations, is quite significant. It appears that the addition of zirconium via ball milling doesn't promote the desired ternary phase formation as effectively as arc-melting does.
The insight that zirconium added through milling remains dispersed on the particles' surface without forming the desired ternary phase sheds light on the underlying mechanisms at play.
Overall, your Amol Kamble findings provide valuable insights into the intricate interplay between alloy composition, processing methods, and hydrogen absorption kinetics. Keep up the great work, and I look forward to hearing more about your Amol Kamble research endeavors!
