Studies from P.R. Monasterio and colleagues yield new information about physics
September 29th, 2009
According to a study from the United States, "Energetics and concentrations of hydrogen-containing point defect clusters (PDCs) in Fe-C alloys are calculated and cast into a PDC dominance diagram."
"Because of the strong binding effects of iron vacancies on the stability of the clusters, hydrogen accumulation requires the total hydrogen and vacancy concentrations to be comparable. As a result of the interplay between repulsive and attractive binding processes, PDC populations in Fe-C-H effectively decouple into the binary systems Fe-C and Fe-H," wrote P.R. Monasterio and colleagues.
The researchers concluded: "This results in significant vacancy-hydrogen...
