Rare earth can influence for shape size,distribution and quantity of niobium carbonide,decrease activity of carbon and niobium i...

稀土对碳形态、大小、分布、数量有影响,可降低碳、活度,阻碍碳体区的析出。

Using the modified analytic embedded-atom method (MAEAM), the molecular dynamics (MD) simulation was performed to study the premelting and melting behavior of (001) plane of niobium and tungsten.
