Effect of Niobium on the Formation of Microstructure and Grain Boundary in Fe–Nb and Fe–C–Nb Alloys

Peritectic Transformation in Low Carbon Steels Containing High Phosphorus Concentration

“…Phase indentation of the d and g phases was carried out by microstructure observation and phosphorus concentration profiles, which are the same methods reported in other studies. [15][16][17] 3. Results and Discussion…”

“…We further studied the correlation between the dendritic morphology of the d phase and the grain growth of the g phase when peritectic transformation occurs in Fe-1.0mass%C-Nb alloys with various niobium concentrations. 17) As a result, the boundary of the g grains formed in the spacing between the respective groups of the dendritic arrays, which had different growth directions, in the Fe-1.0mass%C-Nb alloys over 1.0 mass% Nb. This must be because the shape of the group of primary d dendrites was indicated the shape of the g grain.…”

Electrochemical Synthesis of Core–Shell-Structured NbC–Fe Composite Powder for Enforcement in Low-Carbon Steel

“…In particular, NbC powder is used as an additive into other metals or alloys to strengthen the mechanical properties of these materials [ 4 , 5 , 6 , 7 ]. The composites consisting of metal and ceramic particle reinforcements play an essential role in the production of cost-competitive and environment-friendly materials [ 8 , 9 , 10 ]. An addition of ceramic particles can guarantee both hardness and wear resistance of the matrix.…”
