Effect of milling temperature on nanoclusters and ultra fine grained microstructure of oxide dispersion strengthened steel.

Highlights: [•] Low temperature milling effectively decreased grain size. [•] Low temperature milling was very effective in oxide particle size reduction. [•] Homogeneous distribution of Y2O3 was very important for fine microstructure. [•] Tensile strength was significantly increased by low temperature milling. [Copyright &y& Elsevier]
