摘要
The effects of cold deformation on recrystallization characteristics of a mechanically alloyed yttria dispersion strengthened alloy (Fe 20%Cr 4.5%Al 0.5%Ti 0.01%C 0.5%Y 2O 3 (wt%)) are studied. Experimental techniques employed include optical and transmission electron microscopy (TEM), differential scanning calorimetry (DSC), and laser processing methods. In addition, a recrystallization grain growth model is presented to explain the observed reduction of recrystallized grain aspect ratio as a result of cold forging.
