Abstract
The misorientation angle dependence of density and volume of BCC precipitates on symmetric [011] tilt boundaries in a Cu-Fe-Co alloy has been studied to examine a correlation between the boundary precipitation and the boundary energy or the angle of the precipitate habit plane against the boundary plane. In general, the lower the boundary energy, the smaller the number and volume of the boundary precipitates. The minimum of the density and volume occurs where the cusps of the boundary energy exist ; θ=70.5° (Σ3) and 130° (Σ11). It has been found that the boundary energy plays a strong role in governing the boundary precipitation.
