Abstract
The structure of Cu precipitates in a Cu-bearing High Strength Low Alloy steel has been characterized by using high resolution electron microscopy and with the combined use of a computer-aided image processing system. The twinned 9R and distorted intermediate structures were found in the precipitates smaller than about 10 nm in diameter. In the precipitates of about 15 nm in diameter, two kinds of structures, which are the 3R transformed from 9R and the multitwinned f.c.c. formed directly from coherent b.c.c. particle by the lattice shear deformation were observed. The f.c.c. precipitates have a Kurdjumov-Sachs orientation relationship to the matrix, and the diffuse characterization of atoms was observed within twin band with 2-3 atomic layers is observed. The distorted f.c.c. structure was found in rod shaped precipitates of about 30 nm in length.
