摘要
X-ray studies were carried out on an inert gas atomized low carbon (LC) astroloy powder. The as-atomized powder was sieved into different fractions of narrow size using suitable combination of sieves to study the effect of particle size on the compositional homogeneity and lattice parameter. Using a slow scanning X-ray diffraction technique, the lattice parameter of the sample and broadening of the X-ray reflections were determined for different fractions. The results showed systematic variations with average particle size. The dendrite arm spacings measured by optical metallography showed a direct correlation with the average particle size. The observed broadening has been found to be due to the inhomogeneity in composition of the alloy developed during atomization. (C) 2004 Published by Elsevier B.V.
