研究了Fe-1.4at. Cu析出初期析出相的尺寸和数量密度。用场离子显微镜（SEM）测定500°C下的pct Cu。虽然小于50 × 10− 8 cm的粒子在电子显微镜（ETM）中仍然不可见，但它们可以被电子显微镜清晰地分辨出来;直径小至8 × 10− 8 cm的粒子可以被检测到。颗粒的生长速率可以通过正常的体扩散来解释。在最高强度时，合金每立方厘米含有约1018个颗粒，平均直径为24 × 10− 8厘米。合金在沉淀完全之前达到其峰值强度。
The size and number density of precipitates formed during the early stage of precipitation of copper from Fe-1.4 at. pct Cu at 500°C was determined with the field-ion microscope (FIM). While particles of less than 50 × 10−8cm remain invisible in the electron microscope (ETM) they are clearly resolved with the FIM; particles as small as 8 × 10−8cm in diameter could be detected. The growth rate of the particles can be accounted for by normal bulk diffusion. At its peak strength, the alloy contains approximately 1018particles per cu cm with an average diameter of 24 × 10−8cm. The alloy reaches its peak strength well before precipitation is complete.
