摘要：
The phenomenon of "475-degrees-C embrittlement" of Fe-Cr-Ni alloys with Fe/Cr ratios of 2.7 and 1.05, containing 0, 2 and 4 at.% Ni, has been investigated using the Mossbauer effect and hardness measurements. The results show that the addition of nickel to Fe-xCr alloys (x = 25 and 45 at.%) increases the transformation rate notoriously in the first hours of aging, the effect of this element being more important for alloys with Fe/Cr = 1.05.
