Abstract:

In oder to obtain useful information about the improvement of mechanical properties of Fe-30(mass)%Cr-5%Al alloys containing Ce, some examinations were made on these alloys, as cast and as rolled, using various techniques such as the tensile test, optical microscopy, electron prove microanalysis and X-ray diffraction.
The experimental results are as follows.
