Phase transformations in nitrogen implanted iron layers


Phase transformations in nitrogen implanted iron layers

Jagielski, J.; Kopcewicz, J.; Matz, W.; Grötzschel, R.; Thomé, L.

It has been found that phase transformations in implanted iron may strongly depend on the sample thickness. The effect essentially relies on lower impurity concentration required for given phase formation in thin films when compared with thick layers or bulk samples and most likely should be attributed to the stress formed during layer deposition. The phase transformation in thin films is also more complete, for example full transformation of thin iron layers into iron nitrides was observed, whereas in thick and bulk samples about 20 % of Fe atoms in implanted layer remain in crystalline alpha-Fe phase.
