Comparative study of intermetallic phases formed by direct ion implantation and radiation enhanced diffusion of tin in two kinds of steel
(1985) [Artigo de periódico]The surface layers of high-carbon and stainless steel samples, treated by both direct ion implantation of Sn + ions and radiation enhanced diffusion of tin, are analyzed by means of Rutherford backscattering and 119Sn and ... -
Intermetallic phases formed during tin implantation into iron and steels
(1984) [Artigo de periódico]The surface layers of pure iron, high-carbon steel and stainless steel, ion implanted with 1 X 1017 Sn+ cm-² , have been characterized by means of 119Sn conversion electrons Mossbauer scattering. The intermetallic phases ... -
Low-temperature iron-nitride phase transformations induced by ion bombardment
(1996) [Artigo de periódico]We show that for the Fe–N system the combined use of ion irradiation and thermal annealing can lower the temperature for a given phase transformation. By Ar bombarding N-implanted Fe samples at 250 and 300 °C, we have ... -
