Effect of nickel content and milling parameters on martensitic transformation of Fe-Ni during mechanical alloying

Effect of nickel content and mechanical alloying parameters on martensitic transformation during mechanical alloying of Fe-Ni was studied in this paper. Both nickel content and the whole transferred energy E-t are two important parameters governing phase transformation during mechanical alloying of Fe-Ni. They respectively decide whether and when the reverse transformation of martensite to austenite occurs. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
