“…Copper precipitation has been investigated in model binary and ternary Fe-Cu alloys (Hornbogen & Glenn, 1960;Speich & Oriani, 1965;Goodman et al, 1973aGoodman et al, , 1973bPizzini et al, 1990;Othen et al, 1991Othen et al, , 1994Phythian et al, 1992;Maury et al, 1994;Osamura et al, 1994aOsamura et al, , 1994bCharleux et al, 1996;Monzen et al, 2000Monzen et al, , 2003Monzen et al, , 2004Deschamps et al, 2001Deschamps et al, , 2003, in ASTM A710 and A736 grade Fe-Cu steels (Miglin et al, 1986;Wilson et al, 1988;Thompson & Krauss, 1996;Dhua et al, 2001aDhua et al, , 2001b, and more recently in the NUCu and other experimental Fe-Cu steels (Gagliano & Fine, 2001Isheim et al, 2006b;Vaynman et al, 2008;Mulholland & Seidman, 2009;Mulholland & Seidman, 2011;Farren et al, 2012;Hunter et al, 2013). These studies focused on Cu-rich precipitates located in the matrix phase that were formed during solutionizing and quenching (interphase precipitation) or during isothermal aging.…”
