摘要：

Fe-based bulk metallicglasses of Fe69.9-x,C7.1Si3.3B5.5P8.7CrxMo2.5Al2.0Co1.0 (x = 0.0, 2.3-12.3) with high glass forming ability and good corrosion resistance were fabricated using industrial raw materials. Class forming ability of the Fe-based bulk metallic glasses tends to decrease with the Cr content while the corrosion, resistance increases with the Cr content. A homogeneous passive layer on the amorphous sample with 12.3 at% Cr can be formed leading to superior corrosion resistance of the amorphous sample to an austenitic stainless steel (SUS304) in the 0.5 M H2SO4 and 1N HCl solutions at 298 K. Fe-based bulk metallic glasses with an optimum combination of glass forming ability and corrosion resistance can be produced in large quantities through a systematic control of the Cr content for extensive practical applications.
