Representative work: In this work, effects of rare earth addition on mechanical properties and corrosion behavior of GCr15 bearing steel under hot rolled, annealed, and quenched-tempered conditions were investigated via mechanical tests, electrochemical measurements, and immersion tests. Results show that rare earth elements can refine grains, improve hardness, tensile strength, and impact absorption energy of GCr15 bearing steel under different heat treatment conditions. Besides, it has been found that rare earth elements are beneficial to corrosion resistance of GCr15 bearing steel in 0.1 mol/L NaCl solution by electrochemical and immersion measurements Nickel-base alloy is a type of metal material with excellent properties and is widely used in many fields. However, in the harsh environment of the acid solution, corrosion causes the reduction of the service life of the alloys, thereby limiting the alloys' use and development. In this paper, the effect of Chromium (Cr) content on the microstructure and corrosion behavior of nickel-based alloys in hydrochloric acid (HCl) was studied by scanning electron microscopy (SEM), energy dispersive
