In the present work, the effect of beryllium on microstructure, corrosion and melting temperatures in Ni-Cr-Mo-Co alloys was studied. The study consisted in obtaining several alloys through meltings under vacuum, followed by wrought in industrial conditions. After wrought, the alloys were thermally treated under several temperatures and cooled in water, air and furnace. The presence of beryllium in the Ni-Cr-Mo-Co alloys changes the microstructure, producing intermetallic phases. It was observed that in the studied alloys the presence of beryllium decreases melting temperatures and promotes pite corrosion
