contact201691 · 1. Introduction. HAl77-2 aluminum brass (UNS C68700) alloy, as the material of condenser and heat exchanger tube, has been widely used in thermal power, petrochemical industry, desalination and other fields due to its high strength, good thermal conductivity and excellent corrosion resistance (Trostmann and Morin, 2010).During cold
contactWith increasing grain size, both the yield strength and ultimate tensile strength of the columnar-grained HAl77-2 brass decreased, but its elongation to failure increased significantly from 70.4% for the grain size of 2.0 mm to 84.4% for the grain size of 6.0 mm. Higher performance to resist the plastic instability and better deformation ...
contactThe corrosion inhibition of the phytic acid on HAl77-2 brass was significantly increased with the addition of sodium molybdate. Besides, the synergistic action of phytic acid and sodium molybdate can weaken the dezincification of brass obviously. These results provide theoretical support for the application of the self-assembled monolayer of ...
