Study on the Damage Mechanism of an H62-Cu/7075-Al Tribo-Pair Under the Influences of Current Direction and Density. [PDF]
Materials (Basel)In the present study, we used 7075 Al-H62 Cu and H62 Cu-7075 Al pairs to study the effects of current density and direction on their tribological properties and on the damage caused by the current-carrying friction and wear.

Characteristics of microstructure evolution of two-phase H62 brass alloy during continuous extrusion
Procedia Engineering, 2017 Abstract The initial grains of H62 brass alloy are refined after continuous extrusion, and the dynamic recrystallization occurs in the forming process. Mastering the driving forces of microstructure evolution are the key for exploring the deformation characteristics of two-phase H62 brass during continuous extrusion.

Rare Metal Materials and Engineering, 2017 Abstract Uniaxial tensile tests were carried out on T2 pure copper plate and H62 copper alloy subjected to identical heat treatment. The influences of different strain states on the damage degree of both materials were analyzed. It is found that the fracture and damage of T2 pure copper and H62 copper alloy are closely related to their microstructure

Materials & Design, 2016 Abstract In this study, friction stir brazing (FSB) was applied to join 6061 aluminum to H62 brass with the aid of zinc foil. The thermal history of interface was measured by thermocouple. The interfacial microstructure variations under different welding speeds were analyzed via scanning electron microscopy (SEM) and energy dispersive spectroscopy ...
