Corrosion Behavior of Brass H62 in Harsh Marine Atmosphere in Nansha Islands, China
Journal of Materials Engineering and Performance, 2020The corrosion behavior of brass H62 exposed to the atmosphere of Nansha Islands for 21 months was investigated by weight loss, scanning electron microscopy, x-ray diffraction and electrochemical techniques. The results showed that the average corrosion rate of brass H62 exposed for 1 year was approximately 13.47 g m−2 a−1, and the corrosion products ...

Constitutive Modeling for Superplastic Flow Behavior of H62 Alloy
Advanced Materials Research, 2014In order to precisely describe superplastic flow behavior of H62 alloy, a empirical constitutive equation was established based on the experimental data, which were obtained from the constant strain rate tensions (2.0×10-4~4.0×10-2s-1) at 720 °C. Through verification of the constitutive equation with the experimental data in constant strain rate ...

On the Size Effects in Micro/Meso Upsetting of Brass H62 at Elevated Temperatures
Key Engineering Materials, 2014Micro/meso forming, as an emerging manufacturing process for miniature metallic workpieces, has attracted great attention since the 1990s due to its high production efficiency, low material waste and high precision. Due to the so-called size effects in the scaling down, many traditional theories in metal forming cannot be simply applied to the micro ...

Research on the Micro-tensile Test on H62 Brass Sheet and Size Effects
2010 International Conference on Electrical and Control Engineering, 2010In order to investigate the effect of grain size and thickness with respect to material mechanical property in the micro-scale, experiments were taken by tensile test on H62 brass sheet metal with different grain sizes and thicknesses. The experiment results show that the flow stress decreases with the decreasing sheet metal thickness, and the flow ...
