Constitutive modeling of hot deformation behavior of H62 brass
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2011Abstract The hot deformation behaviors of H62 brass are investigated by isothermal compression tests on a Gleeble 1500 thermal-mechanics simulator in the temperature range of 650–800 °C and the strain rate range of 0.01–10 s −1 . Most of the stress–strain curves exhibit a single peak stress, indicating a typical dynamic recrystallization (DRX ...

Journal of King Saud University - Science, 2023 Fabrication of superhydrophobic surface with enhanced corrosion resistance on H62 brass substrate
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2020Abstract Corrosion protection of metals plays an important role in developing economy. Inspired by the lotus leaf in nature, superhydrophobic surfaces with excellent water-repellent properties has great potential to solve corrosion problem. Herein, superhydrophobic surfaces with improved anticorrosion performance were achieved on H62 brass.

Metabolism of glycolic acid by Azotobacter chroococcum PRL H62
Canadian Journal of Microbiology, 1973When Azotobacter chroococcum grows on glycolic acid as sole C source, it cannot utilize N2 and must be provided with reduced nitrogen. Glycolic acid is metabolized via Kornberg's dicarboxylic acid cycle. The TCA cycle enzymes are low in activity, and isocitric dehydrogenase is absent.

Experimental Study of Micro Deep Drawing for H62 Brass
Key Engineering Materials, 2011In this paper, the influence of grain size and blank hold force on micro deep drawing stress and displacement are studied by self-made device. The results show that drawing stress decreases and elongation rate increases with the increase of grain size, the concentrated force area of cylinder-shaped part is transferred from the area punch fillet to die ...

Experiment Research on Grinding Temperature of Micro-Grinding H62
Advanced Materials Research, 2013The thermocouple temperature measurement method was adopted to measure the surface temperature in micro-grinding experiment. According to the different grinding depth, the appropriate processing parameters were chosen to find out the temperature field distribution on the surface and in different depth of subsurface.

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 ...
