Brass H62 Hot Extrusion of Micro Gear

Materials Science Forum, 2011
Gears are very important and widely used driving components in mechanical instruments, and the demands of micro-gears are increasing more and more active as the MEMS technology develops in recent years. In this paper, a brass micro gear, which modulus m = 0.125 mm, pressure angle α = 20°, number of teeth z = 6, addendum circle diameter d = 1 mm, hot ...

Experimental Study of Hot Extrusion Micro Gear of Brass H62

Advanced Materials Research, 2011
A new micro-forming method, combining a metal’s super-plastic behavior with hot extrudsion technology, has been developed for manufacturing micro-gear from brass H62. The micro-gear, which modulus m = 0.125mm, pressure angle α = 20°, number of teeth z = 6, tip diameter d = 1mm, was selected and its dies were designed with a better die approach angle ...

Constitutive modeling of hot deformation behavior of H62 brass

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2011
Abstract 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 ...

Fabrication of superhydrophobic surface with enhanced corrosion resistance on H62 brass substrate

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2020
Abstract 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.

Effects of Grain Refiner and Cooling Rate on Solidification Structure of H62 Brass

Advanced Materials Research, 2013
In this paper, effects of different grain refiners on solidification structure of H62 brass under different cooling rates were investigate by macro corrosion, SEM and EDX analyses. Results of experiments indicate that the columnar crystal zone of H62 brass is completely eliminated and the grain size is reduced remarkably by 0.01%B.

Equivalent strain, microstructure and hardness of H62 brass deformed by constrained groove pressing

Computational Materials Science, 2011
Constrained groove pressing (CGP) has been developed to refine grain sizes, and in most cases is conducted under partially constrained conditions. Here we report the first investigation of the Von Mises equivalent strain and its distribution in samples subject to CGP under partially constrained conditions.
