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.

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.

Dissimilar Welding of H62 Brass-316L Stainless Steel Using Continuous-Wave Nd:YAG Laser

Materials and Manufacturing Processes, 2014
Continuous-wave Nd:YAG laser welding of H62 brass and 316L stainless steel was studied using welded joints made with different overlap configurations. Optical and scanning electron microscopies, energy-dispersive X-ray spectroscopy, and microhardness testing were used to analyze the microstructures and mechanical properties of the joints.

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.

Research on the Micro-tensile Test on H62 Brass Sheet and Size Effects

2010 International Conference on Electrical and Control Engineering, 2010
In 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 ...
