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 ...

Constitutive modeling of hot deformation behavior of H62 brass
Materials Science and Engineering: A, 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 ...

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 ...

The cylinder block/valve plate interface in the axial piston pump has been proven to be easily worn out, which will increase power loss and reduce its efficiency. The valve plate surface is required to be manufactured with low viscous friction and wear.

Fatigue crack initiation life of fine grain brass H62
Theoretical and Applied Fracture Mechanics, 2010Fine grain alloys possess excellent properties entailing high strength and toughness. Fine brass H62 is made by re-crystallization with grain size ranging from 5 to 10 μm. Fatigue initiation life is investigated from specimens tested on Instron 1341 machine a frequency of 30 Hz.

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 ...
