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 ...

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 ...
