Graphite growth results in a reduction in the concentration of carbon in the alloy so that eventually it will remain spherical graphite between the austenite grains which will be transformed into pearlite.
Increasing the number of pearlite phase means an increase of cementite phase in the material.

Despite a large number of fundamental efforts were dedicated to the DRX behaviors of the Mg alloys, few works were conducted to apply the DRX models into the FE analysis of the practical extrusion process.
The grain size is fine.

It was obvious that the appropriate addition of ZrO2 could enhance the BET surface area of Co/Al2O3 catalysts, possible because ZrO2 prevented Al2O3 to generate the large grains.
It could be seen that the olefin/paraffin ratios decreased with the increase of carbon number, indicating that the content of olefins decreased and the content of paraffins increased.

This cellulose was partly depolymerized, low in water content, white, tasteless and pure powder with the average grain size of 20μm.
When pyrolysis happened at 500°C for 5s, the products were mainly organic compounds with carbon number of 2-6.

Wei Xu [13] has employed glycol as reducing agent to synthetize evenly-proportionated globular nanometer Ni with average grain diameter 50~100nm.
Then add 200ml deionized water and stir, and add the citric acid of the number of moles of 2 times metal oxygen ion.

Namely, it is known that the electrochemically active surface of porous structure is distinguishable from outer (directly facing the electrolyte) and inner (pores and loose grain boundaries) parts.
At the highest concentration, the impregnation of carbon surface is dominant, with simultaneous decrease in the number of oxide particles deposited in the intergranular space. 4.
