Recently, Zhangjing, a doctoral student at the School of Materials Science and Engineering of Shandong University, was awarded the 2011 gold medal of Organization Characterization Award, issued by the Korean Institute of Metals and Materials. Her topic was "the stacking faults and twins on the surface of silicon in eutectic Al-Si alloy."

The institute was impressed with her research and noted that "it provides observation for modified eutectic silicon on the atomistic level."

As the joint-training doctoral student of Shandong University and Korea Institute of Materials Science (KIMS), Zhang Jing has been carrying out her scientific research on "the metamorphic mechanism and microstructure control of eutectic silicon in horizontal continuous casting Al-Si alloys based on structural inheritance" from July 2009 to July 2011 on South Korea’s KIMS campus.

In order to investigate the early-stage growing characteristic of modified eutectic silicon，Zhang Jing prepared the specimen through fast quenching once modifying treatment, and screened out the growth characteristics in early stage of primary silicon by high resolution transmission electron microscopy. To receive such an award from the Korean Institute of Metals and Materials is a testament to Zhang Jing’s scientific acumen is an honor on behalf of all the joint-training doctoral students of Shandong University whom she represents.
