Shifeng Liu is an Associate Professor from Chongqing University (China). His present research interests mainly focus on plastic deformation, microstructure and the texture of metals and alloys. He has been engaged in material processing and characterization since the completion of his bachelor studies at Central South University in 1998. In the past two decades, he has been involved in multiple projects related to ceramics, metals and alloys, particularly the high-purity tantalum sheets used for sputtering targets in the IC industry. The high-performance tantalum target has been successfully commercialized through optimizing the rolling and annealing process of tantalum ingots.
