Microstructure and Properties of β-TCP Reinforced Zn-Mg Matrix Composites

Autor: Yongjin HU, Wenxian WANG, Zeqin CUI

Publikováno v: Taiyuan Ligong Daxue xuebao, Vol 53, Iss 5, Pp 807-812 (2022)

Pure zinc has good biocompatibility and moderate degradation rate, but its mechanical properties are not ideal, which limits its biomedical applications. In view of the poor mechanical properties of zinc and its alloys, high-energy ball milling and s

Microstructure Evolution and Control of Mechanical Properties of AlCoCrFeNi2.1 Eutectic High-entropy Alloys Prepared by Spark Plasma Sintering

Autor: Liwei LAN, Zeqin CUI, Wenxian WANG, Xiaohu HAO

Publikováno v: Taiyuan Ligong Daxue xuebao, Vol 53, Iss 5, Pp 793-799 (2022)

AlCoCrFeNi2.1 eutectic high-entropy alloys (EHEAs) were prepared by spark plasma sintering (SPS) technology at different sintering temperatures (900, 1 000, 1 100, 1 200 ℃) at a constant pressure of 40 MPa. The effects of temperature on the densifi
