Autor: Zhixia Xiao, Honglve Yang, Rui Xu, Baoxi Liu, Jianhang Feng, Puguang Ji, Jia Liang, Guoxin Liang

Publikováno v: Journal of Materials Research and Technology, Vol 30, Iss , Pp 3141-3151 (2024)

Oxide particles with suitable size can refine the microstructure and improve the strength and toughness of steel. In this study, the particles containing Al2O3 were successfully introduced into H13 steel by vacuum casting. The micro-sized Al2O3-conta

Bioinspired fibrous microstructure breaks strength and toughness trade-off in plain carbon steel

Autor: KuanYuan Fan, Bo Yang, BaoXi Liu, TianLong Liu, PuGuang Ji, FuXing Yin, ZhiChao Luo

Publikováno v: Journal of Materials Research and Technology, Vol 25, Iss , Pp 6853-6864 (2023)

Warm rolling at eight temperatures was conducted on two mixed ferrite-pearlite initial microstructures in order to develop strong but tough plain steel. The obtained wood-like fibrous microstructure in AISI 1045 plain steel breaks the strength and to

Effect of Strain Rate on Compressive Properties of Aluminium-Graphene Composites

Autor: Yufu Yan, Jiamin Zhao, Long Chen, Hongjian Zhao, Olga Klimova-Korsmik, Oleg V. Tolochko, Fuxing Yin, Puguang Ji, Shaoming Kang

Publikováno v: Metals, Vol 13, Iss 3, p 618 (2023)

Graphene-reinforced aluminium composites have been widely studied due to their excellent mechanical properties. However, only a few studies have reported their dynamic compression properties. The purpose of this study is to investigate the quasi-stat

Effect of 1wt%Zn Addition on Microstructure and Mechanical Properties of Mg-6Er Alloys under High Strain Rates

Autor: Hui Yu, Junchao Ren, Shaoming Kang, Wei Yu, Zhifeng Wang, Jianhang Feng, Qingzhou Wang, Puguang Ji, Xin Zhang, Fuxing Yin

Publikováno v: Metals, Vol 12, Iss 5, p 883 (2022)

In this study, we investigated the high strain rate response of Mg-6wt%Er alloys with 1wt%Zn addition by split Hopkinson pressure bar (SHPB) tests in a range of 900–2500 s−1. Their related microstructures were also characterized by optical micros

Transformation Induced Plasticity Effects of a Non-Equal Molar Co-Cr-Fe-Ni High Entropy Alloy System

Autor: Wei Fang, Ruobin Chang, Puguang Ji, Xin Zhang, Baoxi Liu, Xuanhui Qu, Fuxing Yin

Publikováno v: Metals, Vol 8, Iss 5, p 369 (2018)

Abstract: Metastability-engineering strategy is an important topic for high entropy alloys (HEAs), owing to the transformation-induced plasticity effect (TRIP). In this work, TRIP effects of Co-Cr-Fe-Ni HEAs are investigated. Results indicate the ten
