High temperature oxidation resistance of 4TaC-HfC/LaB6 composite

Autor: Fen Zhang, Aizhi Sun, Xianghui Yue, Chen Tong

Publikováno v: Results in Materials, Vol 8, Iss , Pp 100136- (2020)

In this paper, 4TaC-HfC/LaB6 composite was prepared by spark plasma sintering (SPS), and its oxidation resistance was significantly improved by vacuum heat treatment process. The result shows that the oxidation weight gain rate of SPSII sintered samp

Microstructure evolution and coercivity mechanism of hydrogenation-disproportionation-desorption-recombination (HDDR) treated Nd-Fe-B strip cast alloys

Autor: Xuexu Gao, Aizhi Sun, Xiaoqian Bao, Jiheng Li, Bin Ma

Publikováno v: Journal of Rare Earths. 40:792-799

In this paper, we systematically investigated the microstructure evolution and coercivity mechanism of hydrogenation-disproportionation-desorption-recombination (HDDR) treated Nd-Fe-B strip cast alloys by transmission electron microscopy (TEM) and th

Effect of Rare Earth Element Ce and Heat Treatment Process on Impact Toughness and Microstructural Developments of 27Co-Fe Alloy

Autor: Yuhui Wang, Fen Zhang, Wenjiang Qiang, Keke Xing, Aizhi Sun

Publikováno v: Journal of Materials Engineering and Performance. 30:8551-8559

A systematic study of impact energy, microstructure, fracture section and residual stress of 27Co-Fe was carried out using charpy impact tester, metalloscope, scanning electron microscope and x-ray residual stress detector. The forged C27, C27R1 and

Gridded pollen-based Holocene regional plant cover in temperate and northern subtropical China suitable for climate modeling

Autor: Furong Li, Marie-José Gaillard, Xianyong Cao, Ulrike Herzschuh, Shinya Sugita, Jian Ni, Yan Zhao, Chengbang An, Xiaozhong Huang, Yu Li, Hongyan Liu, Aizhi Sun, Yifeng Yao

We present the first gridded and temporally continuous quantitative pollen-based plant-cover reconstruction for temperate and northern sub-tropical China over the Holocene (11.7 ka BP to present) using the Regional Estimates of Vegetation Abundance f

Holocene vegetation and hydrology variations and their associations with climate changes: a multi-proxy analysis of a sediment core from an alpine basin in the middle Tianshan Mountains

Autor: Dongliang Zhang, Zhaodong Feng, Bo Lan, Min Ran, Aizhi Sun, Yunpeng Yang

Publikováno v: Climate Dynamics. 56:3835-3852

We in this paper present a multi-proxy study of a 186-cm-long lacustrine sediment core (i.e., BY Core) obtained from the Youerdusi Basin in the middle Tianshan Mountains in an attempt to disentangle the causal associations among climate changes, ecol

Normal and Abnormal Grain Growth in Hydrogenation-Disproportionation-Desorption-Recombination Processed Nd–Fe–B Strip-Cast Alloys

Autor: Jiheng Li, Aizhi Sun, Bin Ma, Xuexu Gao, Cao Shuai, Xiaoqian Bao

Publikováno v: Crystal Growth & Design. 20:3119-3130

Abnormal grain growth (AGG) is a common phenomenon in liquid-phase sintering of Nd–Fe–B materials. To identify the growth mechanism and suppress AGG, we investigated the grain growth in hydrogenati...
