论文标题Oxidation behavior of AlN-SiC-TiB2 ceramics synthesized by SHS-HIP

作者Zhou, Lijuan; Zheng, Yongting; Du, Shanyi

期刊名称JOURNAL OF ALLOYS AND COMPOUNDS

期卷v478,n1-2,

简单介绍The present study aims to investigate the oxidation behavior of AlN-SiC-TiB2 composites. synthesized by self-propagating high-temperature synthesis (SHS) and hot isostatic pressing (HIP). Oxidation experiments are carried out in the temperature range from 900 degrees C to 1400 degrees C for 1-16 h under air atmosphere. The evaluation of the oxidation kinetics and the modification of the microstructure on the exposed surfaces are investigated. The weight gain per unit surface area as a function of time increased parabolically with the oxidation time from 900 degrees C to 1400 degrees C and it is accelerated sharply when the temperature is raised up to 1400 degrees C. The oxidation products on the sample surfaces are mainly constituted of crystalline mullite and titanium oxide.


论文标题Microstructure, mechanical properties and thermal shock behavior of h-BN-AlN ceramic composites prepared by combustion synthesis

作者Li HB ; Zheng YT; Han JC ; Zhou LJ

期刊名称JOURNAL OF ALLOYS AND COMPOUNDS

期卷v509,n5,p1

简单介绍h-BN-SiC-AlN-TiN ceramic composites with volume content of AlN-TiN ranging from 20% to 70% were prepared by combustion synthesis from powder compacts of B4C, Si, Al and TiN under 100 MPa nitrogen pressure. The volume fraction of AIN-TiN was found to have a significant influence on the microstructure, mechanical properties and thermal shock resistance of the composites. With the increasing volume content of AIN-TiN, the mechanical properties of the composites were improved remarkably, while thermal shock resistance decreased. Thermal shock tests showed that the critical thermal shock temperature (AT) was higher than 1200 degrees C for the composites with AIN-TiN contents of 30 vol%; while it was decreased to 850 and 670 degrees C for the composites with AIN-TiN contents of 50 and 70 vol%, respectively.


论文标题Effect of reactant Ti/B4C ratio on the stoichiometry and mechanical properties of h-BN-Ti(C,N) prepared by combustion synthesis

作者Li HB, Zheng YT, Han JC,Zhou LJ

期刊名称MATERIALS SCIENCE AND ENGINEERING A

期卷V 528 n6

简单介绍h-BN-Ti(C,N) ceramic composites were prepared by combustion synthesis from B4C-Ti powder compacts ignited under high gaseous nitrogen pressure. The influences of Ti/B4C ratio in reactant on the combustion temperature and velocity, phase composition and N content in Ti(C,N) phase were analyzed through theoretical and experimental studies. Experimental results show that combustion temperature and velocity increased with the increase of Ti/B4C ratio in reactant. TiN is the preferential formation phase under high nitrogen pressure, which resulted in higher N content in Ti(C,N) phase. Mechanical properties of the composites increased with the increase of Ti/B4C ratio because of higher Ti(C,N) content in products. Crown Copyright (C) 2010 Published by Elsevier B.V.

论文标题Microstructure and mechanism of Al2O3-ZrO2 eutectic coating prepared by combustion-assisted thermal explosion spraying

作者Zheng YT, Li HB, Zhou T

期刊名称APPLIED SURFACE SCIENCE

期卷v258 n 4

简单介绍Thin Al2O3-ZrO2 eutectic coating was produced by combustion-assisted thermal explosion spraying using a mixture of Al and Zr(NO3)(4) powders. The cross-sectional microstructure of the coating shows successively amorphous, cellular, and dendrite structure along the direction perpendicular to the Cu substrate. The formation mechanism of the coating structure was analyzed based on the experimental results, and the morphology of different crystal structure was observed by SEM and TEM.


论文标题Combustion synthesis and characteristics of aluminum oxynitride ceramic foams

作者Zheng, Yongting;Li, Hongbo;Zhou, Wei; Zhang, Xiaonan; Ye, Guorui

期刊名称CERAMICS INTERNATIONAL

期卷Volume: 38

简单介绍Aluminum oxynitride (AlON) ceramic foams were prepared by combustion synthesis using Al and Al2O3 as starting materials under high nitrogen pressure. By introducing Al(NO3)(3)center dot 9H(2)O into reactants as active pore-forming agent, AlON ceramic foams with well-distributed pores were cost-effectively fabricated. The influences of Al(NO3)(3)center dot 9H(2)O content on the combustion process, pore content and structure were studied systematically. The experiment results showed that porous AlON ceramics containing evenly distributed and noncontiguous pores were obtained when Al(NO3)(3)center dot 9H(2)O content was 30%, in which the closed porosity of 80% was found by Archimedes@#% method. Pore distribution measured by mercury intrusion porosimetry indicated that pores with several types of diameter were formed in the foams because of the different conditions of pore fusion and molten viscosity.


论文标题Microstructure and mechanical properties of Al2O3/ZrO2 eutectic ceramic composites prepared by explosion synthesis

作者Zheng, Yongting;Li, Hongbo;Zhou, Tao;Zhao, Jing;Yang, Pan

期刊名称JOURNAL OF ALLOYS AND COMPOUNDS

期卷 Volume: 5

简单介绍Al2O3/ZrO2 eutectic ceramics were prepared by explosion synthesis using Al and Zr(NO3)(4) as raw materials. The Al2O3/ZrO2 eutectic microstructure showed that the rod-like ZrO2 phases with a diameter 200 nm were embedded orderly in Al2O3 matrix. With the increasing of the reaction temperature, the volume content of the Al2O3/ZrO2 eutectic increased accordingly, and the diameter and phase spacing of the rod-like ZrO2 decreased, which was mainly attributed to the sufficient diffusion at higher temperature and the large degree of supercooling. Due to the fine microstructure of the Al2O3/ZrO2 eutectic, the Vickers hardness and fracture toughness can reach 17.7 GPa and 10.3 MPa m(1/2), respectively.


论文标题Microstructure and mechanical properties of h-BN-SiC ceramic composites prepared by in situ combustion synthesis

作者Zheng YT，Li HB，Zhou T

期刊名称MATERIALS SCIENCE AND ENGINEERING A

期卷Volume: 54

简单介绍h-BN-SiC ceramic composites were prepared by in situ combustion synthesis of B4C and Si powder compacts under high nitrogen pressure. The high reaction nitrogen pressure was beneficial to the improvement of the relative density and mechanical properties of the products, but higher nitrogen pressure of 120 MPa was favorable to the formation of Si3N4, which was consistent with the theoretical thermodynamic calculation. The h-BN-SiC ceramic composites have good mechanical properties over those of conventionally processed ones because of the in situ formed h-BN and SiC phases fabricated under high temperature and pressure. The bending strength and fracture toughness of the h-BN-SiC ceramic composites prepared under 100 MPa nitrogen pressure were 82 MPa and 1.9 MPa M-1/2, respectively.
