Effect of Second Phase Particles on Grain Growth for Nanocrystalline AZ31 Mg Alloy by Phase Field Methods 作者:Wu, Y (Wu, Yan)[ 1 ] 编者:Gu, JW; Chen, XL; Liu, EH 2015 INTERNATIONAL CONFERENCE ON ENERGY, MATERIALS AND MANUFACTURING ENGINEERING (EMME 2015) 丛书: MATEC Web of Conferences 卷: 25 文献号: 02006 DOI: 10.1051/matecconf/20152502006 出版年: 2015 会议名称 会议: International Conference on Energy, Materials and Manufacturing Engineering (EMME) 会议地点: Kuala Lumpur, MALAYSIA 会议日期: OCT 15-16, 2015 摘要 The grain growth of nanocrystalline AZ31 magnesium alloy containing spherical particles with different sizes is simulated by phase field methods. It is shown that the role of pinning effect of the second phase particles during grain growth is interesting. There is a critical particle size to affect the grain growth in nanostructure. If the size of particles is lower than the critical value, the effect of pinning for grain growth will be increased with further decreasing the size. If the size is larger than the critical value, the particles nearly have no pinning effects. The critical value is 200 nm when the content of particles is 10%. It is found that the grain growth exponents in kinetic equation decrease when the sizes of particles increase in nanostructure with the same volume fraction of the particles, and the pinning effect of particles on the grain growth is decreased as well. 关键词 作者关键词:phase field methods; second phase particles; nanocrystalline structure; grain growth KeyWords Plus:2ND-PHASE PARTICLES; SIMULATION; MODEL; RECRYSTALLIZATION; REFINEMENT |
