| 1 | The role of Al_(2)Y in grain refinement in Mg-Al-Y alloy system显示文摘A series of Mge10(AlþY)alloys with various weight ratios of Al to Y were cast to investigate the role of Al_(2)Y in grain refinement in MgeAleY ternary system.Thermal analysis combined with microstructural and EDX analysis was used to determine the phase transformation temperatures during solidification process.Experimental results show that when the Al content is below 4 wt%,a peritectic reaction,LþAl_(2)Y/a-Mg,occurs after the intermetallic Al_(2)Y forms directly from the melt as a pro-peritectic phase.Once the Al content is above 4 wt%,an eutectic reaction occurs at a lower temperature.The presence of the pro-peritectic phase can lead to nucleation of a-Mg directly through a peritectic reaction although grain refining efficiency is also closely related to the active particle size.In the case where solidification does not involve a peritectic reaction,the growth restriction factor,quantitatively the Q-value,governs the grain refining efficiency.Higher Q-value corresponds to finer grains. | H.-W.Chang D.Qiu J.A.Taylor M.A.Easton M.-X.Zhang | 2013 | Journal of Magnesium and Alloys2013，1，2： | 10 |
| 2 | An analysis of the China–US trade war through the lens of the trade literature显示文摘The current China–US trade war that started in early 2018 has been the largest of this kind in the global market in the past half century,if not longer.Many speculations about the reasons for and progress and potential implications of the trade war emerge.Countries must understand the reasons for the war to avoid future trade wars.Predicting what will happen in the near future and the related economic consequences are even more important for people(including businessmen and government policymakers)to prepare for them and make corresponding decisions.However,endeavouring to predict is a tough job.This paper tries to provide an unbiased analysis through the lens of the trade literature.That is,we want to ask how much we can understand the current trade war on the basis of the accumulated knowledge we can obtain from our profession.Related theories include imperfect competition,increasing returns,terms of trade argument,distributional effects and political economy argument. | Larry D.Qiu Chaoqun Zhan Xing Wei | 2019 | Economic and Political Studies2019，7，2： | 6 |
