1Effect of Cooling Rate and Vanadium Content on the Microstructure and Hardness of Medium Carbon Forging Steel显示文摘This paper reports the effect of cooling rate on the microstructure and hardness of a kind of medium carbon steel microalloyed with two levels of V content(0.15%and 0.28%)after hot deformation by using single compression tests on a Gleeble-3800 thermal simulator.The results show that cooling rate has a significant effect on the microstructure and hardness of the tested steels.Both the fraction of pearlite and hardness increase with increasing cooling rate,whereas a further increase of the cooling rate above a critical value promotes the formation of acicular ferrite(AF),and thus leads to a decrease of hardness mainly owing to the decrease of pearlite fraction and replacing it by AF and the less effective precipitation strengthening.Increasing V content results in a significant increase of hardness,and this tendency enhances with increasing cooling rate until the formation of AF.Furthermore,increasing V content also significantly enhances the formation of AF structure at a lower cooling rate.The results also suggest that by controlling microstructure,especially the precipitation of fine V(C,N)particles through adjusting postforging cooling,the strengthening and gradient function in one hot-forging part could be obtained.Weijun Hui Yongjian Zhang Chengwei Shao Silian Chen Xiaoli Zhao Han Dong 2016Journal of Materials Science & Technology2016,32,6:7

4Ice-volume and insolation influences on hydroclimate changes in central eastern China during the antepenultimate glacial period显示文摘The rainfall changes in East Asian summer monsoon(EASM)regions on the orbital timescale remain controversial due to the lack of reliable rainfall records.Here,we present new multiproxy records(δ^(18)O,δ^(13)C,Sr/Ca and Mg/Ca)of a230Thdated stalagmite from Hulu Cave in central eastern China.Multiproxy records reconstruct a regional hydroclimate history from 340 to 261 kyr BP(thousand years before present),approximately covering the antepenultimate glacial period.Theδ^(18)O record is dominated by the precessional cycles,suggesting that EASM responds to changes in Northern Hemisphere summer insolation(NHSI)on the orbital timescale.Significant correlations amongst theδ^(13)C,Sr/Ca and Mg/Ca suggest that a common factor,i.e.,the local hydrological cycle,controlled their variability,and their leading principal component can be used as a proxy linked to regional rainfall.This composite record bears a good similarity to those from the Chinese Loess Plateau,showing a gradually decreasing rainfall during the antepenultimate glacial period,consistent with changes in global ice volume.Superimposed on the long-term trend,three relative wetter intervals were responding to the higher NHSI periods,suggesting that EASM rainfall variability was induced by integrated effects of global ice volume and NHSI.The increased ice sheets and lower NHSI resulted in an increased meridional temperature gradient and southward shift of the westerlies,which shortened the duration of Meiyu and midsummer rainfall.The differences between the rainfall record and the stalagmiteδ^(18)O record indicate that the latter represents the overall EASM intensity linked to monsoon circulation,but does not directly reflect the rainfall changes at the cave sites.Quan WANG Shayue YUAN Yijia LIANG Kan ZHAO Qingfeng SHAO Zhenqiu ZHANG Junji ZHU Xinggong KONG Yongjin WANG Jianghu LAN Hai CHENG Chengwei XIA Yi LI 2023Science China Earth Sciences2023,66,1:0
