| 1 | Effects of Gd solutes on hardness and yield strength of Mg alloys显示文摘Relative contribution of individual strengthening mechanisms to the yield strength of Mg–0–15 wt%Gd alloys were investigated.Alloys with different grain size were prepared by adding Zr and hot extrusion.Hardness and tensile/compression yield strength were tested on the alloys after solid solution treatment and extrusion.HallPetch constants were calculated with hardness and tensile/compressive data.The results showed that the hardness of Mg–Gd alloys with similar Gd content and different grain size were almost the same,which indicates that grain size had little effect on hardness.The hardness linearly increased with rising Gd content(d H_v/dc≈25 kg mm^(-2)/at%Gd).The tensile and compressive yield strengths enhanced with the increase of Gd content for all alloys in different conditions.In addition,the tensile/compressive(t/c)yield asymmetry of extruded alloys decreased with increasing Gd content.Large t/c yield asymmetry ratio(1.77)was observed for pure Mg,and with increasing Gd content this value decreased to 1.With the increasing of tensile strength,the stress intensity factor,k_y,decreased from 0.27 MPa m^(1/2)for Mg–2 wt%Gd alloy to 0.19 MPa m^(1/2) for Mg–5 wt%Gd alloy,then increased to 0.29 MPa m^(1/2) for Mg–15 wt%Gd alloy.However,k_yincreased linearly form 0.16–0.31 MPa for compression test.The influence of grain size strengthening was eliminated,and the yield strength of tension and compression both linearly increased with c^n,where c is the atom concentration of Gd,and n=1/2 or 2/3. | Yuling Xu Felix Gensch Zhen Ren Karl Ulrich Kainer Norbert Hort | 2018 | Progress in Natural Science:Materials International2018，28，6： | 8 |
| 2 | Soil temperature modifies effects of soil biota on plant growth显示文摘Aims Plants directly and indirectly interact with many abiotic and biotic soil components.Research so far mostly focused on direct,indi-vidual abiotic or biotic effects on plant growth,but only few studies tested the indirect effects of abiotic soil factors on plant growth.therefore,we investigated how abiotic soil conditions affect plant performance,via changes induced by soil biota.Methods In a full-factorial experiment,we grew the widespread grass Dactylis glomerata either with or without soil biota and investigated the impact of soil temperature,fertility and moisture on the soil biota effects on plant growth.We measured biomass production,root traits and colonization by arbuscular mycorrhizal fungi as well as microbial respiration.Important Findings We found significant interaction effects between abiotic soil con-ditions and soil biota on plant growth for fertility,but especially for soil temperature,as an increase of 10°c significantly changed the soil biota effects on plant growth from positive to neutral.However,if tested individually,an increase in soil temperature and fertility per se positively affected plant biomass production,whereas soil biota per se did not affect overall plant growth,but both influenced root architecture.By affecting soil microbial activ-ity and root architecture,soil temperature might influence both mutualistic and pathogenic interactions between plants and soil biota.Such soil temperature effects should be considered in soil feedback studies to ensure greater transferability of results from artificial and experimental conditions to natural environmental conditions. | Johannes Heinze Sabine Gensch Ewald Weber Jasmin Joshi | 2017 | Journal of Plant Ecology2017，10，5： | 3 |
