| 1 | Tribological Properties of Nanostructured Al/Al_(12)(Fe,V)_3Si Alloys显示文摘Tribological behavior of nanostructured pure Al and Al–Al12(Fe,V)3Si alloys containing 27(FVS0812) and 37(FVS1212) vol% of Al12(Fe,V)3Si precipitates was investigated. All samples were prepared using mechanical alloying followed by hot pressing. Wear tests were performed at room temperature using a pin-on-disk machine. Results showed that the presence of Al12(Fe,V)3Si precipitates increases the wear resistance of nanostructured Al, and the wear resistance increases with increasing the Al12(Fe,V)3Si content. Scanning electron microscopy images of worn surfaces and wear debris demonstrated that abrasion and adhesion are the governing wear mechanisms for the nanostructured FVS0812 alloy at 2 and 5 N normal loads, whereas for the nanostructured FVS1212 alloy, the dominant wear mechanism is abrasion at these loads. A mechanically mixed layer(MML) containing Fe and O was formed on the worn surfaces of FVS0812 and FVS1212 samples at 10 N normal load. Formation and delamination of MML controls the wear behavior of these samples at the normal load of 10 N. It is also found that the presence of Al12(Fe,V)3Si precipitates decreases the friction coefficient of nanostructured Al. | Hamid Ashrafi Mohammad Hosein Enayati Rahmatollah Emadi | 2015 | Acta Metallurgica Sinica(English Letters)2015，28，1： | 4 |
| 2 | Scenario-based estimation of catchment carbon storage: linking multi-objective land allocation with InVEST model in a mixed agriculture-forest landscape显示文摘This study performed a scenario-based land allocation in a mixed agriculture-forest landscape in northern Iran to investigate how different land use policies contribute to changes in carbon storage.In pursuit of this goal,a temporal profile of the trade-off between the region’s land use land cover(LULC)classes was produced using Landsat image of the year 2016.The weighted linear combination procedure was also used to map the suitability of land for agriculture,forest,urban,and rangeland based on ecological and socio-economic criteria.The suitability maps were analyzed through the Multi-Objective Land Allocation procedure under five scenarios with differing areas devoted to each LULC to generate different patterns of LULC distribution in the region.In addition,the Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST)model was used to estimate the potential of LULC classes in carbon storage.The amount of carbon storage differed significantly between the scenarios,ranging from 1.29 tons/ha/year when the majority of the land was devoted to agriculture(76%of the area)to 5.40 tons/ha/year when the landscape was dominated by forest(77%of the area).The extreme conditions presented in this research may not be as likely to occur,but opens a dialog between different stakeholders and informs of a probable trend of ecosystem service loss due to agricultural land expansion. | Rahmatollah Niakan Lahiji Naghmeh Mobarghaee Dinan Houman Liaghati Hamidreza Ghaffarzadeh Alireza Vafaeinejad | 2020 | Frontiers of Earth Science2020，14，3： | 2 |
| 3 | Fabrication and characterization of nanocrystalline Al/Al_(12)(Fe,V)_3Si alloys by consolidation of mechanically alloyed powders显示文摘The aim of this study was to produce bulk nanocrystalline Al/Al_(12)(Fe,V)_3Si alloys by mechanical alloying(MA) and subsequent hot pressing(HP) of elemental powders.A nanostructured Al-based solid solution was formed by MA of elemental powders for 60 h.After HP of the as-milled powders at 550℃ for 20 min,the Al_(12)(Fe,V)_3Si phase was precipitated in a nanocrystalline Al matrix.Scanning electron microscopy(SEM) images of the bulk samples represented a homogeneous and uniform microstructure that was superior to those previously obtained by rapid solidification-powder metallurgy(RS-PM).Nanostructured Al-8.5Fe-1.3V-1.7Si and Al-11.6Fe-1.3V-2.3Si alloys exhibited high HV hardness values of^205 and ~254,respectively,which are significantly higher than those reported for the RS-PM counterparts. | Hamid Ashrafi Rahmatollah Emadi Mohammad Hosein Enayati | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，7： | 2 |
