title = "Effects of W micro-additions on precipitation kinetics and mechanical properties of an Al–Mn–Mo–Si–Zr–Sc–Er alloy",
abstract = "A micro-addition (0.025 at.%) of slow-diffusing W to an Al-0.26Mn-0.11Mo-0.11Si-0.08Zr-0.02Sc-0.01Er (at.%) alloy accelerates L12-Al3(Zr,Sc) precipitation but retards α-Al(Mn,Mo)Si precipitation. The W micro-addition increases the peak-microhardness of the alloy during isothermal aging but does not improve the coarsening resistance and creep resistance.",

Atom-probe tomography was performed at the Northwestern University Center for Atom-Probe Tomography (NUCAPT). The LEAP tomograph in NUCAPT was purchased and upgraded with funding from NSF-MRI ( DMR-0420532 ) and ONR DURIP ( N00014e0400798 , N00014e0610539 , N00014-0910781 , N00014-1712870 ) programs. Instrumentation at NUCAPT was partially supported by the Initiative for Sustainability and Energy at Northwestern University (ISEN). This work made use of the MatCI Facility and the EPIC facility (NUANCE Center) at Northwestern University. NUCAPT, MatCI and NUANCE received support from the MRSEC program ( NSF DMR-1720139 ) through Northwestern's Materials Research Center; NUCAPT and NUANCE also benefitted from the Soft and Hybrid Nanotechnology Experimental (SHyNE) Resource ( NSF NNCI-1542205 ). NUANCE received support from the International Institute for Nanotechnology (IIN); the Keck Foundation; and the State of Illinois, through the IIN.
