Title: Stabilizing nanoprecipitates in Al-Cu alloys for creep resistance at 300°C

Abstract

Commercial precipitation-hardened Al-Cu alloys are normally used at temperatures below its ageing temperature of ~225°C, to avoid thermally induced precipitate coarsening and resultant softening. Making such popular Al alloys creep resistant at or above 300°C is thus challenging. Here we present a modified precipitation protocol, exploiting Sc-microalloying and a carefully designed three-step heat treatment to enhance Sc segregation at the matrix/θ'-Al₂Cu precipitate interfaces. The stabilized nanoprecipitates enable an order-of-magnitude reduction in creep rate at 300°C, demonstrating the room for microstructure improvement and the potential for property elevation in traditional engineering alloys through innovative processing coupled with synergetic alloying elements.

Effects of Nb and Ta additions on the strength and coarsening resistance of precipitation-strengthened Al-Zr-Sc-Er-Si alloys

Journal Article Erdeniz, Dinc ; De Luca, Anthony ; Northwestern University Center for Atom Probe Tomography, Northwestern University, 2220 Campus Drive, Evanston 60208, IL ; ... - Materials Characterization

Highlights: • Nb and Ta micro-additions are made to a dilute Al-Er-Sc-Zr-Si alloys. • Zr-enriched primary L1{sub 2} precipitates form on solidification. • Secondary L1{sub 2} precipitates form on aging, and show improved coarsening resistance. • Nb and Ta are enriched at the secondary nanoprecipitate/matrix interface. • Micro-additions of Nb and Ta have similar effects as V, previously studied. - Abstract: A dilute Al-0.07Zr-0.02Sc-0.005Er-0.06Si (at.%) alloy was microalloyed with 0.08 at.% Nb or Ta. Atom-probe tomography reveals that, upon aging, Nb and Ta partition to the coherent L1{sub 2}-Al{sub 3}(Zr,Sc,Er) nanoprecipitates (with average concentrations of 0.2 and 0.08 at.%, respectively),more »« less

Impact of microstructural stability on the creep behavior of cast Al–Cu alloys

Journal Article Milligan, Brian K. ; Roy, Shibayan ; Hawkins, Charles S. ; ... - Materials Science and Engineering. A, Structural Materials: Properties, Microstructure and Processing

Creep behavior of three cast Al–Cu alloys at 300 °C was studied by measuring their steady state creep rates as a function of stress. Microalloying additions in two alloys stabilized the θ' (Al₂Cu) precipitates to 300 °C, which allowed grain boundary-controlled creep deformation to dominate at low stresses in these alloys. In contrast, the instability of the microstructure at 300 °C in a conventional Al–Cu 206 alloy led to the majority of θ' precipitates transform to the θ phase. The 206 alloy displayed diminished resistance to dislocation motion and a dislocation creep mechanism dominated from the lowest stresses. A modifiedmore »« less

Progression of creep deformation from grain boundaries to grain interior in Al-Cu-Mn-Zr alloys

Journal Article Rakhmonov, Jovid U. ; Milligan, Brian K. ; Bahl, Sumit ; ... - Acta Materialia

Creep mechanisms are studied in θ'-Al₂Cu-strengthened Al-Cu-Mn-Zr alloys at 300 and 350°C for (i) ACMZ, a base alloy without further alloying elements and (ii) RR350, a commercial alloy with additions of Ni and Co forming distinct grain-boundary precipitates. At high stresses, creep is dominated by dislocations bypassing θ' precipitates within grains via the Orowan mechanism, as evidenced by (i) very high stress exponent (n~20-25) and (ii) α-Al and θ' lattice strains (measured via in-situ neutron diffraction) evolving during creep in a manner consistent with load transfer from the plastically-deforming α-Al matrix to elastically-deforming θ' precipitates. At intermediate stresses, both alloysmore »« less

Dislocation-θ' (Al2Cu) interactions during creep deformation of an Al-Cu alloy

Journal Article Milligan, Brian ; Ma, Dong ; Allard, Lawrence ; ... - Scripta Materialia

While precipitate-dislocation interactions are well-understood for Al-Cu alloys in tension, creep behavior has seen far less study. New, thermally-stabilized Al-Cu alloys have θ' (Al₂Cu) as strengthening precipitates that remain stable up to 300 °C (~60% of the melting temperature) and higher, where creep becomes essential to the mechanical behavior. This investigation identifies the precipitate-dislocation interactions in such an Al-Cu alloy using in-situ neutron diffraction and scanning transmission electron microscopy. Significant load transfer to the θ' precipitates occurs, which can be attributed to dislocation loops on the interfaces of θ' and the Al matrix. Thus, Orowan looping is identified to bemore »« less

Mechanisms for stabilizing θ'(Al₂Cu) precipitates at elevated temperatures investigated with phase field modeling

Journal Article Shower, Patrick T. ; Morris, James ; Shin, Dongwon ; ... - Materialia

While most Al–Cu and Al–Si–Cu alloys strengthened by the metastable θ' phase exhibit extensive microstructural degradation above 200 °C, recent experimental work has demonstrated that θ' precipitates can be stabilized to 350 °C by microalloying additions of Mn and Zr, resulting in improved mechanical properties at elevated temperatures. Here, the present work utilizes phase field modeling to study the relationship between microalloying solute elements and the coarsening resistance of θ'. Simulations are designed to parse out the relative influence of various stabilization mechanisms on microstructural evolution of θ' precipitates at elevated temperatures. Specifically, a ternary alloying element is added tomore »« less
