3D ChemiSTEMTM Tomography of Nano-scale Precipitates in High Entropy Alloys
نویسندگان
چکیده
Electron tomography is a three-dimensional technique well suited for characterizing fine-scale microstructural features on the order of 10-100 nm. Typically performed in a transmission electron microscope (TEM), it relies on successive image acquisition at multiple sample tilts. Images may be formed through various techniques including conventional and scanning transmission electron microscopy (CTEM and STEM), energy-filtered TEM (EFTEM), and energy dispersive x-ray spectroscopy (EDS). The variety of available image formation mechanisms has defined electron tomography as a robust fine-scale characterization tool.

HAADF-STEM and Super-XTM XEDS Tomography of Complex Nano-scale Precipitates in a High Entropy Alloy, AlMo0.5NbTa0.5TiZr
High entropy alloys (HEAs) are a relatively new class of materials garnering a great deal of attention due to their remarkable balance of properties, including high strength, toughness, ductility, and corrosion resistance. In contrast to conventional alloy systems, HEAs are based on 4 or more principal elements with near equimolar concentrations and tend to have simple microstructures due to th...

Creating and maintaining precipitates coherent with the host matrix, under service conditions is one of the most effective approaches for successful development of alloys for high temperature applications; prominent examples include Ni- and Co-based superalloys and Al alloys. While ferritic alloys are among the most important structural engineering alloys in our society, no reliable coherent pr...
متن کاملFerritic Alloys with Extreme Creep Resistance via Coherent Hierarchical Precipitates
There have been numerous efforts to develop creep-resistant materials strengthened by incoherent particles at high temperatures and stresses in response to future energy needs for steam turbines in thermal-power plants. However, the microstructural instability of the incoherent-particle-strengthened ferritic steels limits their application to temperatures below 900 K. Here, we report a novel fe...

The precipitation hardening behavior of an Al-0.08Zr-0.014Sc-0.008Er-0.10Si (at.%) alloy was investigated utilizing microhardness, electrical conductivity, atom-probe tomography (APT), and compressive creepmeasurements. This new composition, with a Sc:Zr atomic ratio of less than 1:5 represents a significant reduction of the alloy's cost when compared to the more usual Al-0.06Sc-0.02Zr based al...
متن کاملDevelopment of a Refractory High Entropy Superalloy
Microstructure, phase composition and mechanical properties of a refractory high entropy superalloy, AlMo0.5NbTa0.5TiZr, are reported in this work. The alloy consists of a nano-scale mixture of two phases produced by the decomposition from a high temperature body-centered cubic (BCC) phase. The first phase is present in the form of cuboidal-shaped nano-precipitates aligned in rows along <100>-t...
