Design of Light-Weight High-Entropy Alloys
High-entropy alloys (HEAs) are a new class of solid-solution alloys that have attracted worldwide attention for their outstanding properties. Owing to the demand from transportation and defense industries, light-weight HEAs have also garnered widespread interest from scientists for use as potential structural materials. Great efforts have been made to study the phase-formation rules of HEAs to ...
متن کاملExperiments and Model for Serration Statistics in Low-Entropy, Medium-Entropy, and High-Entropy Alloys
High-entropy alloys (HEAs) are new alloys that contain five or more elements in roughly-equal proportion. We present new experiments and theory on the deformation behavior of HEAs under slow stretching (straining), and observe differences, compared to conventional alloys with fewer elements. For a specific range of temperatures and strain-rates, HEAs deform in a jerky way, with sudden slips tha...
متن کاملNear equiatomic FeCo alloys: constitution, mechanical and magnetic properties
Alloys based on the near-equiatomic FeCo offer exceptional magnetic properties. The equiatomic alloy was ‘invented’ in 1929, it offers a saturation hardly lower than that of the maximum obtained for Fe-0.35Co, with higher permeability and a lower coercivity than the latter. However, this alloy remained without industrial application, mainly because of its extreme brittleness. Only with the addi...
متن کاملPower-law creep in near-equiatomic nickel–titanium alloys
The compressive creep behavior of nickel-rich B2–NiTi (with 50–140 lm grain size) was studied over the stress range 3–11 MPa and the temperature range 950–1100 C. The stress exponent (n = 2.7) and activation energy (Q = 155 kJ mol ) are compared with a literature review of NiTi creep studies performed over lower temperature and/or higher stresses. Possible explanations for discrepancies between...
متن کاملThree Strategies for the Design of Advanced High-Entropy Alloys
High-entropy alloys (HEAs) have recently become a vibrant field of study in the metallic materials area. In the early years, the design of HEAs was more of an exploratory nature. The selection of compositions was somewhat arbitrary, and there was typically no specific goal to be achieved in the design. Very recently, however, the development of HEAs has gradually entered a different stage. Unli...
