Yanfei Gao, in Intermetallics, 2018 3 Fractographic characteristics Visually examining the fracture surfaces of failed HEAs is a straightforward means to study their fracture modes, thereby gaining insights on microscopic deformation...
Microstructure and mechanical properties of the CrMnFeCoNi highentropy alloy. (A) Fully recrystallized microstructure with an equiaxed grain structure and grain size of ~6 mm; the composition is approximately equiatomic, and the alloy is single-phase, as shown from the EDX spectroscopy and XRD inset...
To comprehensively understand the fracture mechanisms, material properties, root causes of failure, and the subsequent optimization of alloys, a detailed analysis of the internal fracture process and the morphological traits of the fracture surface is imperative. Traditional analysis of fracture surfaces ...
The features of cavitation and fracture did not differ much from an earlier study on a pseudo-single phase copper alloy, although copper alloys usually fail non-ideally, i.e., a large area of cross-section is present at fracture. This is a preview of subscription content, log in via an ...
Local mechanical properties of dissimilar metal TIG welded joints of CoCrFeMnNi high entropy alloy and AISI 304 austenitic steel Multiple principal element alloys encompass the well-known high entropy alloys (HEA). The alloy system represents a new class of materials consisting of at... R Michael...
