TL;DR: It is shown that oxygen can take the form of ordered oxygen complexes, a state in between oxide particles and frequently occurring random interstitials, which lead to unprecedented enhancement in both strength and ductility in compositionally complex solid solutions, the so-called high-entropy alloys (HEAs).

TL;DR: A counterintuitive strategy for the design of ultrastrong steel alloys by high-density nanoprecipitation with minimal lattice misfit, which enables a substantial reduction in cost compared to conventional maraging steels owing to the replacement of the essential but high-cost alloying elements cobalt and titanium with inexpensive and lightweight aluminium.

TL;DR: In this paper, the authors present a detailed overview of the field ion microscopy (FIM) and its application in the field of materials science and engineering, as well as an analysis of the image in a pure material.

TL;DR: In this paper, a tomographic atom probe (TAP) in which the atoms are field evaporated by means of femtosecond laser pulses has been designed, and the performance of the laser TAP is described and illustrated through the investigation of metals, oxides, and silicon materials.

TL;DR: A novel strategy for designing a new class of HEAs incorporating the additional interstitial element carbon results in joint activation of twinning- and transformation-induced plasticity (TWIP and TRIP) by tuning the matrix phase's instability in a metastable TRIP-assisted dual-phase HEA.
