Indentation size effect, geometrically necessary dislocations and pile-up effects in hardness testing of irradiated nickel
TL;DR: In this paper, the Nix-Gao model was applied to determine the increase in the bulk yield strength arising from irradiation induced defects, which agreed well with the predicted increase in yield strength from the Bacon-Kocks-Scattergood (BKS) obstacle hardening model, using a superposition of SFT, glissile perfect loops and sessile Frank loops.

Radiation tolerance of commercial and advanced alloys for core internals: a comprehensive microstructural characterization
TL;DR: In this paper, 13 austenitic stainless steels, nickel-base alloys, and ferritic alloys were irradiated using 2'MeV protons at 360'°C to a damage level of 2.5 displacements per atom (dpa).

A threshold density of helium bubbles induces a ductile-to-brittle transition at a grain boundary in nickel
TL;DR: In this article, the authors describe molecular dynamics simulations of fracture along a grain boundary (GB) in nickel (Ni) decorated with helium (He)-filled bubbles and find that the quantity governing embrittlement of the GB is its areal coverage by He bubbles.

Defect formation in AlN after irradiation with He2+ ions
TL;DR: In this paper, the defect formation processes, radiation resistance, and changes in the conductive and insulating characteristics of AlN ceramics under irradiation with 40 keV He2+ ions were investigated.
Journal ArticleDOI
Influence of He-ion irradiation of ceramic AlN
TL;DR: In this article, the effect of irradiation of low-energy helium ions on structural properties and morphology of AlN polycrystalline ceramics was studied. But the results were limited to two types of types: I and II.

Computational modeling of the forward and reverse problems in instrumented sharp indentation
TL;DR: In this article, a comprehensive computational study was undertaken to identify the extent to which elasto-plastic properties of ductile materials could be determined from instrumented sharp indentation and to quantify the sensitivity of such extracted properties to variations in the measured indentation data.

On the use of SRIM for computing radiation damage exposure
R. E. Stoller,Mychailo B. Toloczko,Gary S. Was,Alicia G. Certain,Shyam Dwaraknath,Frank A. Garner +5 more
TL;DR: The SRIM (formerly TRIM) Monte Carlo simulation code is widely used to compute a number of parameters relevant to ion beam implantation and ion beam processing of materials as discussed by the authors.
Strength of metals and alloys
TL;DR: The paper as discussed by the authors presents the papers given at a conference on the mechanical properties of metals and alloys, including hardening, anisotropy and texture, phase transformations, creep resistance, plasticity, deformations, microstructure, fracture properties, fatigue, wear resistance, temperature effects, stress analysis, and recrystallization.
