The aim of the work was to produce laminated structures consisting of Ti-6Al-4V alloy and AA2519 plates and to investigate their microstructure and mechanical properties with anemphasis on the role of an additional AA1050 interlayer. Explosive welding was ...
Ferritic-martensitic Oxide Dispersion Strengthened (ODS) steels are potential materials for fuel pin cladding in Sodium Fast Reactor (SFR) and their optimisation is essential for future industrial applications. In this paper, a feasibility study concerning ...
High Entropy Alloys (HEAs) are a new class of random alloys having impressive strength and toughness. Here, a mechanistic, parameter-free, and predictive theory for the temperature-, composition-, and strain-rate-dependence of the plastic yield strength of ...
The representative characterization of the tensile behavior of strain hardening Ultra High Performance Fiber Reinforced Cementitious Composite (UHPFRC) remains a challenge. Currently, the uniaxial methods (direct tensile test and 4-point bending test) are ...
The detrimental effects of the H on the mechanical properties of the metals are known for more than a century. One of the most important degradation mechanisms is H embrittlement (HE). In this thesis, we examined a few famous proposed mechanisms in the fie ...
Atomistic simulations of bicrystal samples containing a grain boundary are used to examine the effect of hydrogen atoms on the nucleation of intergranular cracks in Ni. Specifically, the theoretical strength is obtained by rigid separation of the two cryst ...
Strain Hardening Ultra High Performance Fibre Reinforced Concrete (SH-UHPFRC), has a high tensile strength (over 10 MPa) and exhibit significant strain hardening (several ‰) under tensile loads. These appealing features make it a suitable material for impr ...
The application on existing Reinforced Concrete (RC) slabs of cast-on site Ultra-High Performance Fiber Reinforced cement-based Composite UHPFRC) layers is a very efficient reinforcement technique, currently spreading. For the design of these tensile reinf ...
A microscopic three-point bending test that measures the strength of faceted particles of high aspect ratio is developed and used to probe individual coarsened plate-like silicon particles extracted from the eutectic Al-12.6%Si alloy. Focused ion beam mill ...
An oxide dispersion strengthened ODS ferritic steel has been produced by mechanical alloying of Fe–14Cr–2W–0.2Ti (wt.%) prealloyed powder with 0.55 (wt.%) Fe2Y intermetallic particles and consolidated by hot isostatic pressing. The microstructure after the ...
