Abstract:
This study explores the effects of ultrafast heating on AISI 304 austenitic stainless steel. The research shows that ultrafast heating can lead to fine-grained mixed microstructures in steel, making it a potential alternative for modifying microstructure in stainless steel. The study demonstrates that a minimum temperature of 980 °C is required to achieve a fully recrystallized microstructure. The results also suggest that a lower temperature can result in a finer recrystallized grain size compared to higher temperature results. The study provides valuable insights into the impact of ultrafast

Microstructures of metal micro parts after microforming at elevated temperatures must be evaluated due to mechanical properties depend on average grain size. In this work, the effects of specimen diameter on the microstructure and microhardness of a hot-extruded AZ31B magnesium alloy were studied. Obvious size effect on microstructure and microhardness of the alloy could be observed. The size effects could be explained by strain distribution and dislocation density differences between the two kinds of specimens.

Basic research considering the minimum achievable grain size of severe plastic deformation (SPD) materials is often performed with high purity metals.

The microstructure of SPD nickel was systematically investigated using different purities ranging from 99.79 wt% up to 99.99 wt%.

It is by now well-known that micron-sized metallic crystals exhibit a smaller-being-stronger size effect: the yield strength σvaries with specimen size D approximately as a power law σ~D^(-m)_, and the exponent m has been found to vary within a range of ~0.3 to ~1.0 for different metals. However, little is known about why such a power law comes into play, and what determines the actual value of the exponent m involved.

Abstract:
Abstract Carbide free bainitic microstructures can be developed via different thermal processing routes, and the details affect the scale and morphology of the microstructural constituents. In this study, bainitic microstructures are formed by either a controlled cooling process or an austempering process to evaluate the relationship between microstructure and mechanical properties in a 0.2C - 2Mn - 1.5Si - 0.8Cr steel containing small amounts of Nb, Ti, B, and N, and the results are compared to a 4140 steel processed via quenching and tempering. The resulting microstructures are characterized

Abstract:
Abstract Three low alloyed carbon steels were given different heat treatment before testing in a corrosion flow loop at 80°C. Both the general corrosion rate and the susceptibility to form localized attack were significantly affected by the tempering temperature and the size and distribution of the carbides. Two of the steels contained small amount of chromium and it was seen that the presence of chromium improved the persistency of the corrosion film for all the heat treated samples.

Abstract:
Abstract Production of oil and gas in the Brazilian pre-salt faces several technical challenges and one of the major concerns is the presence of CO2 in high concentrations. Enhanced oil recovery (EOR) using CO2 might be a great opportunity to increase productivity and address environmental issues avoiding the release of CO2 to the atmosphere. The EOR working pressure can reach up to 500 bars and in case of sudden depressurization local temperature can decrease down to -60°C or lower increasing the possibility of catastrophic failure. The aim of this work is to evaluate fracture toughness of tw

Abstract:
Abstract The purpose of this research was to investigate the influence of microstructure of Armco iron on hydrogen trapping by analyzing the trapping ability of grain boundaries and dislocations. Hydrogen traps were introduced into the material by systematically subjecting it to various grades of heat treatment and mechanical deformation. By combining different treatment steps (annealing at different temperatures, cold rolling at various deformation degrees, severe plastic deformation), a wide range of different grain sizes and dislocation densities was created.

Full text
Abstract:
In this paper an isotropic hardening elastoplastic constitutive model for structured soils is applied to the simulation of a standard CPTu test in a saturated soft structured clay. To allow for the extreme deformations experienced by the soil during the penetration process, the model is formulated in a fully geometric non-linear setting, based on: i) the multiplicative decomposition of the deformation gradient into an elastic and a plastic part; and, ii) on the existence of a free energy function to define the elastic behaviour of the soil. The model is equipped with two bonding-related intern

Abstract:
The dynamic state of the land surface presents challenges and opportunities for military and civil operations in extreme cold environments. In particular, the effects of snow and frozen ground on Soldier and vehicle mobility are hard to overstate. Current authoritative weather and land models are run at global scales (i.e., dx &gt; 10 km) and are of limited use at the Soldier scale (dx &lt; 100 m). Here, we describe several snow physics upgrades made to the Noah-Multiparameterization (Noah-MP) community land surface model (LSM). These upgrades include a blowing snow overlay to simulate the lat
