Deformation damage during tension and compression were revealed using in-situ neutron diffraction for a high manganese steel: (1) When the tensile stress is increased, an indication of provided when 111 422 lattice strains along transverse direction give no more contraction or even expansion. This because that replacement slip twinning activities by crack propagation induces relaxation, which c...

This paper describes an improved microwave digestion procedure for steel samples of various kinds intended inductively coupled plasma atomic emission spectrometry, including low alloy steel, stainless alloyed tool and high-speed steel. Their resulting solutions were used the simultaneous quantification elements together with several light boron, aluminum, silicon, phosphorous. Conventional meth...

in this paper, the correlation between the surface rumpling and cracking phenomena with twinning mechanism during plastic deformation of hadfield steel has been investigated. the effect of stacking fault energy and the amount of strain are evaluated. the experimental samples with specific amounts of carbon, manganese and aluminum resulting in different stacking fault energies, were produced usi...

Metallic materials, especially steel, underpin transportation technologies. High-manganese twinning induced plasticity (TWIP) austenitic steels exhibit exceptional strength and ductility from twins, low-energy microstructural defects that form during plastic loading. Their high-strength could help light-weighting vehicles, hence cut carbon emissions. TWIP are however very sensitive to hydrogen ...

The article presents results of study possibility hardening high-manganese steel X120Mn12 by a deformation wave in the process strain (WSH). Features method is using shock waves for plastic deformation, which significantly expands technological capabilities formation hardened surface layer. dominant design and parameters treatment are established, have main influence on microstructure hardness ...

The manganese bath method for measuring the neutron emission rate of radionuclide sources requires corrections to be made for emitted neutrons which are not captured by manganese nuclei. The Monte Carlo particle transport code MCNP has been used to calculate the fractions of neutrons that escape from the boundaries of the tank, that are captured by the steel cavity in which the source is housed...

Microstructural banding is defined as alternating layers of two different microstructures in steel, often ferrite and pearlite. It is caused by fluctuations in the concentration of alloying elements, primarily manganese, due to microsegregation introduced during solidification. In this thesis, a model is presented to simulate banding using phase transformation kinetics theory. An existing progr...

Manganese-deficient individuals have decreased manganese elimination. This observation has prompted suggestions that relative manganese deficiency may increase the risk for manganese neurotoxicity following inhalation exposure. The objective of this study was to determine whether dietary manganese intake influences the pharmacokinetics of inhaled manganese tetroxide (Mn3O4). Postnatal day (PND)...
