Influence of the Quenching Rate on the Structure and Magnetic Properties of the Fe-Based Amorphous AlloyArchives of Metallurgy and Materials - Tập 61 Số 1 - Trang 439-444 - 2016
M. Nabiałek
This paper presents the results of investigations into the structure,
microstructure and magnetic properties of Fe61Co10Y8W1B20 amorphous alloy. The
alloy samples were in two physical forms: (1) plates of approximate thickness
0.5 mm (so-called bulk amorphous alloys) and (2) a ribbon of approximate
thickness 35 μm (so-called classic amorphous alloy). The investigations
comprised: X-ray diffractome... hiện toàn bộ
Ab Initio Study of Structure, Electronic and Magnetic Properties of YFe5 Phase Compound in the DFT FormalismArchives of Metallurgy and Materials - Tập 61 Số 1 - Trang 369-374 - 2016
K. Gruszka, M. Nabiałek, T. Noga
Paper presents results of studies on structural, electronic and magnetic
properties of YFe5 compound using density functional theory (DFT) approach. The
GGA functional with ultrasoft pseudopotentials were used as implemented in
Quantum Espresso software. The structure of YFe5 compound was examined in three
different states namely nonmagnetic, antiferromagnetic and ferromagnetic. Also
two antiferro... hiện toàn bộ
Manufacturing of Porous Al-Cr Preforms for Composite Reinforcing Using Microwave Activated Combustion SynthesisArchives of Metallurgy and Materials - Tập 59 Số 3 - Trang 1125-1127 - 2014
K. Naplocha, K. Granat
Abstract The combustion synthesis of porous skeletons (preforms) of
intermetallic Al–Cr compounds intended for metal matrix composite MMC
reinforcing was developed. Mixture of Al and Cr powders with granularity of −10,
−44, −74mm were cold isostatic pressed and next ignited and synthetized in a
microwave reactor under argon atmosphere (microwave-activated combustion
synthesis MACS). In order to ig... hiện toàn bộ
The Influence of Mo Content on Phase Transformation in Ti-Mo AlloysArchives of Metallurgy and Materials - Tập 62 Số 4 - Trang 2051-2056 - 2017

AbstractTitaniumβ-type alloys are a class of interesting biomaterials that can
exhibit a unique combination of mechanical as well as physicochemical and
biological properties. The aim of this study is to develop a titanium-molybdenum
alloys (Ti-x at % Mo,x= 15 and 23). These materials were prepared by the
combination of mechanical alloying and powder metallurgical process. The details
of the proce... hiện toàn bộ
Quasi-Static and Dynamic Tensile Properties of Ti-6Al-4V AlloyArchives of Metallurgy and Materials - Tập 58 Số 4 - Trang 1261-1265 - 2013

Abstract Ti-6Al-4V alloy is widely used, mainly in aircraft industry, due to its
low density, excellent corrosion/oxidation resistance and attractive mechanical
properties. This alloy has relatively low formability, so forming parts of
complex geometries out of this alloy requires precisely controlled
thermomechanical processing parameters. In industrial conditions Ti-6Al-4V alloy
is usually proce... hiện toàn bộ
Recent Developments on Discontinuous PrecipitationArchives of Metallurgy and Materials - Tập 62 Số 2 - Trang 955-968 - 2017
P. Ziȩba
AbstractThe discontinuous precipitation (DP) belongs to a group of diffusive
solid state phase transformations during which the formation of a new phase is
heterogeneous and limited to a migrating reaction front (RF). The use of
analytical electron microscopy provided reliable information that there is no
differences in the diffusion rate at the stationary grain boundary and moving RF
of DP reacti... hiện toàn bộ
Microgravimetric Studies of Selenium Electrodeposition Onto Different SubstratesArchives of Metallurgy and Materials - Tập 59 Số 3 - Trang 871-877 - 2014
Remigiusz Kowalik
Abstract The mechanism of selenium electrodeposition from sulfuric acid solution
on different substrates was studied with the electrochemical techniques. The
cyclic voltammetry was combined with the quartz crystal microbalance technique
to analyze selenium deposition process. The electrochemical reduction of
selenous acid on gold, silver and copper electrodes was investigated. It was
found that re... hiện toàn bộ
The Characterization Of Cast Fe-Cr-C AlloyArchives of Metallurgy and Materials - Tập 60 Số 2 - Trang 779-782 - 2015

AbstractThe paper presents the results of the characterization of alloy from
Fe-Cr-C (carbon content 0.79 wt.%) system including the microstructure, phase
analysis, morphology and hardness in as cast state. The chemical composition was
designed to create chromium-rich ferritic matrix with high volume fraction of
carbides in form of interdendritic eutectics. The research was carried out on
the cros... hiện toàn bộ
