Low temperature diffusion bonding of stainless steel
Springer Science and Business Media LLC - Tập 63 - Trang 853-857 - 2011
Diffusion bonding of stainless steel (SS) has been attempted in temperature
range of 623–773 K using multiple inter-layers of nickel, copper and silver. The
intermediate layers were electro-deposited taking care to avoid oxidation at the
interfaces. The bonded area was examined for the formation of any intermetallic
compound through electron probe micro-analyzer (EPMA) and nano-indentation
techniq...
Study of Binary, Ternary, and Quaternary Basicity in Reduction of Saprolitic Nickel Ore
Springer Science and Business Media LLC - Tập 74 - Trang 3249-3263 - 2021
In the selective reduction process of lateritic nickel ore, the formation of the
liquidus phase could be obtained by increasing the temperature and additive,
resulting in an uneconomic process. Nevertheless, it could also be obtained by
modifying the ore basicity by adding low-cost fluxes, such as CaO, SiO2, MgO,
and Al2O3. In this work, the effect of three types of basicity (binary, ternary,
and ...
Thermal Properties, Microstructure and Microhardness of Cu–Al–Co Shape Memory Alloy System
Springer Science and Business Media LLC - Tập 67 - Trang 595-600 - 2014
In this study, the effects of Co content on the crystal structure,
transformation temperatures and microstructure of Cu–Al–Co shape memory alloy
system were investigated. It was found that Cu–Al–Co alloy system has also 18R
type martensitic structure, which is commonly observed in copper-based systems.
The transformation temperatures were found to be higher than 250 °C and they do
not show a linea...
Application of Back Propagation Neural Network Model for Predicting Flank Wear of Yttria Based Zirconia Toughened Alumina (ZTA) Ceramic Inserts
Springer Science and Business Media LLC - Tập 68 - Trang 783-789 - 2015
A back propagation neural network model has been adopted for the flank wear
prediction of zirconia toughened alumina (ZTA) insert in turning operation. The
experiments are performed on AISI 4340 steel using developed yttria based ZTA
inserts. These inserts are prepared through wet chemical co-precipitation route
followed by powder metallurgy process. Machining conditions such as cutting
speed, fee...
Effect of Quenching and Tempering Processes on Sharpness of Knives Made from 6Cr13 High-Carbon Martensitic Stainless Steel

Effect of Oxide Particles on Ferrite Phase Transformation in Low Carbon Micro-alloyed Steels
Springer Science and Business Media LLC - Tập 74 - Trang 3227-3240 - 2021
The mechanism of ferrite nucleation induced by different oxide particles was
studied in this article. The inclusion insertion experiment as a simulated
experiment was carried out using different oxide powders on a thermal simulator
under certain heat treatment conditions. The main results showed that the
chemical influences of oxide particles on ferrite nucleation are difficult to
occur under soli...
Dynamic Compression Deformation and Constitutive Model of Extruded Mg–1Zn–2Y Bar
Springer Science and Business Media LLC - Tập 74 - Trang 2967-2975 - 2021
The dynamic compression tests of Mg–1Zn–2Y (wt.%) alloy were carried out by a
split Hopkinson pressure bar (SHPB) device at room temperature and a strain rate
of 1524–2106 s−1. Based on the electron back-scattering diffraction test result,
it was found that with the increase in the strain rate, the proportion of
{10_12} 1tensile twinning-basal slip participating in the deformation first
increased ...
Mechanism of Interface Reactions Between Fe-2%Al Alloy and High-Silica Tundish Refractory
Springer Science and Business Media LLC - Tập 72 - Trang 591-602 - 2019
The reactions between a Fe-2%Al alloy and a high-silica tundish refractory were
investigated at 1550 °C in an alumina crucible using a high-frequency induction
furnace. The reaction between the dissolved aluminum in the molten alloy and the
oxidizing components in the refractory took place at the interface, generating a
MgO·Al2O3 spinel as the main product, which was confirmed by both experimental...
Challenges and Opportunities for Long Product Speciality Steels in India
Springer Science and Business Media LLC - Tập 66 - Trang 515-517 - 2013
Metallic and operating cost as well as specific energy consumption are the key
to long term viability of steel plants. Usha Martin achieved the highest
directly reduced iron (DRI) rotary kiln campaign life which is a good case study
for Indian steel makers who consume large quantities of DRI produced through the
rotary kiln route. The factors affecting rotary kiln life and how the kiln life
was ex...
