in Mg alloys may exist in the form of second-phase particles and precipitate in grains or grain boundaries, substantially enhancing mechanical properties through second-phase strengthening.
Sintering density of PM steels depends on pressing load, particle size, added alloying elements
and sintering temperature and time.
The present work dealt with the investigation of the influence of alloying elements
in Zn-Al alloy on thermal and mechanical properties.
The mechanisms were identified to produce nanostructures from the melted liquid by taking advantage of the rapid thermal cycle and the diffusion of alloying elements
, as well as the heterogeneous nucleation generated by the HCPEB process.
It points to General Electric's research program to improve the use of rhenium, an important alloying element
in high-temperature turbines, by developing low-rhenium alloys and recycling existing supplies.
But for this purpose we must have exact value of alloying element
& level of impurities in respective master alloy.
During the corrosion process, the ratios of iron and alloying elements
may change, and the amount of oxygen in the metal sample increases.
The product is an alpha/beta titanium alloy whose alloying elements
produce a material that can be hot or cold rolled to produce sheet with strength comparable to conventional pack-rolled titanium 6-4 sheet, but with improved formability.
To optimise the melting process and pro-duce ingots with a guaranteed chemical com-position, and also minimise the losses of the alloying elements
in EBM of large ingots of creep-resisting titanium alloys, the technological parameters of melting for ingots with a diameter of 840 mm were determined by mathematical calculations (3).
(3) The different microstructure due to different alloying elements
is very likely to affect the mechanical behavior in the repeated high strain rate shock load.
Three electrodes were designed in the vacuum chamber: one anode and two negatively charged members, the cathode where the work piece was located, and the source electrode where the desired alloying elements
Following a brief historical background, the book more or less follows the sequence of the production process, offering chapters on metallurgy and alloy compositions; manufacture and characteristics of stainless steel powders; compacting and shaping; sintering and corrosion resistance; alloying elements
, optimal sintering, and surface modification in PM stainless steels; mechanical properties; magnetic and physical properties; corrosion testing and performance; secondary operations; and automotive and other applications.
It is now possible to buy an XRF (X-ray fluorescence) analyzer, which safely shoots X-rays into the metal being tested and, from the returning signal, determines the alloying elements
Built-up edge is especially common on stainless steels and high-temp alloys in which the material's alloying elements
are designed to provide resistance to corrosion and/or heat.
