They were prepared through a milling process, compacted under different pressures (350, 450, 550 and 650 MPa) and sintered in air atmosphere at 1000 °C for 1 h.
After a single ECAP compaction process, the compacts possessed near 99% theoretical density and annealing treatment further increased the density and enhanced the bonding between chips.
Disintegration is a limiting factor in dissolution process of compact for low water soluble active ingredients.
Coal firms have disposed of this combination of solids and water in a few different ways: damming it in large ponds, depositing it in abandoned mines and using a dry filter-press process to compact it.
As a key enabler of high accuracy in this process, a compact desktop-size beam flexure-based nanopositioner was designed with millimeter range and nanometric motion quality.
In the process of compact city development, the limited availability of the land resources for green space (GS) would represent a major challenge for urban environments.
Using the similar compositions of the Ti-microalloyed high-strength steels produced by the thin-slab casting process of compact strip production (CSP), four thermo-mechanical control processes (TMCP) after the simulated thick-slab casting, i. e. the two hot rolling routes and the two cooling processes, were designed, aiming at achieving the same mechanical properties as the thin strip products.
In this paper, the process of compact polymer chains escaping from a small sphere to a large one in the view of thermodynamics is investigated in detail based on the pruned-enriched-Rosenbluth method (PERM), which is quite efficient for the three-dimensional polymers on the simple-cubic lattice.
At the initial stage of MAO process, the compact barrier layer of NdFeB magnets was formed through the deposition of the electrolyte, which was the critical procedure for the MAO treatment of NdFeB magnets and the biggest difference from the valve metals through the conventional anodizing.
During the pretreatment process the compact structure of lignocellulosic is disrupted and cellulose fiber is exposed.
