On the Ettringite Form of Sulfate Attack: Part 2. The Expansive Mechanism of Concrete Caused by Seco
In part 1 of this two-part series, the formation mechanism of secondary ettringite has been discussed. In this part, the expansive mechanisms of secondary ettri
A self-made directional solidification setup was used to prepare high purity aluminum ingots of 100mm in diameter. The morphology of the growth interface was de
This work mainly investigated the influences of some factors, such as, synthesis methods, pre cursor alternatives, and vacuum heat-treating process, etc, on the
Creep behavior and microstructure evolution of directionally solidified superalloy IC10 at high temp
The creep behavior of directionally solidified (DS) superalloy IC10 was investigated under 192 MPa and 218 MPa at 980 ℃. Under the testing conditions, the mark
The main object of the present research is to make a quantitative evaluation on the microstructure of carbon materials in terms of microcrystal. The digitized i
To investigate the treating parameters influence on the surface roughness of the MAO ceramic coating on AZ91D, experiments were implemented in the alkaline elec
Al2O3/TiAl composites were fabricated by PAXD (pressure-assisted exothermic dispersion) method. The effects of Nb2O5 content on the microstructure and mechanica
Through the addition of rare earth oxides into the coating of electrodes, the high temperature oxidation and sulphidation resistance of weld metal were studied.
Effect of cooling rate on both microstructure and room temperature compressive performance of the AZ91 magnesium alloy was investigated. The experimental result
Honeycomb-like superstructures consisting of ZnS nanosheets with uniform thickness of about 20nm and lateral dimension of several micrometers were built up from
