Compact MgB2 bulks as superconductor were successfully prepared by rapid hot pressing process in high-purity flowing Ar protective atmosphere.

Thermoelectric properties of rapid hot-pressing N-type (Bi_2Te_3)_(0.9)(Ag_xBi_(2-x)Se_3)_(0.1) synthesized from doping Bi_2Te_3 nanocrystals

In the present study, bulk nanostructured WC-Co cermets were prepared by high energy ball milling and rapid hot-pressing; the physical and mechanical properties as well as microstructure of the sintered bulk materials were also measured.

The polycrystalline samples for measurement, with relative densities all above 90%, were prepared by rapid hot-pressing process.

For a kind of low carbon micro-alloyed steel,a thermal simulation test was conducted with samples of F+B+P microstructure and the effects of its cold deformation at room temperature on the distribution,size and composition of precipitates were investigated via a technological process for rapid heating and short holding time.

During the rapid heating for limestone calcination,a new platinum-membrane reactor(PMR),which accurately weighs the sample and acquires temperature of particles,was used.

Based on studying the phase diagram of the Ti-Al binary system, the microstructure types and continuous cooling transformations of the TiAl-based alloys, and the heat treatment practices and effects, a new rapid heating cyclic heat treatment technology with the characteristics of rapid heating, holding in single α phase region, short holding time and relatively slow cooling was proposed.
