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.

The new-style low heat-inertia fast-heating furnace for metal sample is developed based on its special need.

The article studies the caking property of the coal-dust after rapid preheating.

It was found that the coking index of coals increased markedly by the rapid preheating.

In this paper,the super rapid heating hardening of 45 steel samples by means of condenser block pulse discharging is introduced.

8,1) by “rapid heating procedure” and investigated series of samples using XRD,SEM techniques.
