Sárgaréz és ónbronz ötvözetek termodinamikai átrendeződéseinek tanulmányozása DMTA mérőberendezéssel

The researcher work pushes the borders of the application of a high efficiency equipment, in the matter of metals. With this equipment, which already testified in the compound industry, a flasher query of some metalrelated technological parameters could be easily available. Towards the searching, we shaped different compound copper-alloy samples, in different grades, and accordingly we monitored the realignments. Following the shaping, the DMTA detected such microscopic transformations (as we expected), according to heating rate, whereby we could determine the specialities of the transformations. Taking into account the chemical compound of the samples, we distinguished tin-bronzes and brasses. Our main object was the monitoring of the recrystallization, and the investigation of the influential factors of this process, but other transitions were also regarded. Those measurements’ results, that the DMTA presented, had been compared with DSC and hardness analysis, whereby we try to conclude to the utility of DMTA, in matter of metal alloys.
