Abstract

Za dosego želenih fizikalnih in mehanskih lastnosti inženirskih materialov je ključnega pomena natančno spremljanje razvoja mikrostrukture pri izdelavi materialov. V prispevku je zbran pregled merilnih metod, s katerimi je mogoče kontrolirano spremljanje usmerjenega strjevanja. Predstavljene metode temeljijo na neporušnem in kontinuirnem ugotavljanju vrednosti vplivnih parametrov v bližini strjevalne fronte (▫$G_SF$▫ - temperaturni gradient na strjevalni fronti, ▫$V_SF$▫ - hitrost potovanja strjevanja fronte, ▫$\deltaT_SF$▫ -podhladitev strjevalne fronte, ugotavljanje oblike stjevalne fronte) med samim usmerjenim strjevanjem in jih je mogoče uporabiti v raziskovalni in industrijski praksi.

Secondary title: A review of measurement methods for in-situ monitoring of directionally solidified engineering materials
Secondary abstract: To achieve the required physical and mechanical properties of engineering materials, accurate monitoring of the microstructure evolution during the process of production is of crucial importance. This paper reviews some methods used for in-situ monitoring of the directional solidification process. Emphasis is given to the methods which allow nondestructive and online monitoring of the influence of parameters in the vicinity of the solidification front (▫$G_SF$▫ - temperature gradient on the solidification front, ▫$V_SF$▫ - velocity of the solidification front, ▫$\deltaT_SF$▫ - supercooling of the solidification front, determination of the interface shape) during the directional solidification process. The methods can be used in research and in industrial applications.
