PT Journal AU FILIPEK, J TI MODELS OF TWO-ARMED LEVERS IN EQUILIBRIUM DIAGRAMS SO Trends in education PY 2014 BP 42 EP 45 VL 7 IS 1 DE two-armed lever; equilibrium diagrams; phase and structure. AB In the article is drawn two-armed lever system, which clearly show the equilibrium states of binary alloy at various temperatures. The systems are different for the phase, structural and comprehensive view. The accompanying animation shows the continuous and step changes during cooling of the alloy. ER
