2. When the eutectic interlamellar spacing reaches minimum value, the concentration of liquid in front of -phase is: A. Much greater than in front of -phase B. Much smaller than in front of -phase C. The same D. All of the above answers failed. 3. The picture below shows that: A. The smaller eutectic interlamellar spacing is, the smaller constitutional undercooling is B. The smaller eutectic interlamellar spacing is, the greater constitutional undercooling is C. In the case of eutectic solidification the constitutional undercooling do not depend on the interlamellar spacing D. All of the above answers failed 4. in the figure below, one can say that eutectics will grow at highest temperature(smallest undercooling) when: A. Tc=max,Tr=min B. Tc=minx,Tr=max C. Tc=max,Tr=max D. Tc=min,Tr=min 6. The picture below shows that the anomalous eutectics grows with the interlamellar spacing . A. b C. b D. e
