Quiz - eutectic alloys question 4 of 4
Q4: the yield strength of a eutectic microstructure will be:

1 - lower in some directions because dislocations all exist in the same orientation

2 - proportional to the amount of the two phases and their respective yield stresses.

higher than answer 2 above

lower than answer 2 above
