Answer:
- TRUE
- FALSE
- TRUE
- FALSE
- FALSE
- TRUE
Explanation:
- At the eutectic composition, an alloy can solidify at a constant temperature : TRUE . this is because at eutectic composition the type of reaction that takes place there is invariant reaction in its thermal equilibrium
- For effective dispersion strengthening, the dispersed phase should be needle-like, as opposed to round : FALSE. because the rounded shape will not cause a crack.
- Intermetallic compounds are usually hard and brittle : TRUE. because Intermetallic compounds prevents dislocation movements and this makes them brittle and hard
- For the effective dispersion and strengthening, the dispersed phase should be continuous : FALSE. this is because the dispersed precipitate must be small and not continuous
- Stoichiometric intermetallic compounds exist over a range of compositions : FALSE
- Faster solidification results in smaller interlamellar spacing : TRUE
