At the eutectic composition, an alloy can solidify at a constant temperature. for effective dispersion strengthening, the dispersed phase should be needle-like, as opposed to round intermetallic compounds are usually hard and brittle. for effective dispersion strengthening, the dispersed phase should be continuous. stoichiometric intermetallic compounds exist over a range of compositions. faster solidification results in smaller interlamellar spacing

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.

If y gets smaller as x gets bigger and y have an relationship?
