Solidification of metals

The term solidification indicates the conversion of material from the state of liquid to the state of solid. The solid-state is more compact and rigid than liquid, and the solidification indicates the transformation of material from a random state to a more compact and crystalline form. The point at which dendrite formation in liquid starts taking place is referred to as the solidification point.

3 Copper Unit Cell Uniqueness Here's a weird way to describe the structure of copper: Cu falls into the tetragonal crystal system with a = 0.256 nm, c = 0.362 nm = a√√2, and atoms located at 000 and. Its density is 8.94 g/cc at room temperature. (a) Draw a few adjacent units cells of the structure as described in this "weird" way. You should be able to see that there is a much more convenient way to describe the structure. What is it? (The point I wish to make is that there are many different unit cells that can be used to describe any given crystal, so we usually choose the one that is easiest to visualize.) (b) Calculate the radius of a copper atom using the above information. (c) Calculate the lattice parameter of the "better" unit cell of Cu.

9. Consider a metal rod, whose grain size can be adjusted by different processing techniques. The graph below shows how the yield stress changes with grain size d; the x-axis is logarithmic. The curve reaches a limiting value of 60 MPa as indicated by the horizontal dashed line on the y-axis, for very large grain sizes. Also, you are given the information that at d = 25 microns (vertical dashed line), the yield stress is 100 MPa. Using this information, what will be the yield stress at d = 5 microns? Select the closest numerical value. Use the Hall-Petch relation in working out your answer.
