Which of the following processes will tend to strengthen a typical pure metal ? Assume that we are comparing the stress-strain response of the original metal to the stress-strain responses of the room-temperature altered metals after these separate processes have been conducted. Select all that apply. Cold-working the pure metal. Hot-working the pure metal. Adding solute to form a solid solution. Precipitation of a secondary phase Annealing the pure metal. Melting then casting the pure metalIncreasing the dislocation density (dislocations count per unit volume) Decreasing the grain density (grain count per unit volume Increasing the average grain size

answer: a

a is the answer

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
