Precipitation hardening, also called age or particle hardening, is a heat treatment process that helps make metals stronger. The process does this by producing uniformly dispersed particles within a metal's grain structure that help hinder motion and thereby strengthen it particularly if the metal is malleable.

Precipitation hardening relies on changes in solid solubility with temperature to produce fine particles of an impurity phase, which impede the movement of dislocations, or defects in a crystal's lattice. Since dislocations are often the dominant carriers of plasticity, this serves to harden the material.

The Precipitation Hardening Process as follows:

1.Solution Treatment: You heat the metal to a high temperature and treat it with a solution.

2.Quenching: Next, you quickly cool down the solution-soaked metal.

3.Aging: Finally, you heat the same metal to a medium temperature and cool it quickly again.

Assume you have a metal alloy - an aluminum alloy for example - that has been welded and then heat treated in a way that leaves you uncertain as to the microstructure. Since the component is to be used for a critical application, you want to be sure of both the structure and mechanical properties. You want to create a single phase structure so that you can "start over" with a new heat treat cycle to more exactly and carefully...

In order to study the quality of parts, a batch of 100 parts was checked at the enterprise. The results are presented in the following table: Groups of parts by weight, g 40-50 50-60 60-70 70-80 80-90 90-100 100-110 110-120 Total Number of parts 2 4 11 19 21 25 10 8 100 Determine the mean, variance, mode, median, 1st and 3rd quartiles, coefficient of variation, plot a histogram, find asymmetry and kurtosis. Calculated indicators indicate in the figure.

Bowling balls can be made from a variety of substances and are required to have a circumference of roughly 27.4 inches. The construction of the ball typically consists of a high density core surrounded by a lower density shell. Suppose a bowling ball floats in water with half of its volume submerged. If the specific gravity of the shell is 0.350 and the specific gravity of the core is 0.800, calculate the thickness of the shell.
