Page 11.739.6The 1020 alloy does not harden or demonstrate good hardenability due to the low carbon content.Both the 4140 and 4340 develop greater surface hardness than the 1020 alloy due to the highercarbon content. The 4340 alloy which has a higher chrome content demonstrates a much betterthrough thickness hardenability than does the 4140 alloy.

This was the culminating project forstudents who had challenged the AP-B Physics course. Student teams were tasked withdesigning a boat made solely from cardboard and duct tape that would carry two students acrossa school swimming pool. Understanding concepts in structural design and buoyancy werecritical to this project. It provided faster response to student questions and certainly made for astronger learning environment in teacher’s classroom.

We allowed the students to retake the quiz as many times as they wanted until they got the score they were satisfied with. Most students ended up cycling through the entire pool of questions each week. While this did not force the students to read the entire chapter, at least it helped them read the parts of the book that we thought were the most important by our choice of question. Typical questions are listed below:! 1) To improve the lifetime of a part that experiences fatigue you can: A. Paint the surface B. Lower the mean
recrystallization process.Figure 3. The effect of annealing on the microstructure (a) cold work, (b) after recovery, (c) after recrystallization, (d) after grain growth.If the material is heated above the TR temperature grains will tend to grow in size. Diffusion ofatoms into the grain at high temperatures causes grain boundaries to move. Some grains grow atthe expense of others therefore reducing grain boundary energy. The driving force for graingrowth is the decrease in free energy associated with the grain boundary area at the expense ofincrease area of the grains. As grain growth continues its size is restricted by fine dispersion ofsecond phase particles in the microstructure.Engineering Design Consideration of Cold Work and Annealed

direction per time step (assuming particles have a 25% of jumping in each direction). (b) Depiction of Fick’s 1st law: blue numbers with arrows indicate the flux of particles through that blue dotted line.Fick’s 2nd law describes how concentration will change over time. Figure 3a retains the bluenumbers indicating flux from Figure 2b and adds green numbers indicating how many atoms willbe gained or lost at each x-position. The change in number of atoms is simply the sum of theatoms entering or leaving that x-position, i.e. the flux on either side. For example, at x=2, the fluxon the left is zero and the flux on the right is -1 (1 to the left). So, the number of atoms at x=2will increase by 1 at the next time step. At x=3, the number of atoms
