Engineering Fundamentals: An Introduction to Engineering, 4th ed.c

4.19. In an annealing process — a process wherein materi-

als such as glass and metal are heated to high temper-

atures and then cooled slowly to toughen them — thin

steel plates are heated to temperatures of 900°C and

then cooled in an environment with temperature of

35°C. The results of an annealing process for a thin

plate is shown below. Plot the data using engineering

paper incorporating the ideas discussed in this

chapter.
