Do you ever wonder about whether what you know is right? Most of us don’t, unless we run into something that forces us to re-evaluate things.

Sometimes, evaluation of fracture surfaces in the scanning electron microscope reveals features that do not easily fall into any of the classical crack categories.

Some people today have trouble telling the difference between science, technology and magic.

Figure 2 Figure 2 shows one of the most classical cleavage, or transgranular cracks, that I have ever found in a broken part. The red arrows highlight parallel sets of

Most of the failure analysis we have been talking about on this blog so far is about fractography and, specifically, about fractography that relates to the macro scale

Now, here is where the idea of case hardening comes in.

If, for now, we look at the “classical worst case,” or the outer fiber stress, y is 5.

“Everyone knows” that heat treating steels with a quench-and-temper process can make them stronger.

Before closing our discussion from last week, I will share some examples to illustrate the differences between normal ambient-temperature “corrosion-assisted fatigue” and “boiler-lingo corrosion fatigue.”
