One type of metal failure is known as “creep”. What is creep?
Exposure to high temperatures or stress can cause metal to elongated or stretch.
Exposure to high temperatures or stress can cause small cracks at joints which will slowly grow
Exposure to high temperature or stress can cause metal to turn brittle.
Exposure to high temperatures or stress can cause a slow shrinkage of meta
