Why do we use heat treatment in materials?

Explain the mechanism of the corrosion fatigue and thermal fatigue, how to prevent/protect from your design?

What is a solid solution? In general, what is its implication on the mechanical behavior of metals (i.e., increase or decrease in strength)?

Calculate the percent error for the heat capacity of steel given that the true value is 0.466 J/g ˚C

Select 3 principal driving forces for the development of mechanical properties during heat treatment. Group of answer choices:   Microstructure Changes Formation of Surface Oxide Cooling Rate Ambient Temperature Heating Rate Diffusion Rate Heating Method

The properties of some very ductile metals, such as certain low- carbon steels, change at low temperatures at their particular transition zone. How can this information help an engineer design machinery that will be operating in subzero temperatures?

A change in temperature can cause a member made of homogeneous isotropic material to change its length why?

Normally when the creep is considered in materials?
