Engineers can reduce rail expansion risk by using heat-resistant materials, such as hypereutectoid rail steel and martensite rail steel, adjusting track design and ensuring timely repairs.

For the hypereutectoid composition shown by the vertical green bar the material enters the two phase austenite + cementite zone prior to cooling through the eutectoid temperature. While it cools ...

"Essentials of Heat Treatment" provides a through introduction to steel heat treatment, including a discussion of how heat and carbon content impact a steel's microstructure. This class also describes ...
