Welding When materials are joined by a welding process they are locally melted, re-solidify, and cool down to room temperature. The joining of two steel plates (pearlite) by welding is shown in the ...

By heating at this temperature pearlite, which is the lowest energy arrangement of steel, gets converted to ferrite and cementite. The graphite content of steel assumes a spheroidal shape after ...

"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 ...

Changing the carbon content of the alloy changes the microstructure of the pearlite and hence the mechanical properties of the alloy. The vertical alloy composition line on the partial phase diagram ...
