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 ...

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 top ...

To achieve this, the steel must be quenched at a rate sufficiently rapid to avoid the decomposition of austenite during cooling to such products as ferrite, pearlite and bainite. The effectiveness of ...
