The present invention provides a combined heating system made by combining a local heating system with a central heating system.

In another example, the local heating is brazing.

The local heating causes the martensitic material to be transformed into austenitic material.

Each test includes locally heating a region of a part, wherein the local heating results in the formation of a thermal field in the part, and assessing a dimension of the thermal field.

The local heating is provided by a device having high luminous intensity.
