If the heating does not go all the way through then the center would not get to liquidus.

It sounds like he is making a thin layer or martensite, over layer of bainite.

But that would not explain why it would be harder than martensite. Unless they are confusing fracture toughness with hardness. I'd like to see the microstructure!

Confusing fracture toughness with hardness,that sounds more like it,invented a heat-treatment is like new math.

Go to the link and read the rest of the story. There is martensite, bainite, austinite and carbides all in the structure.................

Heating the sheet by running an electric current through it would cause the sheet to heat fairly evenly.
