A numerical model was developed to simulate an induction tempering process, solving an electromagnetic thermal coupled problem. The temperature distribution inside an alloy steel work-piece was computed and the final hardness was predicted using...

After tempering of steel parts in the range of 260°C to 400°C there is a risk of

Tempered Martensite Embrittlement (TME). The common method for determining

embrittlement is the destructive impact test which is expensive and time...
