These new heat treatments often involve the tempering or annealing of the steel to accomplish a partial or complete reversion from martensite to austenite. The influence of these reversion heat treatments on the product microstructure

Raphael B?melburg,Oliver Gassmannr predictions of macrosegregation based on these equations are compared with macrosegregation measured in experimental ingots..Agreement between calculations and experimental results is excellent. Experiments have been on model ESR ingots (65–105 mm diameter) of Sn-Pb and Al-Cu alloys; in addition,

The mathematical formulation of the problem is described in detail, while specific examples include induction stirring, electroslag welding, electric arc melting, and arc welding. It is shown that the calculated predictions of flow behavior in these operations correspond closely to the expe
