Mathematical Modeling of Heat Transfer for Steel Continuous Casting Process

     Heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. A heat transfer and solidification model is described for the continuous casting of steel slabs. The model has been established on the basis of the technical conditions of the slab caster in the con...

Effect of Heat Treatment on Mechanical Properties of H13 Steel

This paper reports results of in-house experimentation on heat treatment and mechanical testing of H13 tool steel. Heat treatment strategy practiced by the industry is described in detail. Effect of various types of heat treatment on fracture toughness, hardness and other mechanical properties is also analyzed. It was found that toughness (expressed in terms of plane-strain fracture toughness K...

Prediction of Heat Treatment Distortion of Cast Steel C-rings

Navy C-Ring test parts were made of AISI 1022, 4320, 8625, and CF8M steels and heat treated in a designed experiment to evaluate the commercial heat treatment distortion simulation software DANTE. The parts were machined and then measured with a CMM for original dimensions. The parts were then heated and subsequently quenched in two different immersion orientations in agitated water. Temperatur...

Overview of theMechanisms of Failure in Heat Treated Steel Components

Design deficiencies are a common source of component failure. Examples include the presence of a sharp notch in regions of high stress or a fillet radii that is too sharp. Using a component design for a new application can also lead to unanticipated failures. Higher stresses or unanticipated service conditions can cause unforeseen failure because of complex or increased stress fields. Stress co...
