The animation below shows the heat treatment simulation of an axle shaft using DANTE.
Part: 1 m long, 34.93 mm diameter axle shaft with a flange on one end and a 35-tooth spline on the other end.
Process: Inductor dwells at flange end for 9 seconds and then begins to move up the shaft at 12 mm/s for 1.5 seconds. The inductor slows to 8 mm/s and the spray begins at the flange. The inductor continues up the shaft, with the spray following, until the inductor is shut off as it nears the spline.
The animation below shows the heat treatment simulation of a large landing gear using DANTE.
Part: 3 m long landing gear made of 300M steel.
Process: The landing gear is lowered into an oil tank, after being heated in a pit furnace, at a rate of 4 m/s. The landing gear then sits, fully immersed, in the oil until the phase transformations have completed.
Residual stress, predicted from a DANTE heat treatment simulation, is considered during the gear contact stress analysis. Stresses from forming operations can also be used as a starting condition for the DANTE heat treatment simulation.
The animation shows the use of DANTE heat treatment simulation software in modeling a low pressure carburization process of a high alloy steel with strong carbide forming elements (e.g.; Cr, Mo, V). The animation shows the prediction for carbon in the austenite matrix (left), carbon in carbide form (middle), and a relative carbide size (right). There is a total of 34 boost/diffuse steps, plus a final diffuse to help dissolve the carbides and achieve the correct case depth.
Animation shows the top view of a DANTE heat treatment simulation of a thin ring undergoing a 2-bar high pressure gas quench. There is a directional gas flow from bottom to top; simulating a front to back gas flow in the high pressure chamber. The distortion has been magnified 50X to clearly show the movement created by the nonuniform cooling and the resulting out of round distortion.
