Übersetzung für "Stress relief annealing" in Deutsch

Another variant of induction annealing is stress-relief annealing.

Stress-relief annealing also falls under this category.

The finished cellular wheel is preferably subjected to stress-relief annealing.

This preferably takes place in the form of stress relief annealing in an annealing furnace.

By stress relief annealing of the strips, largely stress-free sheets can be produced.

Stress relief annealing is characterized in that the solidification is largely maintained.

During the stress relief annealing, other material properties such as strength and ductility are not significantly changed.

Internal stresses below the straightening limit may be reduced but not completely eliminated by stress-relief annealing.

Stress-relief annealing is also used for the heat treatment of workpieces with high internal stresses.

Moreover, stress-relief annealing often causes relaxation cracks in the overheated area of the thermal influence zone.

In order to achieve adequate resistance to failure by embrittlement, even without the otherwise necessary stress-relief annealing, it is known from German OS No. 1 527 259 to apply a buffer-layer to the abutting surface of the said end-part, to subject the said end-part, which is still usually transportable, and the said buffer-layer, to stress-relief annealing, and then to unite the said end-part and the multi-layer container-part by means of an assembly weld-seam.

In all cases, after the thermal spray-on, the catalyst can be subjected to a stress-relief annealing process by tempering at relatively high temperatures.

If the carrier body is warmed up during the application of the alloy elements and thereby the cooling-down process is slowed, the stress-relief annealing can be omitted.

This risk can be minimised if the processed component is subjected to stress relief annealing after the roughing operation at 140 ° C for 2 hours and only then is finished.

Instead, the piston blank resulting from friction-welding is only subjected to tempering or stress-relief annealing, in order to reduce any stresses that might be present.

Because the hardness of the quenched and tempered material of the piston blank also decreases slightly outside of the heat influence zone, as the result of tempering or stress-relief annealing, the heat influence zone is essentially maintained.

It has proved particularly advantageous here if the hardened molding material mixture is removed from the cells of the cellular wheel only after the stress-relief annealing.

The finished cellular wheel is expediently subjected to stress-relief annealing, the hardened molding material mixture preferably being removed from the cells of the cellular wheel only after the stress-relief annealing.

The drive shaft 30 with the then finished cellular wheel 10, the cells 22, 24, 26 of which are still filled with the hardened molding material mixture F, is then subjected to stress-relief annealing at a temperature of, for example, 550° C. for three hours.

During the stress-relief annealing, the inhomogeneous stress field which is produced during the joining of the end edges of the fins to the following sleeve merges into a state of equilibrium with a homogeneous stress field, with the result that, after the subsequent removal of the basic molding material from the cells, the cellular wheel is free of distortion and accordingly balancing can be dispensed with.

If specifically required, the component can be subjected to a furnace treatment, for example a stress-relief annealing, but normally this is not necessary, as due to the very high temperatures during operation low stresses in the components repaired according to the invention are quickly relieved anyway.
