Aerospace Heat Treating

Heat Treatments for the Aerospace Industry

We maintain the equipment to perform several different treatments that are commonly required to allow Aerospace components to meet industry standards. TMT is a full-service commercial heat treater with the ability to treat production runs, one-offs, R&D projects, breakdowns, and expedites in all volumes.

​Age Hardening

Age Hardening, or Precipitation Hardening, holds the component or components at a specified temperature to form small, alloy-rich precipitates that form a hard, protective shell.

Annealing

This group of treatments softens a material to improve its machinability or electrical conductivity, allow for cold work, reduce residual stresses, or increase the material’s dimensional stability.

Carbonitriding

In this treatment process, we diffuse nitrogen and carbon into a part at an elevated temperature, then quench the part in order to form a hard outer surface layer.

Carburizing

Similar to carbonitriding, carbon is diffused into a part at elevated temperatures and then quenched, forming a hard, durable outer layer.

Induction

Induction is a treatment process in which a part is placed inside a copper coil and heated by a high-frequency, alternating current, then quenched.

Normalizing

In Normalizing, we heat and then hold the part above its critical temperature, and then air-cool it to form a more homogenous structure.

​Solution Annealing

Solution Annealing is the process in which parts are heated to a temperature at which secondary phases dissolve into a single phase and then cooled to prevent secondary phases from precipitating.

Through Hardening

Through Hardening is a group of processes in which we heat parts in a furnace, and then cool them quickly to increase their hardness and strength. We often temper parts after this process as well to achieve a desired strength and toughness balance.
