This white paper investigates the effect of solution heat treatment as well as primary and secondary aging treatment conditions on the microstructural evolution of a high-entropy superalloy.

SECO/WARWICK will deliver a solution heat treatment line to Tata Advanced Systems Limited (TASL), an Indian manufacturer in the aerospace sector. The order is the largest production line for aircraft skins in the history of both companies. SECO/WARWICK will build a production line for the solution heat treatment of aluminum alloys. It will meet the stringent requirements for AMS 2750F and AMS 2770 standards. The equipment will be used for the production of aircraft skins, empennage and center-wing boxes. The line includes a rapid-quench electric furnace (drop-bottom type), mobile quenching tank, rinsing tank and additional equipment (including a chiller and loading baskets).

 

A Virginia-based manufacturer of high-quality plumbing tube commissioned a SECO/WARWICK solution heat-treat furnace to expand its capabilities to include aluminum extrusions. This is the first installation of new aluminum-processing equipment at the plant. Tubing extrusions and other shapes up to 26 feet long are loaded horizontally at floor level into a load carriage. The carriage containing the load is then pulled by a hoist from one end until it is vertical next to the furnace. The carriage is then secured to the supporting structure, allowing the hoist to lower the load down and out of the carriage. The load is lowered into a powered rotating carousel, which contains two submerged drywells that extend below the floor into the water-filled pit. The load is then supported by the carousel, allowing the hoist to be released. The carousel rotates until the load is in position directly below the furnace. The furnace door opens, and a second hoist retrieves the load, pulling it up into the furnace chamber for heating.

During World War II, there was a need to heat treat large tank parts for use in the North African theater. Cincinnati, Ohio-based Derrick Company, a local brick-maker, devised a way to use their brick-making kilns as heat-treating ovens.

Wisconsin Oven Corp. shipped two industrial ovens to United Tool & Die Co. of West Hartford, Conn.
