4.1 Aluminum alloys are usually heat treated in molten salt baths or air chamber furnaces; however, lead baths, oil baths, fluidized beds, or even superheated steam may be used in specific applications. However the use of uncontrolled heating is not permitted.

1.1.1 The heat treatment of aluminum alloy castings used in speciÞc aerospace applications is covered in AMS 2771 2 and speciÞc AMS 2 material speciÞcations.

This practice is intended for use in the heat treatment of wrought aluminum alloys for general purpose applications. Aluminum alloys are typically heated in air chamber furnaces or molten salt baths. Though lead baths, oil baths, or fluidized beds may …

A new ASTM International standard will help those who both provide and use induction-heat treatment to strengthen metals. While guides and specifications already exist to qualify standard heat treating furnaces, this new standard will be the first generally accepted guide for qualification of induction heat treating, which heats metal ...

Precipitation heat treatment shall conform to the prescribed times, temperatures, and annealing procedures. The alloys shall be subjected to tensile testing, eutectic melting and heat-treat-induced porosity analysis, intergranular corrosion test, and Alclad diffusion test.

2017年2月21日 · In general, heat treatment is the term for any process employed which changes the physical properties of a metal by either heating or cooling. When properly performed, heat treating can greatly influence mechanical properties such as strength, hardness, ductility, toughness, and wear resistance.

1.1.1 The heat treatment of wrought aluminum alloys used in specific aerospace applications is covered in AMS 2772.2 1.1.2 Heat treatment of aluminum alloy castings for general purpose applications is covered in Practice B 917/B 917M. 1.2 Times and …
