The 1xxx, 3xxx, and 5xxx series wrought aluminum alloys are non-heat treatable and are strain hardenable only. The 2xxx, 6xxx, and 7xxx series wrought aluminum alloys are heat treatable and the 4xxx series consist of both heat treatable and non-heat treatable alloys. The 2xx.x, 3xx.x, 4xx.x and 7xx.x series cast alloys are heat treatable. Solution and age: Aluminium alloys. There are a number of wrought and cast aluminium alloys that can be strengthened by solution treating and aging to a variety of different tempers. Benefits. The mechanical properties of heat treatable alloy components can be optimised by the selection of an appropriate solution and age process sequence.
Commercial alloys whose strength and hardness can be significantly increased by heat treatment include 2xxx, 6xxx, and 7xxx series wrought alloys and 2xx.0, 3xx.0 and 7xx.0 series casting alloys. Some of these contain only copper, or copper and silicon as the primary strengthening alloy addition. Aluminium alloys can be improperly heat treated. This causes internal element separation, and the metal then corrodes from the inside out. Aluminium alloy compositions are registered with The Aluminum Association.

Heat Treating Aluminum AlloysManufacturer: Reynolds. Volume 4E examines the heat treating process as it applies to nonferrous metals and alloys. It covers aluminum, copper, nickel, and titanium in detail, describing accepted heat treating practices and how they drive metallurgical transformations that ultimately determine material properties.
The volume also contains information on quenching, distortion, and. This article presents a detailed discussion on typical thermal treatment practices for hardening of various aluminum casting alloys.
These practices are solution treatment, quenching or cooling, preaging, and artificial aging at an elevated temperature. Book • Edited by: castings can be heat treated by a newly developed procedure now means that consideration can be given to designing HPDC alloys specifically for heat treatment, while retaining high castability.

The benefits and advantages of polymer quenchants are also examined. Scott MacKenzie, PhD. aluminum heat-treating will be shown, with possible corrective actions. Introduction Aluminum in many forms has been used in aircraft since the early beginning. This is because aluminum alloys can be heat-treated to relatively high strengths, while maintaining low weight.
It is easy to bend and machine, and cost of material is low. Because of these. The general types of heat treatments applied to aluminum and its alloys are: Preheating or homogenizing, to reduce chemical segregation of cast structures and to improve their workability Annealing, to soften strain-hardened (work-hardened) and heat treated alloy structures, to relieve stresses, and to stabilize properties and dimensions.
The typical aluminum heat treatments are annealing, homogenizing, solution heat treatment, natural aging, and artificial aging (also known as precipitation hardening).
Depending on the exact process being used, furnace temperatures can range from to °F. The heat treatment of heat treatable aluminum alloys is a very sensitive and specialized subject.
The strengthening of the heat treatable alloys necessitates what would appear to be a very simple procedure known as solutionizing.

In-depth articles provide details on the heat treating principles and practices of aluminum, copper, nickel, and titanium alloys. Quenching, distortion, residual stresses, and alloying effects are given special focus, and attention is given to the complexities of aging practices and microstructural development for the major and less common.
Here's a rough specification: The book needs to address in handbook format the common low alloy, corrosion resistant, and basic tool steels, copper and aluminum alloys in general theory and particular application. Also charts and graphs of heat treating practices and property enhancements resulting from heat treating.

Solutionizing Stage • Take metal temperature up to just short of the liquidus • Do not melt the casting • Dissolve all of the solute into the aluminum • Quench the metal • Create a Super-Saturated Solid.
Wrought alloys that constitute heat-treatable (precipitation-hardenable) aluminum alloys include the 2xxx, 6xxx, 7xxx, and some of the 8xxx alloys.
The various combinations of alloying additions and strengthening mechanisms used for wrought aluminum alloys are shown in Table 1. The strength ranges achievable with various classes of wrought and.
Annotation Examines characteristics of wrought and cast aluminum alloys, then presents basic aluminum alloy and temper designation systems, as developed by the Aluminum Association, and explains them with examples.
Wrought and cast aluminum designations are treated in a similar fashion. Processes used to produce aluminum alloy products are described briefly, Reviews: 1. AlSi10Mg alloy made by conventional casting is normally subjected to a T6 heat treatment in which solution treatment is carried out at around °C followed by ageing at temperatures in the range –°C, with a view to achieving precipitation hardening by via Mg2 Si.
Aluminium alloys have undergone a dramatic transformation in areas of extrusion, machining, welding, heat treatment, structural changes, created by ultra fine particles and enhanced corrosion resistance.
Hence, these alloys have made rapid gains in European automotive and space industry. These developments have been described by experts in the book. Two of the major families of heat treatable aluminum alloys containing magnesium and silicon are the 6xxx series in wrought aluminum alloys, and 3xx series in casting aluminum alloys.
Al-Si-Cu/Mg alloys are well studied and there exists a lot of publication about the effect of alloying elements and solidification rate on the microstructure.In this entry, the industrial heat treatment processes applicable to age-hardenable aluminum alloys are described.
Particular emphasis is given to the main stages of heat treatment and how each of these influences microstructure and properties of engineering alloys.The general types of heat treatments applied to aluminum and its alloys are: Preheating or homogenizing, annealing, solution heat treatments, precipitation heat treatments.
This work relates to the understanding of the temper designation system for both wrought and cast aluminium alloys. System of aluminium alloys and temper is stated at.
