AlMn Alloy

A strong, lightweight, versatile alloy that can be fabricated into a wide variety of shapes and sizes. It is most commonly used in applications requiring good corrosion resistance, workability and weldability. This alloy is available in many tempers. It can be hot worked to high tensile strengths and has good cold working properties, especially in the T451 temper. It is a good choice for applications that require high strength, damage tolerance and good weldability in a wide temperature range.

AlMnZr alloys contain small amounts of Zr (marked as az in the table below) in order to enhance their high temperature mechanical properties by pinning dislocations and retarding recovery and recrystallization processes. The addition of az also reduces the formation of coarse primary particles in these alloys during solidification and subsequent thermal treatment.

The deformation mechanisms in these materials depend on the microstructure changes that occur during exposition to elevated temperatures as documented by the course of hardness curves (Figure 3). The slight softening observed in all ECAP materials can be explained by the decrease of grain size that occurs after four ECAP passes. This relates to the loss of a small portion of the original fine-grained microstructure and is associated with a moderate value of ductility and with a low parameter m.

The microstructure of the annealed material consists of a mixture of large coarsened grains and surviving fine grains as shown in Figure 5 (a, b). The existence of very large grains in this region documents that the tensile testing temperature of 400 degC is above the recrystallization temperature for these alloys.
