M&G Recovery Fund is a British open-ended investment company launched on 23 May 1969 and, as of 31 May 2012, was the third-largest [1] open-ended fund in the UK (behind Neil Woodford's two equity income funds) with £7.4 billion of assets.
The yield strength increases linearly with increasing Mg content from about 45 N/mm 2 at 1% Mg to about 120 N/mm 2 at 4% Mg. The tensile strength also increases linearly, but with a steeper gradient. With 1% Mg it is about 60 N/mm 2, with 4% Mg 240 N/mm 2. [20]

Alloy 5083 retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys with an Ultimate Tensile Strength of 317 MPa or 46000 psi and a Tensile Yield Strength of 228 MPa or 33000 psi. It is not recommended for use in temperatures in excess of 65 °C. [2]
The quadratic Hill yield criterion for thin rolled plates (plane stress conditions) can be expressed as + (+) (+) + = where the principal stresses , are assumed to be aligned with the axes of anisotropy with in the rolling direction and perpendicular to the rolling direction, =, is the R-value in the rolling direction, and is the R-value perpendicular to the rolling direction.
If cold forming (in the quenched or cold-hardened state) is followed by hot forming, this takes place more quickly, but the strength that can be achieved is reduced. The higher the strain hardening, the higher the yield point, but the tensile strength does not increase. If, on the other hand, the cold forming takes place in the stabilized state ...
The strength of magnesium alloys is reduced at elevated temperatures; temperatures as low as 93 °C (200 °F) produce considerable reduction in the yield strength. Improving the high-temperature properties of magnesium alloys is an active research area with promising results.
Metal forming operations result in situations exposing the metal workpiece to stresses of reversed sign. The Bauschinger effect contributes to work softening of the workpiece, for example in straightening of drawn bars or rolled sheets, where rollers subject the workpiece to alternate bending stresses, thereby reducing the yield strength and enabling greater cold drawability of the workpiece.
