Preparation method.
Background technique
The shortage of resources and environmental degradation of 21 century becomes the matter of utmost importance for influencing human social.Relative to
Increasingly for exhausted various metals mineral resources, magnesium has more potentiality with its reserves abundant.Magnesium density is about 1.74g/cm3,
It is the 2/3 of aluminium alloy, the 1/4 of steel, it is available most light commercial metal structural material.It is with specific strength specific stiffness simultaneously
Height, damping property, electromagnetic shielding and capability of resistance to radiation are strong, Cutting free processing, the advantages that can be recycled, in automobile, electronics, electric appliance, friendship
The fields such as logical, aerospace have broad application prospects, and are the lightweight metals to grow up after steel and aluminium alloy
Structural material is provided simultaneously with degradable biological medical material and air/secondary cell functional material prospect, is known as this century
Green engineering material.But the reasons such as its absolute intensity is lower, corrosion resistance is poor, room temperature forming capacity difference greatly limit magnesium and
The further wide application of its alloy.
Especially because the crystal structure of magnesium and its alloy is close-packed hexagonal, it is mainly base under the conditions of low temperature (220 DEG C of <)
Face sliding, slip system cause its plasticity bad less, and easily formation fibrous texture or plate are knitted during extruding or rolling deformation etc.
