The important new material of the industry such as space flight and military project weapon, today that especially mankind pay special attention to the energy and environment, magnesium close
Golden product receives increasing attention, and has wide market development application prospect.
The Plastic Forming of magnesium alloy has turned into the important directions of current research and development of magnesium alloy, and magnesium alloy structural part is still main at present
Manufactured by die-casting technique, but defects of die casting such as hole, be mingled with etc. and to greatly reduce magnesium alloy mechanical property.By contrast, magnesium closes
The part tissue of golden Plastic Forming more refines, composition evenly, it is internal more closely knit, therefore wrought magnesium alloy has high intensity and height
The advantages that elongation percentage, higher design requirement is disclosure satisfy that, but the plastic deformation ability difference of magnesium alloy causes its plasticity to add
Work and its difficulty.
Magnesium is Patterns for Close-Packed Hexagonal Crystal structure, and particularly its shafting compares c/a=than c/a=1.624 close to preferable axle
1.63,.More grained magnesium alloys can only be typically plastically deformed by basal slip and twin sliding, and independent slip-system is few, thus
Be difficult to as low axle than six side's Titaniums, zirconium etc. good plasticity can be shown by faceted pebble, the common sliding of the conical surface.Magnesium at room temperature
Alloy only has two independent slip-systems, far from meeting von Mises criterions, therefore intercrystalline compatibility of deformation under external force
Scarce capacity.
Deformation temperature is to influence the key factor of magnesium alloy plastic deformation ability, and when temperature is high, nonbasal slip system starts
Required critical resolved shear stress substantially reduces, thus can activate faceted pebble and conical surface sliding, and this makes magnesium alloy that obvious ductility be presented
Transformation, plasticity significantly improve.Therefore, the key factor of the plastic deformation ability of magnesium alloy, the plasticity of magnesium alloy are influenceed during temperature
Forming temperature section is narrower, typically in 300~450 DEG C of section, when forming temperature is low, and magnesium alloy deformation ability, easily
Cold crack is produced, when temperature is too high, some low melting points in alloy may mutually melt in forming process, under stress easily
Fire check is produced, in addition, forming temperature is too high, the coarse grains of part microscopic structure is will also result in, directly affects material military service
Performance.
During magnesium alloy rolling, temperature must be lubricated to roll and magnesium plate band in time when raising, lubricating system
The deformation heat and frictional heat of metal can be taken away, adjusts roller surface temperature, controls template, ensures rolling efficiency and safety, simultaneously
The friction between roll and strip can be reduced, there is provided stable frictional interface, prevent glutinous roller, realize stable rolling, improve surface
Quality.
The magnesium alloy plate and belt market demand, the development trend of application are wide cut and cost degradation.Wide cut is magnesium alloy
Strip meets the primary condition of the communications and transportation industry lightweight needs such as Aero-Space and automobile, and cost degradation is magnesium alloy plate
The essential condition that band can compete with other materials.Due to having production continuous with rolling method production magnesium alloy thin dimension board band
Change degree is strong, product size tolerance variations are small, control easy to automate, high yield rate, production cost is low and can advise greatly
Mould carries out the significant advantage such as industrialized production and marketing application, thus, the rolling method production of magnesium alloy board turns into current
