Effect of Zn and Mn Additions on the Wear Resistance of Cast Alloy Mg – 5% Al – 1% Si

  • Published:
Metal Science and Heat Treatment Aims and scope

The effect of additions of Zn and Mn (from 0.5 to 4%) on the microstructure of alloy Mg – 5% Al – 1% Si is studied by the methods of x-ray diffractometry and light and scanning electron microscopy. The strength parameters are determined in tensile and wear tests. It is shown that particles of Mg2Si precipitate in the matrix and particles of Mg17Al12 precipitate on grain boundaries upon the introduction of low contents of Zn and Mn. Phases MgZn and Al6Mn precipitate at a high content of the additions. An optimum concentration of Zn and Mn is chosen for raising the wear resistance of alloy Mg – 5% Al – 1% Si.
