Preparation of Mg-Al-Zn Type Sintered Alloy by Mechanical Alloying Method and its Mechanical Properties

Mg-Al-Zn type mixed powder was mechanically alloyed (MA) by using a planetary ball mill under Ar atmosphere. The MA powders were sintered by vacuum hot pressing (HP). The change of constituent phase of HP materials was examined by XRD and FE-EPMA. Its mechanical properties were evaluated by Vickers hardness and compression tests. HP material was obtained by processing MA powder with mean particle size of 5.6μm at 673 K for 18 ks. Its hardness...
