Powder Metallurgy

Powder production

• mechanical alloying (MA) of elemental powder mixtures

• ball milling (BM) of pre-alloyed master alloys

• mechanical milling (MM) of single-phase materials

• pulverization of melt-spun ribbons

Powder consolidation

• cold and hot pressing
• hot direct extrusion
• in-situ consolidation during mechanical alloying

Samples prepared by PM are characterized by:

•  X-ray diffraction (XRD)

• scanning electron microscopy (SEM)
• transmission electron microscopy (TEM)
• differential scanning calorimetry (DSC)
• thermal mechanical analysis (TMA)
• chemical analysis
• compressive and tensile testing
• microhardness and nanoindentation
• density measurement
