Extruded powder metal compact

A powder metal compact, comprising

• a substantially elongated cellular nanomatrix comprising a nanomatrix material;
• a plurality of substantially elongated dispersed particles comprising a particle core material that comprises Mg, Al, Zn or Mn, or a combination thereof, dispersed in the cellular nanomatrix;
• and
• a bond layer extending throughout the cellular nanomatrix between the dispersed particles, wherein the cellular nanomatrix and the dispersed particles are substantially elongated in one predetermined direction, and wherein the nanomatrix and the dispersed particles are elongated in the predetermined direction to an extent that the nanomatrix and dispersed particles become separated, cracked or otherwise substantially discontinuous in the predetermined direction.
