Processing of ultralow carbon pipline steels with acicular ferrite
, 2004 Acicular ferrite microstructure was achieved for an-ultralow carbon pipeline,steel through the improved thermomechanical control process (TMCP), which was based on the transformation process of deformed austenite of steel.

A new inexpensive method for the preparation of acicular precursors for magnetic recording media
, 1997 Magnetic materials meant for audio/video recording applications necessitate that polycrystalline materials be in acicular shape. So preparation of acicular precursors for magnetic storage materials assumes significance.

Magnetic properties of acicular ultrafine iron particles
, 2002 The magnetic properties of acicular ultrafine iron particles are studied. The introduction of high recording densities on recording media has meant a dramatic bit size reduction and track density increase on the media surface.
