Attrition milled, nanostructured iron-based powders were compacted at temperatures less than one half the melting temperature and at pressure in excess of 1GPa and resulted in full dense samples from which macroscopic properties could be determined.

A series of Fe–18Cr–18Mn–N–C alloys was produced and evaluated to determine their mechanical and hardness properties. In one group, different levels of nitrogen and carbon were added to a base composition of Fe–18Cr–18Mn. The base Fe–18

A new processing technique makes nitrogen alloying possible by adding nitrogen under elevated nitrogen pressure to prealloyed Fe-C ingots during continuous casting, producing a whole new class of precipitation-free, iron–carbon–nitrogen alloys. W

The consolidation behavior of two types of nanoscale iron powders-vacuum condensed (nanograins in nanoparticles) and ball-milled (nanograins in microparticles), was studied. The consolidation of two microscale powders, atomized and ground, was also c
