Abstract
The thermodynamic expressions used to express the nitrogen concentration in iron based alloys prepared under high pressure requires the explicit use of pressure terms. The nitrogen concentration follows Sievert's law for low alloy additions, but significant deviations are observed at higher alloy additions. This Bureau of Mines study extends these new thermodynamic results to higher pressures (200 MPa) and to a greater range of iron alloys: Fe-(0-30)Cr-(0-30)Mn-(0-30)Ni. The experimental results also show that pressure-alloy concentration effects exist.
