Fig. 4—Evaluated Ni tracer self-diffusion coefficients (DNi*) and average interdiffusion coefficients (Dave) for Ni silicides at 900 ⬚C along with the nearest Ni-Si interatomic distances.[22,23] (1 ⫽ low-temperature form of Ni3Si, ␥ ⫽ Ni5Si2, ␦ ⫽ low-temperature form of Ni2Si, and ⫽ hightemperature form of Ni2Si).
Fig. 5—Calculated and measured[17] thicknesses of the reaction layer ␥ (Ni5Si2) in the Ni3Si/Ni2Si diffusion couple vs 冪time. The light solid and dotted lines are according to DICTRA software, whereas the fat solid lines are from the present approach.

A New Model to Explain the Unusual Tensile Behavior of High Martensite Dual-Phase Steels ASIM BAG and K.K. RAY Recently, the authors have developed a series of high martensite dual-phase (HMDP) steels containing 0.3 to 0.8
the integral in Eq. [5] is dominated by the value of at the stoichiometric composition and depends only marginally on the actual width of the homogeneity range of the phase (as long as
