Glide Stress by Stationary Creep of Tempered Martensite with Polyhedral Particles

Creep stress transfers matrix‐particle in conjunction and disjunction particle matrix are examined. The effect of angles creep stress, dislocation glide, and stress transfer particle face on dislocation glide, and climb components of creep stress are calculated. The glide force and gliding velocity in particles disjunction matrix are deduced. The interaction acting stress (σa) – polyhedral particles is examined by a model based on linear mechanics. The glide component (σg) of acting stress decreases to σg = 0.023 σa, governing gliding velocity and creep rate. The gliding velocity gv = 558 nm s−1 and ferrite lattice glide resistance Rg = 3.16 × 10−13 N are calculated.
