Mathematical modeling of nanodispersed hardening of FCC materialsOleg Matvienko1,21. National Research Tomsk State University摘 要:The plastic deformation... loops are higher in alloys strengthened with coarse particles than in alloys strengthened with fine particles. At small distances between the strengthening particles, this effect is the most pronounced......
corrosion cracking. Therefore, creep age forming (CAF), a favored forming process which combines creep deformation and age-hardening, is explored [5-8]. Constitutive modelling and springback prediction...-based unified creep constitutive equations with three state variables in sinh function to model primary creep hardening and tertiary creep softening in aluminum alloys by mechanisms of 1) dislocation......
