Orowan strengthening is a key strengthening method for metallic materials. However, a
debate still exists on the effect of temperature on the Orowan strengthening mechanism …

In this paper, the first investigation of the Orowan strengthening mechanism in the thermal
plastic regime of body-centered cubic (bcc) materials is made with dislocation dynamics …

The conventional role played by precipitates in crystalline solids is in blocking the motion of
dislocations and for consequentially hardening, a mechanism attributed to Orowan's finding …

The interaction between glissile dislocations and precipitates within a continuum is
responsible for marked increases in material strength. Due to their desirable engineering …

Many common engineering alloys are strengthened by precipitates with plate-like
geometries. The mechanics of precipitation strengthening, while well resolved with spherical …

Precipitation strengthening is a key strengthening method for metallic materials. However,
the temperature effect on precipitation strengthening is still unclear to date. Based on …

Strengthening by needle-shaped β′′ precipitates is critical in Al–Mg–Si alloys. Here, the
