Grain size and latency

WebThe driving force for grain boundary migration is mainly the interfacial energy of the grains. 10 Because of the large initial grain size, the final grain size of the 80 or 99 nm powder compact is larger than that of the 55 nm powder compact, as shown in Fig. 5(d–f). From the abovementioned findings, the preference for the densification of ...

Step-by-Step Guide for Grain Size Analysis

WebThe grain boundary refers to the outside area of a grain that separates it from the other grains. The grain boundaries separate variously-oriented crystal regions (polycrystalline) … Websizes, the values of typical mechanical properties increase with the reciprocal root of the grain size. The classic Hall-Petch equation relates the yield strength to the grain size: σ y = σ 0 + Kyd-1/2 (1) where Ky is the Hall-Petch slope and d is the mean grain size. An identical relation holds for the
