However, the loess belongs to the category of silt and silty clay, the shearing strength largely comes from the cohesion of soil, which is supplied by its fine grain and cementitious materials.
Nevertheless, these substances with strong water sensitivity that most cementing material is dissolved under the action of water, the cementation of the fine grained transform into lubrication, the shearing strength of the loess is loss partly under the state of soaking and which being to metastable state.

In this case, the microhardness values of films mainly strengthen by nanocrystallite-size hardening, which described the effect of an increased strengthening with decreasing grain size in materials and solid solution hardening according to the rule of mixtures in the FCC CrN type MeN.
From literature [14], when the grain size was less than approximately 10 nm, further reduction in grain size would lead to decrease in microhardness, especially the microhardness of amorphous material was lower than the nanocrystalline material.
