P.032.5 Portland cement (28-day compressive strength of 32.5 MPa) was used as a cementitious material.
(3) With the number of SCFT increases or solution concentration increases, the peak stress of both RCS and common CS reduces gradually, peak strain decreases gradually, and material brittleness increases.

Therefore, NC materials have a great potential in technological applications.
Especially the segregation of solute atoms at GBs can significantly reduce the GB energy and enhance the stability of NC material which has been confirmed in a couple of NC materials [3-13].
On this basis, a novel method of understanding and synthesizing NC material was proposed by introducing defactants (segregating solute atoms) into the materials to favour the formation of GBs and enhance the formation ability of NC material.
Fabrications of NC iron or iron-based alloys are always an important topic in the field of materials science.
As is well known, formation of NC materials in SPD processes is related directly to the formation/evolution of GBs.

Therefore, the biocompatibility of Si-HA seems to be good and it is a feasible material as bone substitute.
Materials and Methods Preparation of 2wt% Si-substituted Hydroxyapatite The 2wt% Si-substituted hydroxyapatite (Si-HA) was prepared using a precipitation method.
Based on these results, the 2wt% Si-substituted hydroxyapatite has good biocompatibility and seems to be an useful material for implants and bone substitutes.
