However, compared to the mechanical properties of natural bone, HA ceramics need improvement [2, 3].
Thus, since nickel-free austenitic stainless steels seem to have better mechanical properties, corrosion resistance and biocompatibility compared to 316L stainless steels [9], it is possible that composite made of this steel and HA could have improved properties.
The purpose of this paper is to report on the processing as well as mechanical properties and corrosion resistance of the nickel-free austenitic stainless steel/HA nanocomposites.
Nitrogen in solid solution is the most beneficial alloying element in promoting high strength in austenitic steels without affecting their ductility [11].
That improved properties combined with excellent biocompatibility of HA could help to obtain better biomedical implants with better mechanical properties, corrosion resistance and biocompatibility.

To achieve the ideal conditions of hygrothermal comfort inside a building, it is necessary to have greater control of the factors that influence those conditions, both interior temperature and relative humidity, which are affected by climatic conditions and the use of the buildings, as well as the characteristics relating to the geometry, location and facade composition.
The main focus was the determination of mechanical properties and an assessment of the performance of walls built with hydro gypsum block included tests of water tightness, adhesion and impact.
Mechanical properties The mechanical properties results showed that the hydro samples with 0.3% of water repellent additive content present higher flexural strength values when compared with the samples with 0.1% water repellent additive, 1.9 MPa and 1.7 MPa, respectively.
