The research activities have been concentrated on many different fields, including the development of high pressure die casting process and semi-solid processing, development of high strength wrought alloys and components, and characterization of microstructure, mechanical properties as well as corrosion properties.
Since the mechanical properties of the final cast products are significantly affected by the castability of the reheated billets, the SSP of Mg alloy components requires reliable production of the high quality Mg billets for the subsequent SSP.
One of the most important factors in casting Mg alloy billets is the safety of the process.
New wrought Mg alloys with better mechanical properties have been developed at SNU [16].

It focuses on the effect of important process parameters on the microstructure and mechanical properties of the resulting part.
Parts with better optical, thermal, electrochemical, and mechanical properties have been obtained.
Starting from the raw material, the powder grain size affects the density and consequently the mechanical properties of the produced parts [95, 96].
Some studies showed that AM produced Inconel 718 (UNS N07718) parts contained small cracks that may affect mechanical properties in all directions especially in the building direction [100-102].
These factors affect the density of additive parts and consequently all the mechanical properties and material characteristics.

Because of bioinert of nature of alumina, it has lack of bioactivity properties even though provides a very high mechanical properties [1].
The factors that affect the osteoconduction in the porous materials are the pore size, pore shape, pore connectivity, and bioactivity.
The effect of slurry compositions on the physical properties Sample no.
The pore size of pure alumina body (sample 1) were largest thus give low in density and low mechanical properties.
As the HA-to-alumina mass ratio increased from 0.2 (sample 2) to 0.8 w/w (sample 5), the pores become interconnected with more dense and thicker pore wall and it is important factors that improve the mechanical properties of the porous sample [8].

And its mechanical properties are not consistent.
Moreover, there are weld defects, stress concentration, the microstructure and mechanical properties change as well as residual stress in welded joint [4-6].
The chemical composition and the mechanical properties of the alloy is listed in Table 1.

The effect of aluminium sulfate on cement properties was studied systematically and the mechanism was analyzed using XRD and SEM tests.
Multiple measurements are employed in this paper to study systematically the formation and development regulation of cement under the action of aluminium sulfate, such as setting time, fluidity, drying shrinkage and mechanical properties.
As can be seen from the above study, different content of aluminium sulfate has different effect on the properties of cement.
That is, the concentration of calcium in liquid and the PH are main factors.
