Analysis shows that additives are introduced late and require sufficient processing time;
Particular attention must be paid to adding components other than aluminum when processing steel in a furnace because the trace compounds they create have a serious negative effect on the quality of the steel.
Inert gas purging and synthetic slag treatment lead to more efficient removal of non-metallic compounds [14].
A lime-clay mixture was used to reduce the amount of sulfur in the liquid metal, a lime-iron mixture was used for dephosphorization, and an acid mixture was used to reduce the amount of oxygen and oxide compounds.

The influence of withdrawal rate on microstructure and mechanical properties of directionally solidified alloys and single crystal alloys has been studied, mainly focusing on the morphology of solid-liquid interface, (γ+γ¢) eutectic, γ¢ precipitates, as-cast voids and so on[1,2].
The aim of withdrawal rate research is to master the law of directional solidification, control the microstructure of alloy and achieve the best mechanical properties.
The microstructure of the as-cast and heat-treated alloys with different withdrawal rates was observed.

Previous studies reported on a favorable biocompatibility of the alloys LAE442
and MgCa0.8.
The measurement of the cross sectional area confirmed the macroscopically described corrosion of both alloys.
Both alloys showed an additional loss of volume of ~ 20 % in comparison with the six months group.
Summarized, the present study could show a further progressed degradation of both alloys after the elongated implantation period of 12 months.

Therefore, the aim of the present study is to discover the optimal conditions for the synthesis of
calcium phosphates with different composition and crystal phase.
Results and discussion The Ca/P molar ratio of the three kinds of calcium phosphate compounds (hydroxyapaite, calcium phosphate and calcium pyrophosphate) were selected as initial Ca/P molar ratio.

However, with the rapid development of new energy vehicles and other industries, people have put forward higher requirements for the performance of aluminum alloys and their composites.
In order to improve the performance of aluminum alloys and composites, graphene-reinforced aluminum-matrix composites have gradually become research focus of metals matrix composites [2].
It can be considered that the nano-copper-modified graphene and the matrix were mainly combined by the alloying of the nano-copper layer and the aluminum matrix to form intermetallic compounds [16,17].
