Powders of ZrB2, HfB2, SiC, TaSi2 and Y2O3 (Table 1) were weighed to reach the target compositions (Table 2).
Table 1: Grade, purity, particle size and measured density (helium pycnometry) of starting powders.
Both were measured on ¼ μm polished surfaces by Vickers’ indentation with a load of 98 N for HPed samples and a load of 1 kN for SPSed samples.

Figure 1.
Typical deformation microstructures that develop in an austenitic stainless steel during warm working are shown in Fig. 1.
The strong temperature/strain rate dependence of dq/de in the range of hot working under conditions of Z < 1012 s-1 becomes much weaker in the range of warm working at Z > 1012 s-1.

Using the thermal analysis tool it is possible to identify the specific solidification differences between cast irons with representative graphite morphologies [1-10].
Background Figure 1 shows aspects of a typical cooling curve and its first derivative for a hypoeutectic grey iron and the significance of the most important events and parameters on these curves, referring to the equilibrium temperatures in the stable and metastable systems.
To compare inoculation efficiency, a new method [ISF – Inoculation Specific Factor] was developed that compares un-inoculated iron and inoculated iron [Eq. 1].

Introduction
In recent years, electromagnetic wave absorbing materials have attracted considerable attentions because of their wide applications in civil and military [1-2].
Results and discussion Fig.1, Density of Si3N4-SiC composite ceramics with different SiC content at 1750°C Microstructure and phase composition.
With increasing SiC content, the relative density of the sintered samples decreases, as shown in Fig.1.

Introduction
Medicinal Botanical garden has not only the generality but also its own characteristic because of the medicinal plant.About the function and mission of the medicinal botanical garden in 21 century, director of the royal botanical garden-kew garden Crane has summarized in three aspects,scientific research,popular science and protection. [1]The author thinks , as the the pool of medicinal plant resources, there are lots of difference among all the medicinal botainal gardens based on the local environment, the building purpose and the development, even though, all of them showed or implied their diversified functions,except the functions Crane mentioned above, assisting practiec teaching in colleges and universities,planting technique demonstration,specialized resources demonstration and many potential functions which need us to explore.
Set up the whole process and use tracking management to strengthen ex-situ preservation function of the medicinal botanical garden for the endangered medicinal plants. 1) Face up to the reality challenges of the ex-situ preservation for the endangered medicinal plant resources.
