The alloy has excellent corrosion resistance and good mechanical properties, processing properties, which has been widely used as a material of corrosion-resistant equipments [1].
High strength, cogging difficulties, and prone to cracking phenomenon in the process of plates rolling have seriously affected the yield and cost of materials; and because of its smaller yield ratio, higher elongation, improved heat treatment technics need be guaranteed [2].
It is mainly because with increasing deformation temperature, thermal activation function of the material enhances, and the average kinetic energy of atoms increases, and the critical shear stress caused by sliding crystals decreases, and dislocation movement and obstacles against the slip between crystal planes reduce [5,6], and with increasing temperature, dynamic recovery and dynamic recrystallization become more easier, which make dislocation density decrease, and offset hardening caused by plastic deformation, thereby reducing material flow stress.

Introduction GaN-based materials has attracted much attention for applications in high frequency, high efficiency, high-power and anti-irradiation microwave electronic devices due to its outstanding material properties such as wide band gap, high breakdown field, high electron saturation velocity, high sheet-carrier density, high electron mobility, strong anti-radiation, and superior chemical stability.
III-nitride materials are very promising candidates for microelectronic devices and have been quite attractive to the scientists since 1980s.
From then on, lots of universities, research institutions and corporations focused on the growth of GaN-based microelectronic materials and the development of high frequency and high power microwave devices.

Clay catalysts are interesting materials not only because of the low cost of their raw materials, but also because they are less harmful to the environment [4-10].
Materials and Methods Materials Green hard clay was purchased from Bentonisa, Boa-Vista region in Paraíba state, Brazil and the refined soybean oil was obtained from Soya.
Two the samples present type IV isotherms, characteristic of mainly mesoporous materials, with type H3 hysteresis loops, corresponding to slit-like pores [18].
Differential pore size distributions of the materials used in this study are illustrated in Fig. 2b.

Economic success of micro-systems technology requires cost-effective fabrication in large series as well as a great diversity of materials-processing technologies.
However, the production cost is very high in most cases, and the materials available are also limited.
Experimental materials and equipment In this study, submicron-sized zirconium powder mixed with 3mol% yttrium was used to prepare the feedstock, in which the water-soluble binder system consists of (30%PEG-4000+10%SA+30%PVB+30%EVA) and (30%PEG-8000+10%SA+30%PVB+30% EVA) components.
