Fe2O3-Al2O3 nanocomposite that combine ferrites and dielectrics to form a crystal structure can be used as an EM absorbing material since pure electric or magnetic materials are insufficient radiation energy absorbers [10].
Among the candidates for EM wave absorbing materials, the focus has recently fall onto soft magnets owing to their high saturation magnetization and magnetic anisotropy.
Soft ferrite materials as EM wave absorbing materials have been widely studied from megahertz (MHz) to GHz due to their strong magnetism and high electric resistivity [11, 12].

The term is used in multiple fields including ceramics, metallurgy, materials, manufacturing, earth sciences and construction.
Porosity is a measure of the void spaces in material, and is measured as a fraction, between 0 - 1, or as a percentage between 0 - 100 %.

Second phase particles precipitation behavior during deformation and cooling of T700 is researched rarely, which are this paper main research object. 1 Testing material and experiment scheme Experimental materials provided by a factory, tested with Gleeble-3500.
As holding time longer, numbers of precipitates gradually increase, but changing in size of precipitates is very small due to low temperature. 4 Acknowledgement Shanks for supporting Science and Technology Department of Hebei Province（12212122D）and The National Natural Science Foundation Project（51074062） References [1].

The primitive heat treated condition of GH4169 material is the direct aging treatment of metal after hot rolling, its organization is the austenite, and it distributes many second and the twin crystals in pellet, as shown in Fig.1.
From Fig.2 we can see that the de-noised signal eliminates material and background noise better, and has reappeared the material flaw characteristic well.
