Annealing effect on mechanical properties of Ti51Ni13Pd36 high temperature memory alloy

Huibin XU , Shuqiang HU , Chengbao JIANG , Shengkai GONG

材料科学技术（英文）

The high temperature shape memory alloy Ti51Ni13Pd36 was subjected to a cold working and annealing treatment to improve its mechanical properties and the shape memory effect. It was found that recovery of the cold worked alloys started at near 673 K and the recrystallization temperature was at about...

Oxidation and Hot Corrosion of Gradient Thermal Barrier Coatings Prepared by EB-PVD

Hongbo GUO , Shengkai GONG , Huibin XU

材料科学技术（英文）

The performances of gradient thermal barrier coatings (GTBCs) produced by EB-PVD were evaluated by isothermal oxidation and cyclic hot corrosion (HTHC) tests. Compared with conventional two-layered TBCs, the GTBCs exhibite better resistance to not only oxidation but also hot-corrosion. A dense Al2O3...

Influence of Annealing on the Grain Growth and Thermal Diffusivity of Nanostructured YSZ Thermal Barrier Coating

Na WANG , Chungen ZHOU , Shengkai GONG

材料科学技术（英文）

The nanostructured zirconia coatings were deposited by atmospherically plasma spraying. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction were used to investigate the microstructure of the zirconia coatings. Thermal diffusivity values at normal temperat...
