Studies the possibility on improving trursmutative soil service life based on the tungsten alloy cast iron liner which was made from tungsten slag alloy.

Tungsten alloy white cast iron(TAWCI)has a low cost,but the application is limited owing to its high brittleness.

The phosphorus-tungsten alloy cast iron would generate some white structure and mottled structure after standing its melt in high temperature.

Study of iron-tungsten alloy electroplating;

Development of alloy cast iron standard materials for spectral analysis;

The Cu-Ni alloy cast irons of different chemical constitution were designed,and the corrosion rate in room-temperature concentrated alkaline solution was measured by the static hydrometer method,the microscopics and phase composition of alloy cast iron were observed by optical microscope and XRD.

The corrosion rates of Cu-Ni alloy cast irons in hot concentrated alkaline solution were measured by dynamic condition hydrometer method,the microscopic structures and surface corrosion topographies of alloy cast irons were observed by the optical microscope and SEM,the components were analyzed by XES.

To study high-speed machining process of alloy cast-iron, a finite ele ment model (FEM) is built.
