And the resource dependency for corporate diversification is analyzed by combining fuzzy comprehensive evaluation with grey multi-hierarchal synthetic evaluation model.

The deformation mechanism of the spray formed 70Si30A1 alloy was studied by hot compression on a Gleeble-1500 test machine. It is shown that hot deformation of the spray formed 70Si30Al alloy is achieved by liquid flow due to isostatic pressure and movement of solid particles due to shear force. Deformation condition depends on the nucleation rate and closure rate of the cavities. The flow stress...
