MICROSTRUCTURE EVOLUTION OF MG-GD-Y-ZN-ZR MAGNESIUM ALLOY DURING PARTIAL REMELTING

The article deals with the research on the microstructure evolution of Mg-Gd-Y-Zn-Zr magnesium alloy through partial generic baby picture remelting process.It aims at finding out what effects the microstructure of semi-solid Mg-Gd-Y-Zn-Zr alloy will result in under different remelting temperatures and holding times.Based on the results, if to miken

Transportation activities are stages in the product distribution system.The purpose of the transport system is to minimize the kotha model dress total cost.If there is more than one objective function and consider more than one type of vehicle, it is called a multiobjective solid transportation problem.In some cases, the parameter transportation mo
