FEM study of extrusion complexity and dead metal zone
Cold extrusion Solid profiles Shape complexity
2009/12/3
Purpose: Quality of the extruded product and efficiency of the manufacturing process can be seriously affected by inconsistent metal flow through the extrusion die. Metal flow problems can also signif...
State of the art of metal reoxidation study of iron castings
Metallic alloys Metal reoxidation Oxygen activity measurement
2009/12/1
Purpose: Metal reoxidation causes a number of iron castings defects, particularly when pouring them in greensand
moulds. One of them is pinholes the occurrence of which is explained by several hypoth...
