Dependence of material characteristics on lubrication in bulk forming process
Leo Gusel, 2009, objavljeni znanstveni prispevek na konferenci

Opis: In the paper the influence of coefficient of friction (lubricant) on different properties of cold formed material has been examined. Tensile tests, hardness measurements and electrical conductivity measurements were performed.In the frame of the experimental work the process of cold forward extrusion of a cylinder made from copper alloy was investigated. The specimens were extruded at four different lubricants coefficients of friction. The results have shown that use of different lubricators with different coefficients of friction can have effects on the material properties during and after cold forming process.
Ključne besede: lubrication, cold forming, copper alloy, mechanical properties
