The effect of lubricant with three different viscosities was investigated by plane strain extrusion experiments and visioplasticity analyses. The lubricant is additive free paraffinic mineral oil. VG30 is a low viscosity lubricant with kinematic viscosity of 32 mm 2 /s at 40ºC. VG95 is a medium vi...
