The experiments were carried out at room temperature 30℃ and 15℃. The state of palm olein at 30℃ is liquid but it becomes a solid state at 15℃ by crystallization. Paraffin mineral oil was tested for comparison of tribological performance of palm olein. The metal flow characteristic, velocity and effective strain in the deformation zone of billet were calculated by using visioplasticity method. The results show that low extrusion load, increment of relative velocity and effective strain along the sliding plane of billet can be achieved by applying palm olein, which mean it is capable to reduce frictional constraint between tool and billet, in comparison with paraffin mineral oil.}, pages = {7--13}, title = {平面ひずみ押出し加工実験によるパーム油の潤滑特性の検討}, volume = {47}, year = {2005} }
