【 摘 要 】

Present paper has the aim of establishing the plastic forming behaviour of the INCONEL 718 superalloy used for turbine engines. The experiments were realized in laboratory conditions, on a free falling dawn hammer, with high of free falling about H = 0.2 m, and the falling dawn mass about 71 kg. The determinations were made in the range of temperatures about 1100-1250°C, at every 50°C. Finally, the graphics of plastic forming versus temperature and mechanical working versus temperature were drawn. The final conclusion was that the optimum range of temperature for hot working of the INCONEL 718 alloy is 1150 ÷ 1250°C, in which the plastic forming resistance and specific hot working are optimum.
