Experimental Tests for Cross Wedge Rolling of Forgings Made from Non-Ferrous Metal Alloys / Próby Doświadczalne Walcowania Poprzeczno-Klinowego Odkuwek Ze Stopów Metali Nieżelaznych

Reported in this paper are the experimental test results for hot cross wedge rolling of elementary shaft forgings made from light metal alloys which are widely used in aviation industry, such as aluminum alloys 6101A and 2618A, titanium alloy Ti6Al4V as well as magnesium alloys AZ31 (Mg 3Al-1Zn-Mn), AZ61 (Mg 6Al-1Zn-Mn) and Mg4AlZnMn. The research works were conducted by means of a flat-wedge rolling mill LUW-2, with typical wedge tools used. The experiment tests involved the analysis of force parameters, geometrical parameters, and process stability. The conducted experimental tests prove the feasibility of forming axially symmetric parts made from light metal alloys in CWR (cross wedge rolling) processes. Limitations upon the application of CWR technologies to forming such alloys are also described.
