Later on the optimized the optimized version of this alloy that comprises 12 wt. % Co, 6.8 wt. % Cr, 1.5 wt. % Mo, 4.9 wt. % W, 2.8 wt. % Re, 6.15 wt. % Al, 6.35 wt. % Ta, 1.5 wt. % Hf, 0.12 wt. % C, 0.015 wt. % B and 0.02 wt. % Zr became well-known as Rene 142 or R142 superalloy that has been widely used as welding material and structural material for a manufacturing of directionally solidified (DS) turbine blades due to unique combination of oxidation resistance and high mechanical properties that were achieved by the optimization of Ta+Al+Cr content coupled with no titanium addition and high aluminum content combined with the special multi step heat treatment, refer to per Earl W. Ross and Kevin S. O'Hara, "Rene 142: A high strength, oxidation resistant DS turbine airfoil alloy", Superalloys 1982, pp. 257 - 265. The optimization of rupture properties of Rene 142 DS as per Earl W. Ross and Kevin were achieve by a homogenization at 2335°F for 2 hours followed by annealing at 2050°F for four hours, primary aging at 1975°F for four hours and secondary aging at 1650°F for four hours (referred to as R142 HT).

Abstract: The present concept is a method of cladding and fusion welding of superalloys and includes the steps of firstly application of a composite filler powder that comprises 5- 50% by weight brazing powder which includes melting point depressants, and 50-95% by weight high temperature welding powder, to a superalloy base material. Secondly there is simultaneous heating of the base material and the composite filler powder by a welding heat source that is movable relative to the base material. There is heating to a temperature that will fully melt the brazing powder and at least partially melt the high temperature welding powder and also melt a surface layer of the base material, thereby forming a weld pool. Thirdly upon solidification and cooling of the weld pool, there is coalescence between a weld bead and the base material.
