Abstract
A method of manufacturing or repairing a turbine blade includes inserting an insert into the leading edge portion of the blade situate particularly adjacent the radially outer end of the turbine blade. The insert is made of a material different from the parent material of the blade and having a higehr carbon content to enable a piece of material to be satisfactorily hardened by heat treatment, the heat treatment being such that the portion of the insert adjoining the blade is not significantly hardened thereby minimizing or eliminating the likelihood of the formation of cracks in the insert during use of the turbine to which the blade is secured.
