Machinability and surface integrity of RR1000 nickel based superalloy

Research output: Contribution to journalArticle


Alloy development for gas turbine components has produced materials able to maintain strength and integrity at operating temperatures up to similar to 1050 degrees C. Next-generation RR1000 nickel-based superalloy reflects this philosophy, albeit at the expense of machinability. Experimental data for drilling showed flank wear when operating at 45 m/min to be
