This study compares flood and LN&#8322;-derived cryogenic N&#8322; gas-jet cooling during TC18 turning. Cryogenic cooling was associated with shallower visible deformation, retained near-surface hardening, and lower surface roughness across the tested feed rates, although comparisons were descriptive due to the lack of independent replication in machining.

Comparative Observations of Feed Rate and LN2-Derived Cryogenic N2 Gas-Jet Cooling on the Surface-Altered Layer of TC18 Titanium Alloy during Turning

Titanium alloys are difficult to machine because low thermal conductivity and affinity for cutting-tool materials concentrate heat and mechanical loading ...
