Researchers use DSC to measure the energy changes (heat flow) in OFHC copper as it is heated or cooled. This reveals critical transition points like the recrystallization onset temperature and the deformation stored energy .

OFHC copper (ASTM/SAE grades C10100 or C10200) is highly valued for its electrical conductivity (up to 101% IACS) and thermal conductivity (

Research using this data often explores how severe plastic deformation (e.g., through wire drawing or extrusion) affects copper's thermal stability. For instance, studies have shown that cold-worked copper can soften at temperatures as low as 200∘C200 raised to the composed with power C due to its low recrystallization temperature.
