Effect of Different Heat Treatments on Microstructure and Mechanical Properties of Steel Containing Ni of 9% Base and Weld Metals

Abstract:

An comparative study was made of microstructure and mechanical properties of steel constaining Ni of 9% in different heat treatments. Shielded metal arc welding (SMAW) was employed as jointing technique. Double normalizing and tempering (NNT) and quenching, intercritical quenching and tempering (QLT) were applied as the heat treatments. Instrumented impact and tensile tests were performed between 20°C and 196°C. The results show that both the microstructure and mechanical properties of base and weld metals in QLT solution turn out to be the optimal.
