Sažetak
This paper investigates the effect of heat treatment by cycling through 3 cycles at a temperature of 780 °C and maintaining at this temperature for 2 minutes with water cooling after each cycle. The tensile testing results confirmed the exceptional brittleness of the alloy after the second and third cycle, which was noticed by fractographic analyzes with a higher part of intergranular fracture and some transgranular type of fracture. However, after the first cycle alloys showed significant elasticity, that can be seen at fracture surface characteristic for plastic behavior of the alloy.
