Effect of Quenching Water Temperature on Mechanical Properties of ZL101A

Abstract:

Taking ZL101A alloy as the research object, the ZL101A alloy test bar was solution treated at 535°C and kept for 5 hours, and then quenched at 25°C, 50°C, 70°C, 90°C water temperature conditions. And then aging the quenched alloy sample at 150°C and heat preservation for 3.5h. After tensile test, Brinell hardness test, using metallographic microscope, scanning electron microscope to observe the metallographic structure, fracture morphology and other methods of analysis, and summarized the changes in the structure and properties of ZL101A alloy under different quenching water temperature conditions. The results show that the elongation, reduction of area, and tensile strength of ZL101A alloy quenched at 70°C are the highest, and the Brinell hardness is the highest when the quenching water temperature is 25°C. Comprehensive practical application, the comprehensive mechanical properties of ZL101A alloy quenched at 70°C are the best.
