Effect of Cryogenic Treatment on Compressive Properties of Aluminum Bronze

Abstract

The microstructure, compressive fracture morphology and compressive strength of aluminum bronze before and after cryogenic treatment were observed and measured by OM, SEM and electron universal testing machine, and the effect of cryogenic treatment on compressive properties of aluminum bronze were investigated. The results show that cryogenic treatment can reduce the compressive strength of aluminum bronze, and after cryogenic treatment and at 600°C for 5min, its compressive strength is increased. And the microstructure of aluminum bronze has a good correspondence with its compressive strength.

Experimental Study and Analysis of the Dynamic Mechanical Properties of Aluminium Bronze

“…Therefore, there is a higher requirement for its dynamic mechanical properties. At present, extensive studies on aluminum bronze have primarily focused on alloy smelting, performance testing [1] and [2] and the influence of alloying treatment [3] and [4], or heat treatment [5] and [6] on microstructure [7] and properties [8]. However, less research has been done on the constitutive relation for QAL9-4.…”
