Effect of Aluminum Casting Dross Addition on Mechanical Properties and Microstructure in Aluminum Foam Production

Abstract

In the study, Al foams were produced using 6063 Al alloy casting dross and Boric acid. Foam materials were sintered at 130 ºC for 1 hour and at 550 ºC for 3 hours. The microstructure was analyzed with optical and scanning electron microscopes (SEM). Compression strength was measured with a compression tester. The porosity increased from 34.8% to 37.8%, the compressive strength increased from 12.43 MPa to 20.25 MPa, and the hardness increased from 98 HV to 115 HV with increasing dross amount. © 2022, TUBITAK.
