Alüminyum Köpük Üretiminde Alüminyum Döküm Cürufu İlavesinin Mekanik Özelliklere ve Mikroyapıya Etkisi

Bu çalışmada, Al köpükler, 6063 Al alaşım döküm cürufu ve Borik asit kullanılarak üretilmiştir. Köpük malzemeler 130 ºC’de 1 saat ve 550 ºC’de 3 saat sinterlenmiştir. Mikroyapı optik ve taramalı elektron mikroskoplarla (SEM) analiz edilmiştir. Basma mukavemeti basma test cihazıyla ölçülmüştür. Cüruf miktarının artmasıyla gözeneklilik % 34,8’den % 37,8’e, basma dayanımı 12,43 MPa’dan 20,25 MPa’a ve sertlik 98 HV’dan 115 HV’a artmıştır.

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

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.
