Abstract

Al
2O3 and TiB2 particles have been successfully synthesized in aluminum matrix with in situ reactions
by hot pressing method. Process parameters; sintering temperatures 900-1000oC, pressure of cold pressing: 7 MPahot pressing: 1 MPa and holding times in furnace 5-10 minutes were selected. Composite microstructures and
reinforcement particle numbers-sizes were investigated via SEM and EDS analysis. According to the analysis
results; brittle Al3Ti intermetallic transition phase frequently encountered in the literature could be eliminated.

Abstract

Al
2O3 ve TiB2 partiküller, sıcak presleme yöntemi sayesinde in situ reaksiyonlarla alüminyum matris içinde
başarıyla sentezlenmişlerdir. İşlem parametreleri; sinterleme sıcaklığı 900-1000oC, soğuk presleme basıncı: 7 MPasıcak presleme basıncı: 1 MPa ve fırında bekletme süresi 5-10 dakika olarak seçilmiştir. Kompozit mikroyapıları ve
takviye partikül sayı-boyutları SEM ve EDS analizleri vasıtasıyla belirlenmiştir. Analiz sonuçlarına göre; literatürde
sıkça rastlanan gevrek Al3Ti intermetalik geçiş fazı elimine edilebilmiştir.
