Abstract

Bu çalışmada, toz metalürjisi yöntemi kullanılarak ağırlıkça %50 boşluk oluşturucu olarak borik asit (H3BO3) ilavesiyle üretilen saf Zn ve Zn alaşımı (ZA27) köpük malzemelerin, makro yapısal ve mikro yapısal karakterizasyonu yanı sıra basma mukavemetleri araştırılmıştır. Köpük malzemelerden saf Zn köpükler, 300, 420 ve 630 MPa'lık farklı basınçlarda, Zn alaşımı köpük malzemeleri 630 MPa basınçta preslenmiş ve 70 dk boyunca 350 ° C'de sinterlenerek elde edilmişlerdir. Bu köpüklerden başarılı olarak elde edilen köpük malzemelerin 0.5 mm/dk basma hızındaki mekanik davranışları incelenmiştir. Sonuçlar, ZA27 alaşımı köpük malzeme için akma geriliminin ve plato geriliminin sırasıyla 7 MPa ve 6 MPa aralığında olduğunu göstermektedir. %40 ve %46 gözeneklilik içeren saf Zn ve ZA27 alaşımı köpük numuneleri 85 μm ve 600 μm ortalama hücre boyutlarıyla başarıyla üretilmiştir. Köpük numunelerdeki fazların morfolojisi ve kimyasal bileşimi, Taramalı Elektron Mikroskopisi (SEM), Enerji Dağılımlı X-ışını Spektroskopisi (EDX) ve X-ışını kırınımı (XRD) kullanılarak araştırılmıştır.

Investigation of the Compressive Behaviours of Pure Zinc and Zinc Alloy (ZA27) Foam Materials Produced Using Boric Acid (H3BO3)

Abstract

In this study, the macrostructural and microstructural characterization as well as compressive strength of pure Zn and Zn alloy (ZA27) foam materials produced by the addition of 50% boric acid (H3BO3) as a space holder by powder metallurgy method were investigated. Pure Zn foams were pressed at different pressures of 300, 420 and 630 MPa and Zn alloy foam materials pressed at 630 MPa pressure and both pure Zn and Zn alloy foam materials were sintered at 350 ° C for 70 minutes. The mechanical behaviors of the foam materials obtained successfully from these foams were investigated at a compression rate of 0,5 mm/min. The results show that for the ZA27 alloy foam material, the yield stress and plateau stress are in the range of 7 MPa and 6 MPa, respectively. Pure Zn and ZA27 alloy foam samples containing 40% and 46% porosity were successfully produced with average cell sizes of 85 μm and 600 μm, respectively. The morphology and chemical composition of the phases in the foam samples were investigated using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and X-ray diffraction (XRD).
