Pengaruh Kadar Magnesium terhadap Ketangguhan Aluminium Alloy Foam yang Menggunakan CaCO3 sebagai Blowing Agent dengan Uji Impak dan Foto Mikro

Abstract

The process of makingaluminumfoamblowing agentwithCaCO3throughmeltmethodbasedlarge-scale processwithlessthanTiH2blowing agentwhich is a compoundgas producerthat has beenused commerciallyand has been widelyusedin the industry.With areview of the literaturerelated to thematerialpropertieson the detailsof cell structureintact. The purposeof this study to testthe impactandthe photographon aluminummagnesiummicrofoam.By addingmagnesium levelscan create multiplevariablesformagnesiumlevelscanalsoaffect the strength ofthe productas well asphysical properties.Conclusion Theresults ofthis study indicatethat the fewerthe betterlevels of magnesiumdistribution ofpores sothe small theenergy absorbed.Thenthe resultsofthe micropicturelooksthe addition ofmagnesiumto the aluminumfoammicrostructurewill result inaform ofdark blacklineshowsthe elementmagnesiumparticlesandgrayindicatesaluminum.As well asproductswith4%magnesiumlevelshavepore distributionorcellaluminumfoamevenlyspread, different levels of magnesiumproducts6%and 8% have unevenporesand just lookedatsome partsdo nothavepores.So alsowith the energyabsorptionofaluminummagnesiumfoamwith4%magnesiumlevelsare 12.4 Nm,6% is 15.94 Nmand 8% is16.54 Nm.
