The influence of zirconium on the grain refinement of Al 6063 alloy has been experimentally investigated. The microstructure and macrostructure of the refined alloy were investigated. The experimental results reveal that, the coarse dendrites in the microstructure of the alloy are effectively refined with the addition of zirconium to the melt prior to solidification. Grains of Al 6063 alloy can...

Abstract Aluminium alloys (AA) are ubiquitous materials in manufacturing used powder bed fusion (PBF) processes due to light weight, high strength and corrosion resistance. Current research focuses on other whilst additively manufactured AA 7050 remains unexplored. This paper examines the formability of 7050-T7451 for Selective Laser Melting (SLM) process. To define this material Simufact Addit...

A study was carried out on the aging behaviour of a solution treated 6082 aluminium alloy deformed by equal channel angular pressing up to six passes. Aging of the so obtained ultrafine alloy was studied by DSC and TEM analyses as well as by isothermal treatments at 130, 160 and 180 C. The results showed that the formation of metastable 00 and 0 precipitates were markedly anticipated and that t...
