Key to recycling

~ Matheus A. Tunes ~ Leave a comment

From Montanuniversität Leoben: https://www.unileoben.ac.at/en/newsdetail/schluessel-zum-recycling For almost a century, commercial aluminum materials have been developed and optimized for high performance in specific applications within strict chemical confines of industrially established alloy classes. The requirements associated with sustainable lightweighting concepts call for new strategies that offer a broader property portfolio with a better trade-off between formability, achievable … Continue reading Key to recycling

Defying reductionism in aluminium alloys

~ Matheus A. Tunes ~ 2 Comments

Our work on the emergence of a new class of aluminium alloys -- the crossover alloys -- has been highlighted in the Acta Materialia's most downloaded articles! A throughout article led and written by Dr. Lukas Stemper showing how chemical complexity and synergy between different alloying elements is now defying almost 100 years of accumulated … Continue reading Defying reductionism in aluminium alloys

Ce nanoparticles as a corrosion inhibitor in Al 2xxx series alloys!

~ Matheus A. Tunes ~ Leave a comment

With great pleasure I am sharing to all of you the first paper performed in collaboration with the research group of Professor Hercílio de Melo in the field of corrosion of Al alloys 2xxx series. In this paper we report that Ce-containing nanoparticles -- when stuck to the inherent porous walls of anodized layers -- … Continue reading Ce nanoparticles as a corrosion inhibitor in Al 2xxx series alloys!

Cutting edge Aluminium metallurgy!

~ Matheus A. Tunes ~ Leave a comment

Under the supervision of Professor Stefan Pogatscher and in collaboration with a strong scientific network, I am delighted to share our two "most fresh" papers pushing up the frontiers of Aluminium Metallurgy. The first "Age-hardening response of AlMgZn alloys with Cu and Ag additions" is a comprehensive assessment on the heat-treatment response and mechanical properties … Continue reading Cutting edge Aluminium metallurgy!

A giant leap on the fundamental phenomenon of age-hardening in aluminium alloys!

~ Matheus A. Tunes ~ Leave a comment

SIZE DEPENDENT AGE-HARDENING DISCOVERED!  The Montanuniversitaet Leoben has a small breakthrough to report. The age-hardening of metals was discovered at the beginning of the twentieth century. 110 years later, Phillip Dumitraschkewitz was able to show in his doctoral thesis under supervision of Professor Pogatscher from the Chair of Nonferrous Metallurgy, that the effect depends on the material … Continue reading A giant leap on the fundamental phenomenon of age-hardening in aluminium alloys!
