The Corrosion Characteristics of Additively Manufactured Austenitic Stainless Steel

There is a significant interest in industry for taking up Additive Manufacturing (AM) processes due to their advantages in producing customised 3D parts in one step, reducing both time and cost. Stainless Steels (SS), the mostly-used metal in corrosive environments, are a favoured material to produce in AM due to their widespread applications across many industries. However, there remain doubts in how AM SS would compete with their conventionally-produced counterparts in terms of meeting the minimum requirements for industrial applications. Majid Laleh's research highlights important aspects of localised corrosion characteristics in AM SS and revealed a method to produce high-density AM parts with none of the "Lack of Fusion" pores that invite damaging corrosion processes. These have a high potential to replace conventionally-produced SS in industries where high pitting corrosion and intergranular corrosion resistance are of high importance.

Majid Laleh is a final year PhD candidate with the School of Engineering at Deakin University. This presentation on "Microstructure and Localised Corrosion Characteristics of Additively Manufactured Austenitic Stainless Steel" comprises his entry to the Physical Sciences category of the Young Scientist Research Prizes in 2020, an annual competition conducted by the Royal Society of Victoria during National Science Week in Australia. Majid is the Second Prize winner in this category.

Due to Stage Four lockdown conditions in Victoria in response to the COVID-19 pandemic, this presentation was necessarily filmed on 13 August, 2020 and presented to judges at the Royal Society of Victoria on the evening 19 August, 2020, both via video conference.; due to the constraints of available recording technology, the resolution and audio in this presentation is at times less than ideal. We have provided subtitles to assist the viewer and recommend you switch these on in your YouTube settings.
