AMI in association with the SAIMM are hosting the

27–29 October 2010
Misty Hills, Muldersdrift

The Advanced Metals Initiative (AMI), supported by the South African Department of Science and Technology, facilitates research, development and innovation across the whole value chain in the field of advanced metals, with the goal of achieving optimal sustainable local manufacturing of value-added products. Its objective is to increase the downstream value-addition of local advanced metals in a sustainable manner through industry relevant research and development, technology transfer, and ultimately, commercialisation.

The four legs of the AMI are Light Metals (Titanium, Aluminium & Magnesium), Precious Metals (Gold & the Platinum Group Metals (PGMs)), New Metals (Zirconium, Tantalum, Niobium & Hafnium) and Ferrous and Base Metals.

The AMI Light Metals Conference 2010 aims to bring together researchers, industry, and government stakeholders to share and debate the latest trends, research and innovative solutions in the field of light metals. It is intended to provide a forum for researchers and industry players to present the progress made over the past few years on the research and development, as well as application, of technologies for industrial applications of light metals.

Attendance includes stakeholders from the research and development community, private industry and academic institutions, both locally and abroad, providing to them a unique information sharing and networking opportunity.

On 27 October 2010 the event kicks off with a Student Seminar covering the full scope of the AMI, including Light Metals, Precious Metals, New Metals and Ferrous & Base Metals. Students are encouraged to make the most of this opportunity to share their work with their peers and to grow their presentation skills.

On the evening of 27 October 2010 a Cocktail Reception Function will be held for all delegates to the Conference.

The Light Metals Conference 2010 formally starts on the morning of 28 October 2010 and runs through to the afternoon of 29 October 2010.

Call for papers

The host of the AMI Ligtht Metals Conference 2010, the CSIR, is pleased to invite you to submit papers on the latest research and development (R&D) related to light metals. Industry sectors of special interest for the application of light metals are:

Power generation
Chemical processing.

Papers could deal with R&D and technologies in areas such as primary metal production, metal powder processing,
advanced casting processes, joining, high performance machining, forming and forging. Supporting competences,
such as physical metallurgy, simulation and modelling, mechanical and physical property characterisation and
commercialisation could also be addressed.

The Conference is being organised by The Southern African Institute of Mining and Metallurgy, and papers are invited for the Conference.

Prospective authors are invited to submit titles and abstracts of their papers, in English. The abstracts should be no longer than 500 words and should be submitted to:
