About Leandro

Dr. Leandro Bolzoni joined the School of Engineering of The University of Waikato as a senior lecturer in July 2015, and is leading the development and commercialisation of titanium based products obtained via thermomechanical powder consolidation (TPC). Dr. Leandro Bolzoni got his BS and MS in Mechanical Engineering at the Polytechnic of Turin in Italy, where he is originally from. In 2006 he moved to Spain to the Universidad Carlos III de Madrid where he received an MS in Materials Science and Engineering and was awarded his Doctorate in Materials Science and Engineering for the Ph.D. thesis titled “Development and Processing of Titanium Based Alloys Produced by Advanced Powder Metallurgy Techniques”. Before joining The University of Waikato, Dr. Leandro Bolzoni spent the previous three years at Brunel University London working on the development or reliable and efficient grain refiners for Al-Si cast alloys.

Research Interests

As the quote of the great inventor Leonardo Da Vinci states “Nessuno effetto è in natura sanza ragione; intendi la ragione e non ti bisogna sperienza”, in nature there is always a reason for each effect. This fits well for the world of materials science and it is especially true in the case of physical metallurgy of light metals, my main research field, where relatively little variation in terms of composition and/or processing can lead to completely different behaviours of the starting material. In particular, I am interested in the development and/or improvement of light metals such as titanium, aluminium and magnesium via non-traditional fabrication methods. In a world where the main structural metal has mainly been steel since the industrial revolution, the understanding of the nature and behaviour of the light metals is becoming paramount because of some of their intrinsic advantages, like the lightweighting effect and its related aspects such as higher performances, reduction of greenhouse emission and environmental friendly nature.  Further developments in the understanding and application of light metals can come from both the modification of the material itself as well as through the design of novel production routes. A clear example is the implementation of "additive manufacturing", others near-net-shape techniques, which is revolutionising the industrial world because the components or products are, actually, built layer-by-layer from an engineered drawing rather than obtained by the removal of materials by means of sophisticated and, sometimes, difficult-to-perform machining operations with noticeable advantages among which more freedom in the design of complex products and saving material and fabrication costs.
