Profile: Dr Yuman Zhu ARC Future Fellow

Dr Yuman Zhu is currently an ARC Future Fellow within the Department of Materials Science and Engineering at Monash University. He earned his Master’s degree from Tsinghua University in China and subsequently completed his PhD at Monash University. Following his doctoral studies, Dr Zhu embarked a rewarding trajectory as a research fellow, including an ARC DECRA fellowship.

In 2020, Dr Zhu assumed the pivotal role of Academic Manager at the Monash Centre for Additive Manufacturing (MCAM), later advancing to the position of Deputy Director of MCAM.

Dr Zhu’s current research focuses on the additive manufacturing of metallic materials, where he specialises in employing advanced microscopy techniques to probe the rapid solidification and phase transformations inherent in the additive manufacturing process. His primary objective is to establish the intricate relationships among processes, microstructures and mechanical properties, thereby advancing the application of additive manufacturing to new frontiers.

What are the big issues in your research area?

During my exploration of the prominent issues within my current research domain of additive manufacturing (or 3D printing), I am witnessing a notable paradigm shift from the mere process of 'how to print' to the more substantive emphasis of 'how to effectively utilize' printed materials. This evolution highlights the increasing significance of in-service performance of printed components, driving my latest research endeavours.

What do you think are your most significant research accomplishments?

A notable example of my efforts to align with this transformative trend is reflected in my ground-breaking research featured in the esteemed journal Nature Materials in 2022. This work reports on the development of a commercial titanium alloy through 3D printing, showcasing unprecedented strength surpassing that of nearly all other 3D printed alloys known to date due to the unique nanotwinned precipitates formed from the 3D printing process (left figure).

This achievement assumes heightened significance considering the pivotal role that titanium alloys play in metal 3D printing within the aerospace industry, aimed at enhancing fuel efficiency and reducing environmental impact. Building upon this milestone, my Future Fellowship project endeavours to delve deeper into the unique microstructure of commercial titanium alloys, aiming to unlock their full potential. By doing so, we seek to guarantee unparalleled in-service performance, particularly in demanding environments. This will pave the way for a considerable boost in the industrial acceptance of 3D-printed products.

How do you feel about translating research outcomes to industry?

As I navigate through the dynamic research terrain, I remain steadfast in my commitment to contribute to this transformative journey. My efforts are dedicated to addressing fundamental challenges and pushing the frontiers of additive manufacturing technology. By bridging the gap between academic inquiry and industrial application,

I aspire to facilitate the seamless integration of additive manufacturing solutions across diverse industrial sectors.

This research methodology builds on the ongoing pursuit of Monash Centre for Additive Manufacturing I am working in, which emphasises the critical role of translating research into innovation and harnessing applied research to address pressing societal challenges.

Drawing from our centre's prior successful experience, I am able to collaborate effectively with a diverse spectrum of industrial partners and consistently attract funding from the industry. A fundamental lesson gained from our collaborative ventures is the significance of understanding the authentic needs of the industry and seamlessly integrate them with the capabilities of our research team.

At the core of this success lies the ongoing commitment to research excellence, bolstered by an enhanced ability to meet evolving challenges.

What has been the most productive period in your research career and why?

Reflecting on my research journey, one particularly noteworthy phase of fruitful outcomes occurred during my ARC DECRA (Discovery Early-Career Research Award, 2017-2019). This fellowship afforded me an immersive research environment, allowing me to leverage my accumulated experience to delve deeply into the realm of light metals.

During this period, I successfully authored five papers in the prestigious metallurgical journal of Acta Materialia and collaborated on a paper published in Science. These achievements laid a robust foundation for my subsequent research ventures into the emerging field of metal 3D printing and working with the industrial partners.

If you were starting your project

•

• or research again today, what would you do differently?

For an early career researcher, I would place emphasis on embracing the many failures of research activities as an intrinsic aspect of the journey. By encountering setbacks early and learning from them, we can cultivate resilience and foster growth within the research community. This iterative process of learning from failures is pivotal in driving progress and innovation.

How do you balance your time?

In my current position, adept time management is essential as I navigate a multitude of tasks and responsibilities. As an academic, I believe it is crucial to devote sufficient time and focus to research, collaborative endeavours, and research management. This involves optimising productivity while also ensuring a sustainable work-life equilibrium.

How do you feel about teaching? What is your teaching philosophy?

Engaging in teaching and mentoring students hold profound significance for every academic. From my standpoint, fostering understanding, providing support and encouraging dynamic communications are crucial elements in igniting students' enthusiasm for learning.

Lastly, I really think passion is the key that drives us to explore new things, work together in different areas, and inspire the upcoming researchers and innovators. When we stick to these principles with full dedication, I'm pretty sure we can shape a brighter and more sustainable future through the transformative power of additive manufacturing.
