Austenite stabilization at room temperature in medium Mn DP steels through CPPT

The presence of retained austenite (RA) has been proven beneficial for the formability of Advanced High Strength Steels. Therefore, multiple thermal austenite stabilization methods have been researched, such as Mn-partitioning during intercritical annealing in medium Mn steels. The Cyclic Partial Phase Transformation (CPPT) approach has been...

Alginate-based copolymers as the solid-state electrolyte for Mg battery

The high theoretical volumetric capacity, abundance of magnesium in the earth’s crust, and the relatively good safety features of Mg metal, have drawn great attention to developing Magnesium batteries as a follow-up to the success of Li-ion battery technology. However, the magnesium metal is incompatible with most electrolyte solvents and salts,...

The lignocellulose binding phenomena and interlaminar fracture toughness of living Ganoderma lucidum

Mycelium based composites (MBC) have revolutionised the field of material production, where a living fungus is employed to overgrow and bind lignocellulosic substrate materials together. Their bio-based nature, low embodied energy, and biodegradability, mark their great potential to reduce the increasing pressure conventional materials put on...

Correlating laboratory tests with service life performance of marine coating systems

Accelerated tests have been commonly used by the marine coating industry to evaluate the performance of a coating in a short duration of time. Replicating natural exposure in an artifi- cially simulated manner is a challenging task due to the various factors that induce corrosion in the natural environment. Continuous salt spray testing is a...

Short-time Oxidation of Fe-Mn Alloys

The global production of steel in a year is in the range of several millions of tonnes due to its essential function in industries such as automotive, manufacturing, and construction among others. However, a major challenge faced by the steel industry in the development of new steel grades is the inability to predict surface behaviour, such as...

Processability and Characterisation of Innovative Materials for Cutting Elements

Essential criteria to a shaving blade include wear resistance, corrosion resistance and a sharp cutting edge. The material selection for improved cutting elements as well as increasing the longevity of the blade would provide benefits not only to the consumer experience of a more efficient shaving performance, but also a more sustainable...

Influence of Quenching Temperature and Mn Content on the Microstructure Development of New Q&P Processed Martensitic Stainless Steels

Quenching and Partitioning (Q&P) is a novel steel heat treatment to create microstructures containing martensite and retained austenite. In recent years, there has been a growing interest in applying Q&P treatments to martensitic stainless steels with the aim to create stainless steels with the mechanical properties...

Fatigue Life Evaluation and Prediction of Inconel 718 Manufactured by Selective Laser Melting

The prevalence of additive manufacturing (AM), or 3D printing, has grown in recent decades as a method of manufacturing complex geometries, prototype parts, or high tuned microstructures. One method of additive manufacturing is selective laser melting (SLM), a powder bed fusion technique which utilizes a laser to melt a metal alloy powder layer...

Study of n-type Amorphous Silicon Alloy as the Anode in Li-ion Batteries

In recent years, the world has witnessed a dramatic advancement in sustainable energy development. Due to the inconsistent supply of such energy, a more efficient energy storage method is in need. Among many options, lithium-ion battery stands out due to its lightweight, high energy density, and high discharge potential. Currently, the most...

On the stability of cerium inhibiting layers on aluminium 2024-T3: an in situ optical and electrochemical study

Salts of trivalent cerium (Ce(III)) are known to successfully hinder localised corrosion phenomena typical of aerospace aluminium alloys by forming a thin passivation layer on top of the corrosion-active intermetallic phases. This is generally observed to happen when the alloy is under immersion conditions in a solution containing Ce3+ ions....

The effect of post process treatments on biomechanical properties of Ti6Al4V metamaterials and spinal cage implants manufactured by selective laser melting

Selective laser melting (SLM) is an additive manufacturing technique, which is currently on the rise of being used for manufacturing bone implants. Spinal cage, dental and hip implants can for example be manufactured using SLM. Ti6Al4V lattice structures, categorised as metamaterials, can be printed by SLM with mechanical properties close to...
