1. Study of precipitation in martensitic Fe-C-Cr alloys during tempering : Experiments and modelling
Abstract : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. READ MORE

2. Experimental study and simulation of sintering of 316L components produced by binder jetting
Abstract : Binder Jetting (BJT) is a multi-step Additive Manufacturing (AM) technique that is used for producing components with highly complex geometries and competitive final properties with high productivity when compared to other AM technologies. The first step provides the basic part geometric shape (BJT printing), and the next step (debinding and sintering) consolidates the part to reach final geometry and intended basic material properties.

3. Defects and Surfaces and their Impact on Fatigue Behaviour of Powder Bed Fused Ti-6Al-4V : Characteristics and Modelling
Abstract : Additive manufacturing (AM), of metals is gaining popularity as an alternative to conventional manufacturing techniques such as casting and forging. Metal-AM allows for the production of complex part geometries with reduced material waste and shorter lead times. READ MORE

4. Recovery of iron and manganese values from metallurgical slags by the oxidation route
Abstract : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. READ MORE

5. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport
Abstract : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. READ MORE
