As a potent grain refiner for steel casting, TiN is now widely used to refine γ-austenite in additive manufacturing (AM). However, the refining mechanism of during AM remains unclear despite intensive research recent years. This work aims boost our understanding on AM-fabricated 316 stainless and its corresponding effect mechanical behaviour. Experimental results show that addition 1 wt.% nanoparticles led complete columnar-to-equiaxed transition significant refinement austenite grains ∼2 µm...
Data-driven modelling, such as machine learning (ML), has great potential to streamline the complexity involved in designing new alloys. However, powerful predictive models require a high-quality dataset, which is limited alloy field due selection and reporting biases. These biases lead out-of-distribution (OOD) regions where ML suffer from performance degradation, limiting design of innovative To overcome this problem, we propose ML-based strategy for unique high-performance aluminium (Al)...
Over the last century, improvement in mechanical performance of structural metals has primarily been achieved by creating more and complex chemical compositions. Such compositional complexity raises costs, creates supply vulnerability, complicates recycling. As a relatively new metal processing technique, 3D-printing provides possibility to revisit simplify alloy compositions, achieving plainification, which enables simpler materials be used versatilely. Here, we demonstrate that high simple...
Abstract The effect of TiB 2 addition on microstructure refinement the as-cast and reheated A517 steel has been investigated. 0.1 wt.% resulted in a reduction equiaxed γ grain size from 990 ± 183 to 116 35 μm an increase volume fraction region 5% 67% ingots. Microstructure analysis identified TiN particles rather than . This is attributed low thermodynamic stability , leading its decomposition into free Ti B elements at elevated temperature. Then, chemical reaction between residual nitrogen...
