Additively manufactured metallic materials exhibit excellent mechanical strength. However,
they often fail prematurely owing to external defects (pores and unmelted particles) that act …

For most safety-critical applications, the achievement of both high strength and high
toughness is one of the key requirements for structural materials. However, strength and …

An in-depth understanding of microstructure and resultant properties is paramount in the
design of a novel alloy system, especially for additive manufacturing (AM). The present …

The formation of balling, porosity and cracking defects is a vital obstacle in selective laser
melting of wrought Al alloys. However, it lacks systematic research on the origins of these …

Decreasing microstructural length scales to the nanoscale is a proven way of increasing
strength, but the intrinsic metastability of such structures typically makes them susceptible to …

Despite additive manufacturing processes are already widely used in several industrial
applications, there are few materials that are specifically designed and optimized for these …

To develop high-strength Al alloys for selective laser melting (SLM) additive manufacturing,
we designed a series of Al-Mg (-Si)-Sc-Zr alloys and additively manufactured them using …

Additive manufacturing of commercial materials designed for casting is challenging,
particularly for hot-crack-susceptible alloys. Adding Zr to Al alloys has a positive effect on …

Abstract 7xxx Al alloys such as Al-Zn-Mg-Cu are typical lightweight materials of excellent
mechanical performance. Their near-net-shape manufacturing by selective laser melting …

We describe and study the thermal profiles experienced by various age-hardenable alloys
during laser additive manufacturing (LAM), employing two different manufacturing …
