Metal Additive Manufacturing Conference - MAMC 2022

Advances in Additive Manufacturing by powder bed fusion technologies based on EBM (Electron Beam Melting) or SLM (Selective Laser Melting) as well as other powder based additive routes such as LMD (Laser Metal Deposition) have led to an increase of demand on spherical powders [1]. However, most applications are realized through a handful of commercially available powders. Customized alloys and...

Aluminium alloys have a wide range of applications, specifically in the areas of aviation and aerospace. However, conventional manufacturing processes often limit the complexity of the fabricated parts. With the use of additive manufacturing techniques, near...

Metal additive manufacturing has developed and opened numerous fields of new components being used in aerospace, motorsports, automotive or light weight construction. The more challanges have been targeted, the more new powder materials were needed. Being among the lightest materials, Aluminum was always in scope for driving those projects. Especially from the moment also mechanical properties...

As the oil and gas companies seek to find sources of production in low-risk areas they are moving further offshore and deeper underwater. This has driven the demand for more corrosion-resistant materials, which are stronger and lighter than existing materials. Many of these materials, such as duplex and super duplex steels, martensitic stainless steels etc. are now widely used in conventional...

Maraging steels are a well-established material system for Additive Manufacturing (AM), especially for laser powder bed fusion (L-PBF), due to the high hardness & toughness produced by a martensitic aging heat treatment, which does not require carbon. Maraging steels have been successfully applied to L-PBF for conformal cooled tooling and tyre mould production. However, standard maraging...

In recent years, there has been much activity to develop a test to measure the quality of thin layers produced from metal powders, otherwise known as the property of spreadability. Several strategies have been published but no single test has yet been adopted by the powder metallurgy community. This study presents the development and testing of one such measurement technique that is simple,...

Nowadays, Copper alloys are widely used in additive manufacturing applications. Generally spoken, a higher thermal and electrical conductivity goes hand in and with a lower yield strength. Hence, a lot of efforts are being undertaken to improve mechanical properties of copper alloys, e.g. by improving dispersion strengthening or aging mechanisms, by chosing the right heat treatment and of...

The most widely used soft magnetic alloys are still legacy silicon steels, even in demanding applications such as modern electric car motors. The widespread use of amorphous and nanocrystalline alloys with far superior soft magnetic properties is hindered by size restrictions enforced by their standard manufacturing methods. The laser powder bed fusion method can produce amorphous or...

The development of new high-performance alloys is a key factor for innovation and technological advances. However, the conventional development route by means of casting is not designed to facilitate a high-throughput alloy development, since in general only one alloy composition can be made per cast and process inherent challenges like macrosegregations occur when dealing with highly alloyed...
