The Advanced Alloys Manufacturing Center

The Advanced Alloys Manufactuting Center has been established through the intermediary of the Central Anatolia Development Agency (ORAN) and within the scope of the Attraction Centers Support Program (CMDP) of the Ministry of Industry and Technology.

After the protocol signed in 2020, the works were initiated in March 2022.

While Advanced Alloy Manufacturing Center continues its R&D studies, it also provides practical training opportunities for our students.

It has a capacity of 25 kg and can operate at a high vacuum level.

It enables the melting/casting of advanced alloys.

Precise casting and ingot production can be carried out.

The melting capacity is 25 kg.

The system is suitable for powder production from materials/alloys that require a vacuum environment during the melting process.

These metal powders are then used in 3D printing for the production of various components using additive manufacturing method. In addition to being part of an integrated production, these three units can also directly market their own products.

SLM (Selective Laser Melting) is an additive manufacturing method where a laser is used to selectively melt and fuse metal powders to create complex 3D objects layer by layer.

The layer thickness used is typically in the range of 20-50 µm, and in terms of production quality, it surpasses competing metal additive manufacturing technologies.

Our device has a power capacity of up to 500 W, and the diameter of the production table is 130 mm.

Rapid Solidification Laboratory

As is well known, the rapid solidification process allows the liquid metal to cool at a rate of about 106 °C/s. As shown in the picture below, the solidification process takes place at extraordinary speeds by spraying liquid metal onto a rapidly rotating copper disk. In this way, the atoms can solidify in an amorphous form before they have time to form a crystal structure.

Amorphous metals are called metallic glasses and are characterized by their extraordinary properties. In addition, by expanding the limits of solid solubility, it is possible to create much newer alloys through the process of rapid solidification.

The superior corrosion, mechanical and some physical properties of these alloys can be far superior to their counterparts. For example, the mechanical properties of rapidly solidified aluminum alloys are twice as high as pyrometallurgical ingots.

All these rapid solidification processes are carried out in the Vacuum Induction Melting and Melt Spinning device, which we call VIEMS, in our laboratory.

The production and development of NdFeB based magnets, high strength Al alloys, Fe-Ni alloys and soft magnetic materials are carried out in this laboratory.

Future research will include the development of anisotropic NdFeB magnets that exhibit stronger magnet properties, the development of soft magnetic materials with better electromagnetic shielding, and the development of alloys that offer high strength and low thermal expansion.
