This white paper investigates the effect of solution heat treatment as well as primary and secondary aging treatment conditions on the microstructural evolution of a high-entropy superalloy.

There are 19 such centers across the nation. Each of them addresses research of a scope and complexity requiring the scale, synergy and research talent provided by a campus-based research center. The MRSECs essentially support the materials research infrastructure in the United States; promote collaboration between universities, industry and international organizations; and contribute to the development of a national network of university-based centers in materials research, education and facilities.

Aubert & Duval, a French producer of superalloys, high-performance steels, aluminum and titanium alloys in the form of bars, powders and forgings, created a new heat-treatment line. The line, which will completely replace the company’s current heat-treatment line 3, has been designed to achieve the following objectives: reduction of safety risks and improvement of working conditions; process and quality control; productivity and flexibility; and reduction of environmental footprint. Almost all the parts produced at Aubert & Duval’s Pamiers’ facility undergo heat treatment. Mastering these processes is central to the company’s industrial mission, which involves working on the most demanding projects in the aerospace, energy and defense industries.

Researchers at Oak Ridge National Laboratory (ORNL) demonstrated that a new class of superalloys made of cobalt and nickel remains crack-free and defect-resistant in extreme heat, making them conducive for use in metal-based 3D-printing applications. In a study, researchers processed the cobalt and nickel class of superalloys and proved that they remained crack-free in electron-beam and laser-melting 3D-printing processes. According to ORNL, the superalloys have the material properties necessary for challenging environments because they successfully withstood the heat and also retained strength when stretched.

Ametek Inc. signed a definitive agreement for the sale of its Reading Alloys business to Kymera International, a specialty materials company owned by affiliates of Palladium Equity Partners. Founded in 1953, Reading Alloys provides highly engineered materials for mission-critical applications in the aerospace, defense, medical and industrial markets. The company’s products include master alloys, thermal-barrier coatings and titanium powders.

The heat treatment and performance of high-temperature superalloys, and Inconel® 718 in particular, has always been of interest to The Doctor.

Ambrell sold an EKOHEAT 45-kW/100-kHz induction heating system to a large university for superalloyresearch.
