US Army introduces the new superalloy Mondaloy 200 for Rocket Engines (US)
"""
The sub-scale preburner test campaign accomplished the first demonstrations of several key rocket engine technologies, including the first use of Mondaloy 200 superalloy in a rocket engine environment and the first operation of a diluent type preburner. Demonstration of Mondaloy 200, which was co-developed by Aerojet Rocketdyne and the AFRL Materials Directorate, was a critical step to proving the unique combination of high-strength and burn resistance necessary for hardware survival in the harsh ORSC rocket environment. “These tests are a significant milestone for our program, but also just the beginning of an effort to develop and transition the tools, components and knowledge needed for our customer and the U.S. rocket industry,” said Dr. Shawn Phillips, chief of the AFRL Rocket Propulsion Division.

Hydrocarbon Boost (HCB)
"""
The three critical components are the ox-rich preburner (ORPB), turbopump assembly (TPA), and the thrust chamber assembly (TCA). The ORPB is a full flow combustion device that operates at a low 7 mixture ratio, close to stoichiometric. Downstream LOX diluent is injected into the hot gas to produce uniform temperature gas to the turbine. [...] incorporates Mondaloy 200™ to provide the high strength ox-resistant material.

[Monica] “Jacinto has developed and patented Mondaloy 100 and 200, which are burn resistant alloys for gaseous oxygen environment applications that greatly reduce the weight of the components over conventional materials used on previous engine development programs. Its properties allow space vehicles to be made thinner and lighter and remove the need for protective coatings. As a result, the vehicles have increased safety and reliability, and decreased cost.”

Burn-resistant metal alloys that also have a high tensile strength are described. The alloys generally include about 55 to about 75 weight percent nickel, about 12 to about 17 weight percent cobalt, about 4 to about 16 weight percent chromium, about 1 to about 4 weight percent aluminum, and about 1 to about 4 weight percent titanium.

Tribute to Dallis Hardwick (1950-2014)
"""
I decided to take a poll among my project team members and a few others within the company who had a vested interest. The overwhelming response was for the alloy name to be a combination of the names Dallis and Monica. I suggested to Dallis it should be Dalmonoy and she responded, "That does not sound as good as Mondaloy - let's name it that". It stuck and the two variants became Mondaloy 100 and Mondaloy 200. I think this was just Dallis being humble. I suspect she was as uncomfortable as I was to have an alloy named after oneself.
