Review waiting, please be patient. This may take 8 weeks or more, since drafts are reviewed in no specific order. There are 1,807 pending submissions waiting for review. If the submission is accepted, then this page will be moved into the article space. If the submission is declined, then the reason will be posted here. In the meantime, you can continue to improve this submission by editing normally. Where to get help If you need help editing or submitting your draft, please ask us a question at the AfC Help Desk or get live help from experienced editors. These venues are only for help with editing and the submission process, not to get reviews. If you need feedback on your draft, or if the review is taking a lot of time, you can try asking for help on the talk page of a relevant WikiProject. Some WikiProjects are more active than others so a speedy reply is not guaranteed. How to improve a draft Wikipedia:Contributing to Wikipedia – a basic overview on how to edit Wikipedia. Help:Wikitext – how to use the markup Help:Referencing for beginners – how to include references Wikipedia:Article development – how to develop your article Wikipedia:Writing better articles – how to improve your article Wikipedia:Verifiability – make sure your article includes reliable third-party sources You can also browse Wikipedia:Featured articles and Wikipedia:Good articles to find examples of Wikipedia's best writing on topics similar to your proposed article. Improving your odds of a speedy review To improve your odds of a faster review, tag your draft with relevant WikiProject tags using the button below. This will let reviewers know a new draft has been submitted in their area of interest. For instance, if you wrote about a female astronomer, you would want to add the Biography, Astronomy, and Women scientists tags.

QuesTek Innovations LLC is a materials science, engineering and software company that develops materials for applications such as automotive and aerospace. It is one of the first companies to employ integrated computational material engineering (ICME), which relies on physics-based models to predict the performance characteristics of materials. QuesTek has developed materials for companies such as Tesla, SpaceX, Apple, General Motors, Audi,^[1] and government agencies such as NASA, United States Department of Energy, and United States Department of Defense.^[2] QuesTek uses simulation tools to predict formulations of alloys that can meet the requirements for material properties and performance, often while increasing sustainability.^[3]

QuesTek was founded in 1997 in Evanston, Illinois, by Greg Olson, Charlie Kuehmann, Ray Genellie and Charlie West. Olson is currently the chief science officer of QuesTek, a member of the company’s board and a professor at Massachusetts Institute of Technology. He is a former professor at Northwestern University.^[4]

QuesTek designs metal alloys for applications such as airplane parts, race-car gears, medical devices and sporting goods. It uses computer-modeling methods to complete work for clients such the U.S. Defense Department, Boeing and other original equipment manufacturers. QuesTek claims to be able to make new metal alloys in half the time and at less than 30% of the cost of traditional methods. QuesTek's software predicts how certain elements will react to one another and gets an early read on characteristics such as strength, flexibility and weight.^[5]

Kuehmann is now the vice president of materials engineering at SpaceX and Tesla and formerly worked on a design team at Apple. At Tesla he has overcome materials challenges related to stainless steel.^[6]

At MIT, Olson investigates fracture resistance, creates materials system designs through computational modeling, and develops design methodologies for alloy steels and other materials, including intermetallic composites, ceramics, and polymers. In addition to his role at MIT, he is currently chief science officer at QuesTek.^[7]

In 2023, QuesTek launched its Integrated Computational Materials Design (ICMD^®) software, which is built on computational physics models developed by QuesTek in order to resolve challenges from hundreds of materials science engagements QuesTek has completed on behalf of private companies and government agencies since 1997.^[8] Drawing on QuesTek’s proprietary models as well as the Materials Genome Initiative, ICMD^® maps materials science outcomes into predictive models.^[9] ICMD^® also uses AI and machine learning when beneficial to solving a particular materials challenge.^[10] The ICMD^® SaaS application developed by QuesTek allows users to bring ICME capabilities in-house, in order to develop, design and deploy novel materials.^[11]

QuesTek holds 25 patents and currently has 11 patents pending.^[4]

QuesTek developed heat-resistant rocket alloys for the SpaceX reusable launch system development program. Its materials were used on the Starship’s Super Heavy booster that landed back on the launchpad in October, 2024.^[12]

The U.S. Air Force uses QuesTek’s Ferrium® S53® steel on landing gear pistons of the T-38 aircraft. This steel provides resistance to stress corrosion cracking, fatigue, corrosion fatigue, and grinding burn damage. It also eliminates the need for toxic cadmium plating.^[13]

QuesTek also worked with the U.S. Navy to find a new alloy for the hook shank on Navy aircraft. QuesTek developed Ferrium® M54® steel, which is lower cost, stronger and corrosion resistant, doubling the number of landings before replacement is needed to 2,000. Ferrium® M54® also does not use cobalt, which is sourced from countries in Africa which can be unstable.^[14] The National Institute of Standards and ­Technology (NIST) also supported the development of Ferrium® M54® as one of several Quantitative Benchmark for Time to Market Framework case ­studies to support the Materials Genome Initiative.^[15]
