Hardenability is a mechanical feature of steel, which is extremely relevant for a wide range of steel applications and refers to the steel capability to improve its hardness following a heat treatment. In the proposed approach, a neural-network-based predictor of the so-called Jominy hardenability profile is exploited, and an optimization problem is formulated, where the optimization function allows taking into account both the desired accuracy in meeting the target Jominy profile and other constraint. The optimization is performed through genetic algorithms. Numerical results are presented and discussed, showing the efficiency of the proposed approach together with its flexibility and easy customization with respect to the user demands and production objectives.<\/jats:p>","DOI":"10.1007\/s00521-021-06242-w","type":"journal-article","created":{"date-parts":[[2021,7,2]],"date-time":"2021-07-02T11:07:16Z","timestamp":1625224036000},"page":"16451-16470","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Automatic steel grades design for Jominy profile achievement through neural networks and genetic algorithms"],"prefix":"10.1007","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6115-1588","authenticated-orcid":false,"given":"Marco","family":"Vannucci","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9574-0575","authenticated-orcid":false,"given":"Valentina","family":"Colla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,7,2]]},"reference":[{"key":"6242_CR1","doi-asserted-by":"publisher","DOI":"10.3390\/met10020288","author":"TA Branca","year":"2020","unstructured":"Branca TA, Fornai B, Colla V, Murri MM, Streppa E, Schr\u00f6der AJ (2020) The challenge of digitalization in the steel sector.
