materials science and engineering<\/a> at the University of Wisconsin-Madison, investigating ways to develop strong, durable and robust high-performance metals.<\/p>\n\n\n\nOh completed his PhD at Seoul National University before taking a position as a postdoctoral researcher at MIT in 2018. During his PhD, he studied metallic glass and high entropy alloys. Typically, the properties of these alloys are tuned by trial and error. But Oh was able to develop some general rules on how to mix them to create high-strength metals.<\/p>\n\n\n\n
At MIT, he continued studying high entropy alloys and also researched the composition and microstructure of commercial steel, which he plans to continue investigating in Madison.<\/p>\n\n\n\n
\u201cMetal is the backbone of modern industry. There is a lot of demand for high-performance metals with high durability, light weight and other properties. And this affects sustainability,\u201d says Oh. \u201cThat\u2019s because the more elements we use to achieve these properties, the more complex the metals become. And that makes it hard to recycle because of the impurities.\u201d<\/p>\n\n\n\n
The production of steel is one of the largest contributors of carbon emissions, accounting for about 8% of the global total. Aluminum recycling, on the other hand requires only 5% of the energy used for producing new aluminum.<\/p>\n\n\n\n
\u201cOne of the ultimate targets of my research is to develop microstructures in metals robust enough to be insensitive to impurities or to processing,\u201d he says. \u201cSo, we want to make recycled metals competitive with metals created from their ore.\u201d<\/p>\n\n\n\n
An experimentalist, Oh will use UW-Madison\u2019s metallurgy resources to synthesize these metals. He plans to characterize them using various types of in-situ microscopy techniques as well as the synchrotron at Argonne National Laboratory. He hopes to study these metals at the atomic and nanoscale and look in particular at how extremely small clusters of elements that form in the metals affect their properties and phase transformations.<\/p>\n\n\n\n
Oh says UW-Madison\u2019s materials science and engineering department is an ideal place to study metals since it has a deep expertise in metallurgy, strong data science and materials modeling capabilities, and many experts in microscopy and materials characterization. \u201cWe will develop metals with many different properties and microstructures for different applications,\u201d he says. \u201cI’m very interested in collaborating with all these people.\u201d<\/p>\n","protected":false},"author":106,"featured_media":78932,"template":"","meta":{"_acf_changed":false,"_tec_requires_first_save":true,"_mbp_gutenberg_autopost":false,"_EventAllDay":false,"_EventTimezone":"","_EventStartDate":"","_EventEndDate":"","_EventStartDateUTC":"","_EventEndDateUTC":"","_EventShowMap":false,"_EventShowMapLink":false,"_EventURL":"","_EventCost":"","_EventCostDescription":"","_EventCurrencySymbol":"","_EventCurrencyCode":"","_EventCurrencyPosition":"","_EventDateTimeSeparator":"","_EventTimeRangeSeparator":"","_EventOrganizerID":[],"_EventVenueID":[0],"_OrganizerEmail":"","_OrganizerPhone":"","_OrganizerWebsite":"","_VenueAddress":"","_VenueCity":"","_VenueCountry":"","_VenueProvince":"","_VenueState":"","_VenueZip":"","_VenuePhone":"","_VenueURL":"","_VenueStateProvince":"","_VenueLat":"","_VenueLng":"","_VenueShowMap":false,"_VenueShowMapLink":false,"_tribe_blocks_recurrence_rules":"","_tribe_blocks_recurrence_description":"","_tribe_blocks_recurrence_exclusions":"","footnotes":""},"department":[2391],"focus_area":[2399],"news_category":[37],"news_tag":[],"class_list":["post-78543","news","type-news","status-publish","has-post-thumbnail","hentry","department-materials-science-engineering","focus_area-advanced-materials-design-and-manufacturing","news_category-faculty"],"acf":[],"_links":{"self":[{"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/news\/78543","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/types\/news"}],"author":[{"embeddable":true,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/users\/106"}],"version-history":[{"count":1,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/news\/78543\/revisions"}],"predecessor-version":[{"id":78549,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/news\/78543\/revisions\/78549"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/media\/78932"}],"wp:attachment":[{"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/media?parent=78543"}],"wp:term":[{"taxonomy":"department","embeddable":true,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/department?post=78543"},{"taxonomy":"focus_area","embeddable":true,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/focus_area?post=78543"},{"taxonomy":"news_category","embeddable":true,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/news_category?post=78543"},{"taxonomy":"news_tag","embeddable":true,"href":"https:\/\/engineering.wisc.edu\/wp-json\/wp\/v2\/news_tag?post=78543"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
