Patent number: 11548107Abstract: Methods of inducing segmented flow in a material in which a ductile flow mode would otherwise occur during machining. A monolayer molecular film is formed on a surface of a body of a material in a state such that the material exhibits ductile flow when subjected to shear. The monolayer molecular film has molecules each having a head group adsorbed to the surface, a terminal group, and a hydrocarbon chain therebetween having a chain length of greater than 6. A surface portion of the body is removed by engaging the body with a tool in a contact region below the surface of the body and moving the tool relative to the body to remove the surface portion and the monolayer molecular film thereon. The monolayer molecular film induces segmented flow in the material during the removing of the surface portion.Type: GrantFiled: November 6, 2020Date of Patent: January 10, 2023Assignee: Purdue Research FoundationInventors: Tatsuya Sugihara, Srinivasan Chandrasekar, Anirudh Udupa, Koushik Viswanathan, Kevin Paul Trumble, James Bradley Mann

Processes for producing continuous bulk forms of iron-silicon alloys and bulk forms produced thereby
Patent number: 11168377Abstract: Processes for producing continuous bulk forms of iron-silicon alloys and bulk forms produced thereby. Such a bulk form is continuous in a longitudinal direction thereof and has a continuous cross-sectional form transverse to the longitudinal direction. The bulk form is formed of an Fe—Si alloy and has a crystallographic texture that comprises <111> and {110} fibers that are inclined relative to the longitudinal direction. The bulk form may be produced by a process that includes deforming a solid body formed of an Fe—Si alloy with a cutting tool in a single step to continuously produce a continuous bulk form from material obtained from the solid body.Type: GrantFiled: July 29, 2019Date of Patent: November 9, 2021Assignee: Purdue Research FoundationInventors: Andrew Benjamin Kustas, Dinakur Sagapuram, Kevin Paul Trumble, Srinivasan Chandrasekar -

Patent number: 10843274Abstract: A method for controlling flow localization in machining process is disclosed. By application of a constraint of sufficient level in the deformation zone and modifying the surface boundary conditions, suppression of unsteady flow and flow instabilities is achieved. The method enhances machined component quality by ensuring a uniform deformation state on the machined surface. Machined components are produced by ensuing uniform deformation by adopting constrained-cutting process for suppressing the instabilities and unsteady flow through a pre-determined location of the constraint of the constrained machining process relative to the machining tool.Type: GrantFiled: July 17, 2015Date of Patent: November 24, 2020Assignee: Purdue Research FoundationInventors: Dinakar Sagapuram, Kevin Paul Trumble, Walter Dale Compton, Srinivasan Chandrasekar

Publication number: 20200188972Abstract: Processes for producing sheet metal products by machining a solid metal body with a cutting tool in a single step to continuously produce a continuous bulk form from material obtained from the solid metal body, and without performing a hot rolling operation thereon, cold rolling the continuous bulk form to produce a sheet metal product. The machining step is a large-strain machining process capable of being directly performed on an as-cast ingot or other solid body to produce a continuous intermediate product that can be directly cold rolled without any intervening hot rolling operation, and optionally without homogenization or annealing.Type: ApplicationFiled: November 12, 2019Publication date: June 18, 2020Inventors: Kevin Paul Trumble, Xiaolong Bai, Srinivasan Chandrasekar, James Mann

Patent number: 10507520Abstract: Processes are provided that include providing a copper-manganese alloy containing copper and manganese and having an amount of manganese that is at least 32 weight percent and not more than 40 weight percent of a combined total amount of the copper and manganese in the copper-manganese alloy, and casting the copper-manganese alloy by multidirectional solidification to produce a product in the form of a casting. The copper-manganese alloy has a composition sufficiently near the congruent melting point of the Cu—Mn alloy system to sufficiently avoid dendritic growth during the multidirectional solidification of the copper-manganese alloy to avoid the formation of microporosity attributable to dendritic growth. The product has a cast microstructure having a cellular and/or planar solidification structure free of dendritic growth and having multidirectional columnar grains.Type: GrantFiled: January 4, 2017Date of Patent: December 17, 2019Assignee: Purdue Research FoundationInventor: Kevin Paul Trumble
