Patent number: 10906100Abstract: A method for manufacturing and heat treating a component formed from an alloy or superalloy. The component may be part of a gas turbine engine, such as an airfoil of a gas turbine engine turbine, or a combustor fuel nozzle, that includes internal cooling passages. At least part of the component is formed from the alloy or superalloy using an additive manufacturing process. The method includes determining an incipient melting point range and a recrystallization temperature of the alloy or superalloy. The component is then heated to at least the recrystallization temperature and within the incipient melting point range for a predetermined time, and ultimately cooled.Type: GrantFiled: August 1, 2018Date of Patent: February 2, 2021Assignee: POWER SYSTEMS MFG., LLCInventors: Gregory Edwin Vogel, Jeremy Metternich, Edwin John Kawecki, Jacob Snyder

Patent number: 7278463Abstract: An investment casting pattern is formed by forming a metallic first core element including at least one recess. The first core element is engaged to at least a mating one of an element of the die and a second core element. The recess serves to retain the first core element relative to the mating one. The die is assembled and a sacrificial material is introduced to the die to at least partially embed the first core element. The recess may be pre-formed prior to cutting the first core element from a larger sheet of material.Type: GrantFiled: May 31, 2006Date of Patent: October 9, 2007Assignee: United Technologies CorporationInventors: Jacob A. Snyder, James T. Beals
