Analysis of Cracks in the Pulsed Nd:YAG Laser Welded Joint of Nickel-Based Superalloy
The weldability of GTD-111 nickel-based superalloy by pulsed Nd:YAG laser welding with an average power of 250 W was studied, and the microstructural evolution and cracking characteristics were also investigated. The solidification cracking of the fusion zone (FZ) and the intergranular liquation cracking in the heat affected zone (HAZ) were observed in the joint. Solidification cracking was cau...
متن کاملLaser Cladding of Ultra-Thin Nickel-Based Superalloy Sheets
Laser cladding is a well-established process to apply coatings on metals. However, on substrates considerably thinner than 1 mm it is only rarely described in the literature. In this work 200 µm thin sheets of nickel-based superalloy 718 are coated with a powder of a cobalt-based alloy, Co-28Cr-9W-1.5Si, by laser cladding. The process window is very narrow, therefore, a precisely controlled Yb ...
متن کاملParametric optimization of powder mixed electrical discharge machining for nickel-based superalloy inconel-800 using response surface methodology
Background: Electrical Discharge Machining (EDM) is a well-established non-conventional machining process for the machining of electrically conductive and difficult-to-machine materials. But its applications are limited because of the slow machining rate and poor surface finish. Powder mixed EDM (PMEDM) is unitary of the recent progresses in the EDM process in which powder particles mixed in th...

the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...
Investigation into Grindability of Gh4169 Superalloy and Effects of Grinding Parameters on the Surface Integrity
GH4169, a nickel-base heat-resistant alloy, usually has outstanding high-temperature strength, excellent thermal stability and good wear resistance. However, it is hard to cut and its machined surface quality and integrity are particularly sensitive to a manufacturing process employed. The study reported in this paper was conducted to initially, review existing research on machining-induced sur...
