A Review on Superalloys and IN718 Nickel-Based

A Review on Superalloys and IN718 Nickel-Based INCONEL Superalloy Enes Akca Department of Mechanical Engineering, Faculty of Engineering and o Nimonic 90. (Ni 54% min Cr 18-21% Co 15-21% Ti 2-3% Al 1-2%) used for turbine blades, discs, forgings, ring sections and hot-working tools, A Study on the Formation of Serrated Grain Boundaries and The formation of serrated grain boundaries and its subsequent effect on creep resistance have been investigated in a wrought nickel based superalloy Nimonic 263. The grain boundaries were considerably serrated without the presence of ' phases or M23C6 when a specimen was slow-cooled from the solution treatment temperature. The high resolution observation on the lattice image of the serrated

ADDITIONAL STRENGTENING OF SUPERALLOY

Superalloy Nimonic 80A is regularly used in heat-treated condition. Heat treatment includes solution annealing at 1080 oC/8h and precipitation aging at 700 C/16h. Maximal hardness that can be achieved after that treatment is around 360HV. For certain needs automotive industry requires the hardness of this superalloy to be more than 360HV.

SUN The PortevinLe Chatelier (PLC) eect in the Nimonic 263 superalloy was investigated by tensile test in a wide temperature range, from room temperature to 1033 K (760 C), and at strain rates between 0.1 and 4 9 104 s1. Types A, B Evaluation of Die Chilling Effects during Forging of Nimonic80A is a kind of nickelbased superalloys which is used in high temperature components of land gas turbines. In this paper, the influence of four design factors:die temperature, strain rate, friction coefficient and geometry size of ring sample over the variation of internal diameters (VID) and forging load (FL) was studied. It was done by means of design methodology based on DOE

In this paper, the influence of four design factors:die temperature, strain rate, friction coefficient and geometry size of ring sample over the variation of internal diameters (VID) and forging load (FL) was studied. It was done by means of design methodology based on DOE Forging of superalloys - ResearchGateHydraulic press and open dies are used for deformation and the ingot is rotated by 45 or 90 degree at the end of each pass [2,7]. In the early stages of the ingot breakdown, the hot working Mechanical micro-drilling of nimonic 80A superalloy using Micro-drilling experiences an early tool damage which is a major drawback for nickel-based superalloy. This paper examines the wear condition on the micro-tool cutting edge, surface roughness of machined holes, and hole diameter analysis in micro-drilling of Nimonic 80A, using two types of micro-drills (uncoated and TiAlN coated) with 0.79 mm
