The Generation, Measurement, Prediction, and Prevention of Residual Stress in Nickel-Based Superalloys: A Review

Machines
As a crucial high-performance material, nickel-based superalloys inevitably generate residual stresses during processing, manufacturing, and usage. The mechanical properties of nickel-based superalloys are significantly reduced by residual stress, which ...

TLP Weldability of Nickel-Base Superalloys

Journal of the Japan Welding Society, 1980
The TLP (Transient Liquid Phase) weldability of nickel-base heat-resistant alloys (Hastelloy X, Inconel X-750 and Udimet 500) have been studied by microscopy, electron-probe-microanalysis, tensile tests and stress-rupture tests of the joints.The major cause to restrict the TLP weldability was the formation during welding of a continuous array of stable

Addition of silicon improves oxidation resistance of nickel based superalloys [PDF]

, 1974
Specific weight changes of nickel-base superalloy B-1900 and B-1900 + 1% Si specimens were tested at 1273 K. B-1900 was losing weight at an increasing rate due to spalling of oxide scale while B-1900 + 1% Si was still gaining weight at low, nearly ...
