01 Jun 1973TL;DR: In this paper, severely shot peening of the alloy surface is used to break up the structure of the original grains at the surface and grain boundaries are no longer continuous, this peening treatment is preferred for the treatment of susceptible austenitic chromium-nickel-iron alloys.
Abstract: Intergranular corrosion is prevented in sensitization susceptible alloys by severely shot peening the alloy surface so that the structure of the original grains at the surface is broken up and grain boundaries are no longer continuous, this peening treatment being done prior to exposure of the alloy to the sensitizing temperature. The method is preferred for the treatment of susceptible austenitic chromium-nickel-iron alloys, particularly the austenitic stainless steels of the 18-8 type.

TL;DR: In this article, after the carbide tips have been silver soldered to a temperature above the temperature at which the plate hardness is reduced to a hardness at which glass bead peening can achieve penetration of the surface metal and then simultaneously glass beads peening the edge and opposite sides of the saw in the peripheral region thereof.
Abstract: Stress concentration and cracking failures in the tooth and gullet regions of carbide-tipped saws are eliminated by heating the saw after the carbide tips have been silver soldered thereto to a temperature above the temperature at which the plate hardness is reduced to a hardness at which glass bead peening can achieve penetration of the surface metal and then simultaneously glass bead peening the edge and opposite sides of the saw in the peripheral region thereof.

TL;DR: A description of various mechanical operations employed in the remanufacture of gas turbine engine compressor components such as blading, rotor disks and spacer, vane shroud assemblies and air seals are given in this article.
Abstract: A description of the various mechanical operations employed in the remanufacture of gas turbine engine compressor components such as blading, rotor disks and spacer, vane shroud assemblies and air seals are given. The operations described include tungsten inert gas, plasma needle arc and electron beam welding, furnace and torch brazing, glass bead and shot peening, magnetic particle and ultrasonic inspection, plasma spray and diffusion coating. Emphasis is given to the effect of these operations on the mechanical integrity of the engine component. For example, the effect of welding, brazing, peening and diffusion coating on the high cycle fatigue strength of compressor stator and rotor components is discussed. The effect of repair operations on jet engine compressor performance is also considered.Copyright © 1973 by ASME
