TL;DR: In this article, the authors investigated the effect of surface machining on the susceptibility of 304L stainless steel to stress corrosion cracking and revealed that surface machined stainless steel results in extensive grain refinement, strain induced martensite transformation and high magnitude of plastic deformation near the surface.

TL;DR: In this paper, a novel heat treatment procedure that combines the pre-strain with a two-step aging was proposed to improve both the strength and stress corrosion cracking (SCC) resistance of the high strength 7050 aluminum alloy.
Abstract: A novel heat treatment procedure that combines the pre-strain with a two-step aging was proposed to improve both the strength and stress corrosion cracking (SCC) resistance of the high strength 7050 aluminum alloy. The heat treatment included a post-quenching pre-strain of 5%, a high-temperature aging at 200 degrees C for several minutes, and a subsequent low-temperature aging at 120 degrees C for 24h. The yield strength of the samples aged at 200 degrees C for 0.5 and 1 min was higher than that of the T6 sample. The SCC resistance of these samples was improved compared to the T6 sample, due to the enlargement in the size and the inter-particle distance of the grain boundaries precipitates and the decreases in the number of the GP zone. Especially, the sample aged at 200 degrees C for 5 min exhibited a similar SCC resistance and much higher elongation compared the T76 sample. (C) 2008 Elsevier B.V. All rights reserved.
