Microstructures and mechanical properties of ultrafine grained 7075 Al alloy processed by ECAP and their evolutions during annealing
Microstructures and mechanical properties of equal-channel angular pressing (ECAP) processed and naturally aged ultrafine grained (UFG) and coarse grained (CG) 7075 Al alloys as well as their evolutions during annealing were investigated. After the same natural aging, the tensile yield strength, ultimate strength, and microhardness of the UFG samples were 103%, 35%, and 48% higher, respectively...

متن کاملCorrosion resistance of Si-Al-bearing ultrafine-grained weathering steel.
In the Ultra-steel project at the National Institute for Materials Science (NIMS), which run from 1996 to 2005, high-Si-Al-content ultrafine-grained (UFG) weathering steel was developed by grain refinement and weathering guidance. It was found that this steel has excellent strength, toughness and corrosion resistance. Samples were prepared by multi pass warm rolling at temperatures between 773 ...
متن کاملMicroalloying Ultrafine Grained Al Alloys with Enhanced Ductility
Bulk ultrafine grained (UFG)/nanocrystal metals possess exceptional strength but normally poor ductility and thermal stability, which hinder their practical applications especially in high-temperature environments. Through microalloying strategy that enables the control of grains and precipitations in nanostructured regime, here we design and successfully produce a highly microstructure-stable ...
متن کاملTexture dependent strain rate sensitivity of ultrafine-grained aluminum films
Article history: Received 25 October 2015 Received in revised form 2 December 2015 Accepted 3 December 2015 Available online 17 December 2015 We investigated the strain rate sensitivity (SRS) of freestanding ultrafine-grained aluminum films with similar thickness (~240 nm) and mean grain size (~275 nm) but highly dissimilar texture. For (110) textured bicrystalline films, flow stress increased ...
