This book was released on 2014 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation characterises the fracture toughness of the very high strength Aluminium alloy 7449. This Al-Zn-Mg-Cu alloy is heat treatable and relies on rapid quenching from the solution heat treatment temperature to promote subsequent artificial aging. While the influence of quench paths on strength is well understood and can be predicted using techniques like quench factor analysis, the influence of quench rate on fracture toughness is more challenging. The rate of quenching can influence the fracture toughness through complex precipitation reactions occurring during cooling. The precipitate locations dictate the magnitude of the detrimental effect on the fracture toughness. In this investigation, the fracture toughness of 7449 in two product forms was measured using compact tension specimens cut from forged blocks and rolled plate. These plane strain (KIC) results were also augmented with Charpy impact tests. Various quench conditions were investigated, including water at three different temperatures and poly oxyethylene glycol (PAG) in two concentrations. The influence of standard and novel aging procedures including retrogression and reaging was also determined. The combinations of strength and toughness have been related to the prevailing microstructural condition. Fracture toughness magnitudes were found to vary most significantly with rapidity of cooling from the solution treatment temperature, with the subsequent aging treatments having a much smaller effect.

Download or read book Carburizing written by Geoffrey Parrish and published by ASM International. This book was released on 1999-01-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Based on his training in metallurgy and experience in a large British gear manufacturing company, Parrish reviews the microstructural features of metal products that have been carbon case-hardened, and the influence of those features on the more important material properties. He is not concerned with the carbonizing process at all. He primarily addresses students of engineering and ferrous metallurgy, but also stress and design engineers who might want to understand more fully the specifications of the materials they are considering for their designs. He wrote the eight articles to summarize the field's literature of the early 1970s for his own convenience, but at invitation, published them as a series in the Heat Treatment of Metals during 1967-77, and collected them for a first edition of the volume in 1980.

Download or read book Chapter Formability and Performance of Al Zn Mg Cu Alloys with Different Initial Tempers in Creep Aging Process written by Heng Li and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The initial temper may directly affect the deformation behavior and material performance in creep age forming (CAF) process. Five heat treatment states are selected as the initial tempers for CAF, namely, solution, peak-aging (T6), over-aging (T73), retrogression and re-solution. The formability and performance of an Al-Zn-Mg-Cu alloy with the above initial tempers in creep aging process are investigated via using creep and stress relaxation aging tests, mechanical property tests, corrosion resistance tests and microstructure analysis. The differences of formability are attributed to the inhibitions of different distributed matrix precipitates (MPts) on the dislocation movement, namely, the more coarsening the MPts is, the easier the dislocation movement. During creep aging process, the mechanical properties are improved for the solution, retrogression and re-solution tempers with fine MPts, but reduced for the T6 and T73 tempers due to coarsening of MPts. Since the distribution of grain boundary precipitates (GBPs) becomes discontinuous, the corrosion resistances of the creep aged specimens are enhanced for all initial tempers. Taking both mechanical properties and corrosion resistances into account, the re-solution temper may be a preferable choice to achieve high performance of the components beyond the precise shape in CAF.
