“…Multiple samples were produced with VHP temperatures of 475 °C, 490 °C, 525 °C and 600 °C. Samples were then processed in order to improve the properties of the Al matrix with a solutionizing heat treatment at 490 °C and peak ageing at 121 °C for 24 h. Single edge notch (SEN) specimens were then cut from the panel, resulting in a line of Ni–Ti particles down the centreline as shown in Figs.…”

A multi‐functional aluminium alloy 7050 (AA7050) containing embedded Ni–Ti shape memory alloy particles to detect fatigue crack growth is proposed. The regions of intense strain near the tip of a growing fatigue crack cause nearby Ni–Ti particles to undergo a solid‐state phase transformation from austenite to martensite, releasing a detectable acoustic emission signal that can be used to locate the crack in the monitored component. The AA7050/Ni–Ti composite was made by vacuum hot pressing Ni–Ti powder between rolled AA7050 plates. The effect of hot pressing temperature and subsequent heat treatments (solutionizing and peak ageing) on the Ni–Ti particles was studied. A successful proof‐of‐concept was demonstrated for AA7050 with embedded particles that emit a measureable and repeatable acoustic emission signal in the presence of a fatigue crack, allowing for quick diagnosis of fatigue crack damage in this material.

“…The texture evolution of aluminum alloys during rolling and subsequent annealing has long been a subject of research as the anisotropy of mechanical properties is significantly influenced by the texture developed during processing [1][2][3][4][5]. During rolling initial orientations are gradually rotated into the stable end orientations located on the ␤ fiber, which runs from the brass (B) orientation {1 1 0} 1 1 2 through the S orientation {1 2 3} 6 3 4 to the copper (C) orientation {1 1 2} 1 1 1 [1,2].…”
