... associated with the sparking phenomena. Welsh later studied the increased wear resistance of spark‐hardened materials, including non‐ferrous alloys of titanium and aluminium (Welsh, 1957, 1958 ; Welsh and Watts, 1962). Welsh determined that by selecting an appropriate electrode material to produce the spark...

...E. Asua; V. Etxebarria; A. Garcia; J. Feuchtwange Purpose The purpose of this paper is to focus on the use of a nickel‐titanium (nitinol) shape memory alloy (SMA) wire (capable of showing strains of up to 8 per cent) as the active element that drives a flexible and lightweight micropositioning...

... with a brief review of recent research and future prospects. Findings SMMs include shape‐memory alloys (SMAs), ferromagnetic SMAs (FSMAs) and shape‐memory polymers (SMPs), which change shape when influenced by temperature and other stimuli. SMAs comprising nickel‐titanium alloys were discovered...

...Robert W. Messler, Jr; Scot Bohnenstiehl; John Levene; Erika Johnson; Luo Chen Being inherently a non‐pressure fusion process, laser‐beam welding (LBW) has been shown to have difficulty compared to resistance spot welding for weld‐bonding Al alloy structures, despite the many structural...
