"Fracture Behaviour of Nickel-Titanium Laser Welded Joints
Published: August 01, 2009
Authors: C. Maletta, A. Falvo, and F. Furgiuele, University of Calabria; G. Barbieri, CR ENEA Casaccia; M. Brandizzi, Consorzio CALEF
In this study, the effects of Nd:YAG laser welding on the fracture behavior of Ni-rich nickel-titanium sheets are analyzed by experimental investigations. The welding was carried out in open air conditions by using a special shielding/clamping system to avoid the chemical contamination of the molten zone and the formation of hot cracks.
"RECAST" The Repair of Airfoils When Welding is Unacceptable
Published: 2003
Authors: J. Burke Flight Support Inc, North Haven, Connecticut, USA
The age-old problem of fixing a flaw in an airfoil of a vane or bucket that is otherwise serviceable, has been resolved by the careful blending of two known technologies, HVOF (High Velocity Oxy Fuel) and HIP (Hot Isostatic Pressing).
"The Unbearable Lightness of the Cube": Using SMA to Express Lightness, Movement and Memory in Sculptures
Published: December 01, 2008
Authors: Rolf Gotthardt, Ecole Polytechnique Federale de Lausanne; Etienne Krähenbül, Romainm tier
Shape Memory Alloys (SMA) have been used in sculptures for quite some time. But only very few of these sculptures have gone on to earn wide recognition, mainly because the working conditions of the SMA must be carefully respected when sculptures are made. If they are not, the sculpture is bound to fail after a short time.

eut +Cu soldering materials, part I: Wettability studies
Published: April 01, 2004
The maximum bubble pressure, dilatometric, and meniscographic methods were used in investigations of the surface tension, density, wetting time, wetting force, contact angles, and interfacial tension of liquid (Sn-Ag)eut and two (Sn-Ag)eut+Cu alloys (Cu at.%=0.46 and 0.74).

eut +Cu soldering materials, part II: Electrical and mechanical studies
Published: April 01, 2004
Electrical (solder resistivity and solder joint resistance) and mechanical (tensile strength and shear strength of solder joints) parameters of the binary eutectic Sn-Ag and two alloys close to the ternary eutectic Sn-Ag-Cu composition were investigated. The four-probe technique was used for the measurement of electrical parameters.
