Laser welding is used in critical component production when tight tolerances like minimal
distortions and residual stresses are required. Laser beam welding offers a lower heat input …

For the latest high density compact devices, thermal management is crucial for their effective
heat dissipation and system reliability. In literature, microchannel heat sink has been …

Mechanical losses consume about 40% of the total energy developed by a typical
automotive engine. The piston–cylinder system accounts for 50% of the engine frictional …

An attempt is made to reduce the residual stresses by means of vibratory stress relief (VSR)
by using an electromagnetic exciter. This paper examines the residual stresses induced in a …

Incoloy alloy 800 is a superalloy particularly suited to aggressive corrosive environments.
Both weld quality and productivity may be enhanced when joining parts by laser beam …

In the frame of the circular economy, welding of Ni-based superalloys has gained increasing
importance when applied, for instance, to repairing highly expensive components widely …

We study the microstructure and mechanical properties of friction stir processed AZ91D cast
magnesium alloy under various conditions of heat treatment. It is shown that, in the initial as …

The operating effectiveness of Indian boilers is significantly compromised by the severe risk
constituted by the early breakdown malfunctioning of boiler tubes, particularly in those …

The present study aims to compare the hot corrosion resistance of bare and Ni-20% Cr
coated Ni-Fe based superalloy 825 in Na 2 SO 4-60% V 2 O 5 molten salt environment at …

The present experimental study investigates the characteristics of a 1.2 mm thin sheet of
Nimonic 80A superalloy. This material has been selected for CO2 laser welding (LBW) view …
