this study is focused on investigating the parameters of laser percussion drilling process of nickel-base super alloy inconel 718 with thickness of 1 mm. fiber laser with the power of 500 watts was used as the laser source. laser pulse frequency, duty cycle, laser power, focal point position, were assumed as the laser drilling process variables. the hole geometry features, i.e. entrance hole di...

MICROSTRUCTURAL STUDIES ON LASER WELDING OF INCONEL 718 TO 2304 DUPLEX STAINLESS STEEL WITH A FOCUS OPTIMAZING PROCESS PARAMETERS AND ACHIEVING THE MAXIMUM FRACTURE STRENGTH

In this study, the effect of a high-speed AP 7.62 bullet on Ti6Al4V, AISI 4340, Inconel-718, AlSi10Mg and Al 6061 - T6 materials at different impact angles were investigated by using finite element package software LS-DYNA 971. 4340 was taken as material 850 m/s speed for ballistic investigation. Angle obliquity against plates has been in range 0-80º. Simulations carried out 5 degrees increment...

The direct laser deposition (DLD) process has seen rigorous research in the past two decades due to its ability directly manufacture products followed by minimal machining. input variables play a vital role determining properties achieved manufactured DLD method. Inconel 625, nickel-based superalloy with exceptional mechanical performance and corrosion resistance, been used critical application...
