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...

Now a days a manufacturing system is oriented towards higher production rate, quality, and reduced cost. Surface roughness is an index for determining the quality of machined products and is influenced by the cutting parameters. In die manufacturing industries Surface roughness of dies are considered as a vital quality characteristic. For the complex shapes of a die, three dimensional machining...

This research focuses on studying the mechanical, tribological, and corrosion behaviors of alloy steels: AISI 4340, 5140, 8620 by laser hardening, respectively. In light tests which have been carried out meticulously, it is concluded that optimum hardening parameter for all steel grades 4 mm/s scanning speed 1300?C surface temperature. Micro-structural changes, Vickers hardness as mechanical pr...
