An effect of tempforming on the microstructure, carbide precipitation, and strengthening mechanisms high-strength low-alloyed steel has been analyzed. The quenched was subjected to 1 h tempering at a temperature 873 K, 923 or 973 K followed by plate rolling same temperature. Tempforming resulted in formation an ultrafine grained lamellar-type microstructure with finely dispersed carbides (Nb,V)...
The present study aimed to evaluate the bioactivity of titanium surfaces sandblasted with large-grit corundum and acid etched (SLA) plus further alkali or hydrogen peroxide and heat treatment for dental implant application. Pure titanium disks were mechanically polished as control surface (Ti-control) and then sandblasted with large-grit corundum and acid etched (SLA). Further chemical modifica...
The various welding parameters such as welding speed, voltage and gas flow rate were varied on HSLA steel and the effects of these parameters on weld bead geometry such as penetration, width & height have been studied. Mathematical equations have been developed using factorial technique. And the result of various effects are shown in tables. (Numerical Values). INTRODUCTION Wide variety of stee...
