During experimental studies of the equal-channel angular pressing-drawing effect on microstructure evolution and mechanical properties change, principal possibility effectiveness using proposed continuous method for forming an ultrafine-grained structure increasing strength steel-aluminum wire was proved. The deformation carried out at ambient temperature in three passes. It is shown that both ...

Abstract The single point incremental forming (SPIF) process is a flexible and progressive manufacturing technique in the monolithic molding domain of heterogeneous metal pressing panels, which can contribute to panels with complex contour applicable fabrication small amount titanium mesh plates for cranial prosthesis. A sandwich construction was proposed this paper purpose inhibiting indentati...

The present study aimed to evaluate the influence of various heat-pressing procedures (different holding time and heat pressing temperature) on the microstructure and flexural strength of lithium disilicate glass ceramic. An experimental lithium silicate glass ceramic (ELDC) was prepared from the SiO2-Li2O-K2O-Al2O3-ZrO2-P2O5 system and heat-pressed following different procedures by varying tem...

Rats undergoing extinction of lever pressing after an external feedback for this behavior was attenuated by extinguishing its Pavlovian association with the reward (signal attenuation) exhibit compulsive lever pressing. The present study tested the effects of temporary inactivation of the orbital cortex in rats undergoing extinction of lever pressing that was or was not preceded by signal atten...
