How to improve the bonding ability and quality performance of heterogeneous plates has always been one difficult problems in field high-performance composite sheet forming manufacturing. In this paper, a new manufacturing method clad plate, hard plate rolling is proposed. The hot process Al/Mg/Al slab with or without was studied. results show that shear stress direction (RD) can be transformed ...

the present study is a designed protocol for investigation of the analgesic effect of oral and intraperitoneal (i.p.) administration of alcoholic datura stramonium (ds) seed extract as a rich source of alkaloid substances. male nmri rats were divided into control and treatment groups. the treatment rats received different doses of the ds seed extract, which was prepared from alcoholic smashed s...

Abstract The paper discusses the topic of butt welding polyurethane drive belts by hot plate method in context modeling process this technological operation. Based on analysis process, a series studies thermomechanical properties material from which belt is made has been planned. results will be used for mathematical and particular its most important phase: plasticizing On basis, study compress...

There are mainly two kinds of laser used in welding materials, continuous beam (CLBW) and pulsed (PLBW). The have each characteristics. Compared with CLBW, the heat input PLBW can be controlled lower, has been widely connection thin plate materials. Since pulse shaping edited to realize preheating slow cooling process, studied suppress hot cracks other defects field aluminum alloy, magnesium al...

Ultrasonic complex vibration welding of same and different metal specimens and structures of the welded area are studied using several complex vibration welding systems, scanning and transmission electron microscopes (SEM and TEM). Ultrasonic welding can weld various metal directly using vibration and static clamping pressure. The welding area is limited very narrow layer and can weld different...

In most industrialized countries large numbers of workers are exposed to welding fumes. Although the general pattern of welders' health may not significantly differ from that of workers in other dusty industrial occupations which demonstrate elevated incidence of respiratory tract diseases with long latency periods, the extremely wide range of substances at potentially high concentrations produ...

It is not known for certain that dental stone components influence titanium welding. In this study, we investigated metallurgical problems caused by laser welding on dental stones using wrought commercial pure (CP) titanium. A pulsed Nd:YAG laser irradiated a number of specimens' surfaces which were fixed on either a dental hard stone or a titanium plate. The metallurgical properties of the wel...

The residual strain profiles were measured through the thickness of friction-stir welded (FSW) plates using neutron diffraction to study the relationship between the angular distortion and the residual strain distribution. Three different weld specimens were prepared from a 6061-T6 aluminum alloy with the purpose of separating the effects of the frictional heat and plastic deformation on the re...
