Semisolid processing is one of the modern routes in sound and near net shape parts production.  Preparation of semisolid slurry using a cooling slope is increasingly becoming popular, primarily because of its simplicity in design and ease of control of the process. In this research, the microstructures of Al6061 semisolid alloy cast via a miniature cooling slope were investigated. The propertie...

The aim of this study is to investigate experimentally the microstructural evolution of the joints using ledeburitic AISI D2 Tool Steel parts. The application of a new process of the semisolid joining of two parts of AISI D2 cold-work tool steel is proposed using a partial remelting method. Samples were heated in an argon atmosphere up to 1300°C and held for 10 minutes. Metallographic analyses ...

The feasibility of friction stir welding to joining AC4CH semisolid cast aluminum alloy with 6061 plates was investigated, including the influence condition on mechanical properties joints. Excessive heat input conditions high tool rotational speed and low result in formation large burrs. Although hardness zone is scarcely affected by condition, as 1mm/s makes heat-affected zones both sides sof...

of ill vitro release testing as a QA tool to ensure batch-to-batch uniformity has been gaining both increasing popularity and contempt in the pharmaceutical industry. Regardless of views and opinions, it is worthwhile to be prepared to conduct such studies if necessary. Currently, the most publicized methods use horizontal ("Franz or Modified Franz") diffusion cells, with an artificial support ...

The use of two semisolid media (semisolid Rappaport and semisolid Rappaport-Vassiliadis) for the isolation of Salmonella spp. from coastal waters was compared with the use of conventional media. Two hundred and fifty six samples were studied; Salmonella spp. were detected in 83. The semisolid media were the most sensitive, detecting 73 samples instead of the 53 detected by the conventional medi...

Systematic experimental work and modeling efforts have been conducted to characterize the yield behavior of commercial aluminum alloys in the semisolid state. In this study, extensive compression experiments were performed to measure the yield stress of semisolid aluminum slurries at high solid fractions (0.5 to 1.0), and a cone penetration method was employed to measure yield stress at low sol...

application of shearing during solidification to produce a non-dendritic semisolid slurry that can be Semisolid metal (SSM) processing is a relatively transferred directly into a mould or die to give a final new technology for metal forming. Different from product. Thixoforming is used to describe the near the conventional metal forming technologies which use either solid metals (solid state ne...

Tungsten inert gas (TIG) welding, also called as gas tungsten welding 1. (a) Schematic of TIG welding Process (b) Variety of tungsten electrodes. The activated TIG (ATIG) welding process mainly focuses on increasing the depth of penetration and the reduction in the width of weld bead has not been paid. Tungsten inert gas welding, TIG is widely applied in manufacturing process for different The ...

Gas tungsten arc welding (GTAW) or Tungsten inert gas welding (TIG) is one of the widely used techniques for joining ferrous and non-ferrous metal.Gas tungsten arc welding process,consist of non-consumable tungsten electrode which is used to provide the arc for welding. During the welding cycle a shield of inert gas expels the air from the welding area and prevents oxidation of the electrode, w...
