Highly coercive Sm-Co-based permanent magnets have been achieved through simple modification of binary Sm12Co88 alloys with Nb, C or combined Nb and C at concentrations ranging from 1 to 10 atomic percent processed via rapid solidification. Melt spinning at 40 m/s resulted in the formation of the metastable TbCu7-type structure in all alloys. While the unalloyed, as-solidified Sm12Co88 alloy di...

Submit Manuscript | http://medcraveonline.com process important aspect of study [2-5]. The cleanliness of steel is a most required process of industry [6]. Various methods have been used to enhance the properties of steel during solidification. The continuous casting mold and submerged entry nozzles play an important part to produce the clean and defect free solidified slabs [7]. The melt flow ...

A conceptual design was developed for a cosmo-biology experiment. It is intended to expose simulated interstellar ice materials deposited on dust grains to the space environment. The experimental system consists of a cryogenic system to keep solidified gas sample, and an optical device to select and amplify the ultraviolet part of the solar light for irradiation. By this approach, the long last...

A simple and rapid solidified vortex assisted 1-undecanol based liquid-liquid microextraction technique was proposed for preconcentration of trace levels of lead ions. The extraction solvent (1-undecanol) was dispersed into the aqueous samples by the assistance of vortex agitator. 100 µL of 1-undecanol containing ethyl (2Z)-3-[(5-chloro-7-methyl[1,3]thiazolo[5,4-d]pyrimidi...

In the present study, the effect of time and base metal microstructure on the Transient Liquid Phase (TLP) bonding of 304L stainless steel was studied. TLP was performed at 1050 0C for 5 and 60 minutes on the coarse grain austenitic and martensitic microstructure using BNi-2 interlayer. To prepare martensitic microstructure, as-received 304L was rolled at -15 0C up to 80% rolling reduction. TEM...

Microstructural and mechanical characterization of 10 vol% SiC particles (SiCp) reinforced 6061 Al-based composite fabricated by powder thixoforming (PTF) was investigated in comparison with the PTF and permanent mold cast (PMC) 6061 monolithic alloys. The results reveal that the microstructure of the PMC alloy consists of coarse and equiaxed α dendrites and interdendritic net-like eutectic pha...

The objective of this paper is to demonstrate the ability of simulating thermal-solute double diffusivities problem, which is usually calculated via mini-supercomputer or supercomputer, by using typical personal computer (PC). The “plume” phenomena due to buoyant force of lighter liquid solute during solidification will be illustrated. The conduction, convection and macrosegregation predicted b...
