THE REACTION between liquid zinc and steel, such as occurs during hot-dip galvanizing, shows some unusual kinetic features which as yet have not found a completely satisfactory explanation. The upon recent results from the in our laboratory. The main kinetic features (a) For silicon-free steels the purpose of this note is to present a mechanism based literature and some preliminary experiments ...

With careful design, mixed microstructures consisting of fine plates of upper bainitic ferrite separated by thin films of stable retained austenite have exhibited impressive combinations of strength and toughness in highsilicon bainitic steels. The silicon suppresses the precipitation of brittle cementite leading to an improvement in toughness. The essential principles governing the optimisatio...

There is now a large volume of sophisticated steels which rely on silicon as an alloying addition with the purpose of avoiding the precipitation of cementite. But there is also evidence that the silicon can enhance the formation of ε–carbide; the mechanism of this effect is not understood and the absence of appropriate thermodynamic data makes it impossible to conduct calculations. We report he...

A number of investigations carried out in an abrasive jet machining process having a traditional material with traditional nozzle. In some publication are focusing on water jet cutting machining and some are focusing on sand bond grinding , some work are wear behavior of nozzle and some are on performance of material in water jet machining. The present research work give an analysis of performa...

This paper studies the homogenization of quasi-static and nonlinear Maxwell’s equations in grain-oriented (GO) silicon steel laminations. GO silicon steel laminations have multiple scales and the ratio of the largest scale to the smallest scale can be up to 106. Direct solution of three-dimensional nonlinear Maxwell’s equations is very challenging and unrealistic for large electromagnetic devic...

In this study, two silicon-containing steels with different P contents were used, and reheating tests were conducted in an industrial furnace in a hot strip plant. The effect of P on the microstructure and melting temperature of Fe2SiO4 in silicon-containing steels was investigated using a backscattered electron (BSE) detector and energy-dispersive spectroscopy (EDS). The melting process of Fe2...

A facile solution-based technique was developed to grow vertically aligned TiO2 nanowires with predominantly anatase phase on arbitrary substrates of stainless steel, glass, silicon wafer and carbon cloth at the low temperature of 80 °C and in an open atmosphere.

High-silicon steels have long been known to possess exceptional resistance to tempering, but the reasons for this effect were unknown. We report here a study of the third stage of tempering of these steels, in which cementite is formed. In a 0.75 wt% C 1.4 wt% Si alloy steel, tempered for 1 hour at 380°C, it is found that silicon atoms are rejected from the growing cementite into the ferrite ma...

Silicon rods are widely employed for frontalis sling suspension. However, on passing through the tissues, at times, the silicon rod gets detached from the stainless steel needle. This occurs more commonly in patients of blepharophimosis syndrome, in which hypoplasia of superior orbital rim with deficiency of skin between lid and brow, causes difficulty in passage of the needle when it is manipu...
