Initiation of corrosion on reinforcing bars occurs when a critical chloride concentration is achieved. A universal value for the chloride concentration that causes depassivation has not been agreed upon for carbon steels due to a variety of experimental factors. The chloride threshold depends on the rebar material, rebar surface condition, testing environment, method of detection, definition of...

In this study, we report a procedure for producing syntactic steel foams by melt infiltration of millimeter-sized ceramic microspheres. The gravity-fed infiltration method yields steel foam with uniform distributions of microspheres and negligible unintended porosity. The critical parameters in the manufacturing process are the melt temperature and the preheat temperature of the microspheres pr...

In order to improve efficiency of cutting process in production industry, development of new steel which has good machinablity is desired. The work material which has good surface roughness, easy breakable chip and small tool wear as the good machinablity is expected. And the free-machining steel was developed owning to adding elements which could make the machinablity better. Of all others, le...

In this paper, application of ultrasonic techniques for defect detection in weldments of austenitic stainless steel and maraging steel is discussed. Applications of ultrasonic techniques for characterizing microstructural changes in AISI type 316 stainless steel and modified 9Cr-1Mo ferritic steel; thermomechanical processing of 15Cr-15Ni-2.3Mo-titanium modified austenitic stainless steel (allo...

An attempt made to optimize the operating parameters involved in an autogenous pulsed Nd: YAG laser welding process of similar and dissimilar combinations of butt joint of 2 mm thick 316 L stainless steel and mild steel. Influence of prominent laser welding parameters such as average peak power, defocus position, spot position, and shielding gas were investigated for welded joints considered. T...

The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the...

Objective The aim of this study is to identify the molecular defect of three unrelated individuals with late-onset predominant distal myopathy; to describe the spectrum of phenotype resulting from the contributing role of two variants in genes located on two different chromosomes; and to highlight the underappreciated complex forms of genetic myopathies. Patients and methods Clinical and labo...

Centrosomes, major regulatory sites for the microtubule (MT) nucleation, are regulated in a dynamic manner throughout the process of meiotic maturation. Recently, centrosome orientation in mouse oocytes has been demonstrated in metaphase I through metaphase II. However, centrosomal protein expression in concordance with MT polymerization in earlier stages of oocyte maturation from germinal vesi...
