In this study, the pitting type of corrosion growth characteristics, fatigue crack initiation and propagation behavior; axial fatigue tests were carried out on precipitation hardened martensitic Custom 450 steel in the air and 3.5wt% NaCl solution. Using the ratio of the depth to the half-width of the pits; (a/c)= 1.5±0.2 the corrosion pit depth growth law was obtained as a function of stress a...

Turning operations using single-point cutting tools have been one of the earliest and most used methods for metal. It has widely studied forces workpiece surface roughness to affect turning operations. When metal, tool needs be tougher than so it can resist high temperatures wear while operation is conducted. The mechanical qualities martensitic stainless steel (MSS) grade Custom-450 significan...

In the present study, drilling tests were carried out on Custom 450 stainless steel workpieces. The influences of control factors (cutting speed-Vc, feed rate-f and drill bit geometry-D) drilled holes’ surface roughness (Ra) size adhering workpiece (AW) to was examined. results obtained from designed based Taguchi’s L16 orthogonal array analysed using ANOVA grey relational analyses (GRA). There...

Custom 450 stainless steel and AM 350 are both precipitation hardening steels, which widely used in a variety of aerospace applications. The former exhibits very good corrosion resistance with moderate strength, whereas the latter is for applications requiring high strength along resistance. In this study, behavior CUSTOM steels passivated (a) citric acid (b) nitric solutions 50 75 min at 49 70...

The distribution of grain size parameters along 11 km stretch of the beach sediments between Karikal and Nagore, reveals that the mean grain size exhibits a marked decreasing trend on either side of the mouth of the Tirumalairajanar River which flow from west to east. The sediments are mainly of medium to coarse grained, moderately sorted, near-symmetrical skewed to fine skewed and leptokurtic ...

Longitudinal Chromatic Aberration (LCA) influences the optical quality of the eye. However, the reported LCA varies across studies, likely associated to differences in the measurement techniques. We present LCA measured in subjects using wavefront sensing, double-pass retinal images, and psychophysical methods with a custom-developed polychromatic Adaptive Optics system in a wide spectral range...
