Steel under strain hardening and recrystallization
Abstract: Cold working is deformation process to obtain zero tolerance over finished parts. Requisite quantity of measurement inexpensive neither the fact by undesirable hardness increase and requirement of intervened processing, which may include machining tolerances. Moreover recrystallization another arena to circumscribe to get fine grained studies to include expenses of hardness tolerances. Nevertheless many naming tolerate many steps interleaved among steps under standard. These prevailed to write such access of simple …

Study the effect of lubrication on hardness in the ring compression test
Abstract: Mild Steel is commonly used to produce automotive parts such as shafts, gears and bearings. This paper focuses on the hardness distribution in the mild steel ring specimen after compress under rigid dies. Three different types of lubricants namely boric acid, Vaseline, grease and dry condition were employed as lubricants and the coefficient of friction corresponding to the lubricant evaluated using standard ‘Ring compression test’. The strain distributions obtained from …

Electrochemical Etching on Copper Surfaces to Achieve Superhydrophobicity
Abstract: In the present study, an attempt has been made to create superhydrophobicity on copper substrate by etching the surface at different parameters (current density and time). Etching time was varied from 30 to 240 minutes. Untreated copper surface exhibited contact angle of 91.4°. The best etched surface exhibited a maximum contact angle of 142.1° for a current density of 0.01A/cm2 and etching time of 60 minutes. The structure–property relationship of …

Fault Diagnosis of Helical Gear Box Using Variational Mode Decomposition with Naïve Bayes and Bayes Net Classifiers through Vibration Signals
Abstract: Gear is a very important machine component which finds use in most of the machines which requires some sort of power transmission or reduction. Unattended faults in gears can be catastrophic for the machine leading to halts in production and consequent economic loss. The requirement for a gear fault detection and diagnosis system is thus emphasized. Vibration signals are often used in fault diagnosis applications along with Fast Fourier transform …
