In this study, the main task is to identify best cutting parameters improve machining performance during MQL-turning with various fluids like coconut oil, ground nut sunflower soyabean and blassocut oil. Cutting temperature surface roughness were used as metrics, goal of minimizing these responses. To construct an experimental plan for turning AISI4130 uncoated brazed carbide, full factorial de...

In this study, the effect of quenching and partitioning (Q&P) heat treatment on structural mechanical properties AISI 4130 steel was investigated. The Q&P process followed at a quench temperature 270 oC three different temperatures 270, 330, 380 oC. phase characterization prepared spicimens were done using X-ray diffractometer (XRD) scanning electron microscopy (SEM), respectively. samples also...

We have made a multiwavelength study of the overlapping error boxes of the unidentified γ-ray sources TeV J2032+4130 and 3EG J2033+4118 in the direction of the Cygnus OB2 association (d = 1.7 kpc) in order to search for a pointsource counterpart of the first unidentified TeV source. Optical identifications and spectroscopic classifications for the brighter X-ray sources in ROSAT PSPC and Chandr...
