Improvement of nondestructive inspection techniques has made more frequent the detection zones containing closely spaced non-metallic inclusions in pressure vessels low carbon steel. In present study, an in-service cylindrical horizontal vessel were detected by Scan-C ultrasonic and considered as laminations to be assessed Part 13 API 579-1/ASME FFS-1 2016 standard. The outcoming results reject...

The effect of metallic (Fe, Cu, Co, Ni, Ti) and non-metallic additives (Si, B) on the formation fullerenes from graphite powders was studied in radiofrequency (RF) thermal plasma. main component synthesized fullerene mixtures C60, but higher (C70, C82, C84) could be detected as well. Fe Cu increased content soot. In contrast, decreased presence Ti, Si, B compared to synthesis without additives....

a brief account of the representative and workable industrial minerals namely magnesite, talc and barite in lesser himalaya, is presented here emphasizing their genesis. deposits of magnesite and talc are found associated with neoproterozoic, plateform type, shelf-slope limestone-dolomite host rocks from inner lesser himalayan sequences. field, textural, geochemical signatures and fluid inclusi...

Endodontically treated teeth with excessive loss of tooth structure would require to be restored with post and core to enhance the strength and durability of the tooth and to achieve retention for the restoration. The non-metallic posts have a superior aesthetic quality. Various core build-up materials can be used to build-up cores on the posts placed in endodontically treated teeth. These mate...

Non-metallic inclusions were deformed and broken during hot cold rolling processes. The deformation of the process had an influence on property steel products. Investigations in was reviewed current study. Physical properties summarized compared, such as melting temperature, viscosity, Young’s modulus, hardness, thermal expansion coefficient, crystallization, Poisson’s ratio. deformability inde...

This study aims to evaluate the functional outcomes for fixation of transverse patella fracture (TPF) using a transosseous suturing method with non-absorbable polyester suture. A retrospective case series was conducted on 37 patients who underwent open reduction and internal technique suture at Lower Limb Department, Hospital Traumatology Orthopaedics, Ho Chi Minh City, from 1/6/2020 1/6/2022. ...

The vision of this thesis is to study how it is possible to obtain optimised workpieces during metal cutting processes in industry. Specifically, the work is aimed to increase the understanding between the steel characteristics and their link to the chip breaking and tool wear during metal cutting. The emphasis is on the influence of the cleanliness and the characteristics of non-metallic inclu...

A crystal plasticity finite-element model, which explicitly and directly represents the complex microstructures of a non-metallic agglomerate inclusion within polycrystal nickel alloy, has been developed to study the mechanistic basis of fatigue crack nucleation. The methodology is to use the crystal plasticity model in conjunction with direct measurement at the microscale using high (angular) ...
