Abstract: The description of the Retraction: Owing to the authors' ignorance, a SEM picture (fig.3(d) in this paper) has been used in another paper (Fig.3(b) in a Chinese Journal). After carefully thinking, the authors decided to withdraw the paper with pity. This decision has been approved by both Editorial Office of JMMR and all authors. We apologize for the inconvenience may caused to readers. Date of Retraction: July 10, 2023 The announcement of this... More

Abstract: Flocculation presents one of the most effective methods for enhancing separation of both anthropogenic and natural suspensions by sedimentation, filtration and flotation techniques.The flocculation effectiveness much depends on the medium shear rate in a flocculator. The objective of this research comprises the study how the suspension dispersity and concentration effect the efficiency of its flocculation in a static tubular flocculator and in a... More

Abstract: Metal swarf is unavoidable material in metal processing industry, also metal swarf treatment lead to cost savings by metal waste reduction and removing the cutting fluid waste, that cause to increasing process stability and metal value. It is interested that in how to recycle metal swarf especially when swarf surrounded by cutting fluid, is considered because these waste are classified as hazardous waste. The aim of the study is to increase the... More

Abstract: This article is described the various possible schemes of severe plastic deformation, by ECAP process that allows receiving metal with ultrafine-grained structure. The results of computer simulation and TEM investigations of aluminium alloy 6060 were presented. It is shown that the equal-channel angular pressing in the proposed matrix with a quasi-starched channel joint angle 45° provides the formation of a homogeneous subgrain structure with a... More

Abstract: Thermal barrier coating (TBC) system composing of bond coat, having two different metallic bond coating materials such as NiCoCrAlY and CoNiCrAlY, and top coat, 8YSZ (8 wt%Y2O3-ZrO2) ceramic coating was deposited on aluminum-based alloy by atmoshpheric plasma spray (APS). Fatigue test and tensile test both was performed for TBC sample. The tensile test and fatigue, both results showed that that fracture occurred in 8YSZ coating near the... More
