This research has studied the effects of copper contents in Sn-based solder (i.e. Sn-0.7Cu, Sn-1.0Cu, and Sn-3.0Cu) on intermetallic phase formation growth during soldering. In experiments, reflow soldering was performed at 350 °C with Cu substrate by using three solders for various times 10, 20, 40, 60, 120, 240 480 s. XRD data have shown that η-Cu6Sn5 ε-Cu3Sn phases hexagonal crystal structure were present between substrate. The presence found only when soldered least content had...
This study presents a novel approach in enhancing the flexural strength of sisal fiber cement composites by employing dual coating technique with natural rubber latex and expanded perlite to fibers. The effects different content (0.25, 0.5, 0.75, 1, 1.25, 1.5 wt%) length (1, 2, 3 cm) on physical mechanical properties were also studied. properties, including bulk density water absorption, evaluated via Archimedes method. Flexural was measured using 3-point bending method, microstructure...
The aim of this research was to investigate the effect silicon (Si) on microstructure and corrosion behavior CoCrMo alloys. concentration Si added in alloys 0.1, 0.5 1 wt %. present investigated using potentiodynamic polarization measurements. normal saline solution with 0.9 % used as an electrolyte. Polarization curves obtained from test were evaluate terms current density (icorr), potential (Ecorr) parameters that be compute resistant property a sample during compared X-ray diffraction...
Abstract Metallic phase change materials (MPCMs) are attracting considerable attention for their application in thermal energy storage. Al–Si alloys considered potential MPCMs; however, to develop storage systems/modules, it is crucial fabricate corrosion-resistant MPCMs. In this study, the corrosion behavior of Co−28Cr−6Mo−1.5Si (wt%) alloy was examined via immersion tests commercial Al−Si (ADC12) melt at 700°C 10 h. The results were compared those obtained pure Al. Substrate thickness loss...
Abstract This research investigates the effects of different Si concentrations on microstructure and mechanical properties Co–Cr–Mo–xSi alloys. The concentration (x) was 0.1, 0.5, 1.0, 3.0 5.0 wt%. experimental heat-treated alloys determined by hardness tensile tests. analyzed using SEM. analysis revealed that played a role in formation intermetallic phase presence significantly decreased ductility However, improved increased directly proportional to fraction precipitating
Mouthwashes are used during dental treatments to mitigate the complications caused by poor oral hygiene. However, these solutions also affect properties of appliances, including those in orthodontics. This point has been investigated this study focusing on changes mechanical polymeric orthodontic ligature ties. Commercial ties from four brands were characterized terms their maximum forces and displacement, delivery forces, molecular structures, microscopic morphology. These compared against...

The effects replacement contents compressive molding force on bulk density, water absorption, flexural strength were observed. In mixture mortar, content sand was replaced with ranging from 0 to 15% by weight. specimen pressed under uniaxial varied 20 40 kN then de-molded cured in humidity for 28 days. With increase 15 wt%, density decreased 2118...
Hydrogen sulfi de (H2S) is one of the most common pollutants found in natural gas and industrial waste. Over few decades, removal H2S has become a signifi cant problem.

Dental caries are one of the major oral health problems, which could be mitigated by addressing dental defects. Hydroxyapatite (HA) is commonly used for tooth and bone replacement due toits similar properties as native hard tissues. Natural sources with abundant availability, such eggshells, to synthesize HA. Moreover, presence fluorine in HA, it was suggested that performance this material enhanced terms stability anti-caries properties. This preliminary study aims compare two methods...
Microwave hybrid heating (MHH) is a novel method to enhance ceramic sintering at high temperatures. The mechanism by MHH involves two directions of heat transfer for materials: microwaves the sample from inside out, while susceptor provides conventional outside. This unique offers several advantages, including uniform heating, rapid sintering, and enhanced microstructure properties materials. study investigates configuration silicon carbide (SiC) susceptors microwave heating. oven...
