Steel possesses mechanical properties that can enhance the hardness and microstructure of its surface, and heat treatment is one way to achieve these properties. This study aimed to investigate the impact of different cooling media on the heat treatment p... see more

Abstract - The effect of age hardening heat treatment on the hardness values of 93.95Al-5Zn-1.05Sn/5Al2O3-SiO2 particulate composite has been studied. The data used for the work was generated at the National Metallurgical Development Centre, Jos Foundry s... see more

This research was aimed to examine the heating effect at 70? C for 3.5 seconds on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) decontamination in edible bird´s nest. This study used 40 clean edible bird´s nest samples. Samples were div... see more

Stress concentrations cause many machine element failures. Failure will occur more rapidly if the machine elements obtain repeated and fluctuating loading. For this reason, the material for machine elements must have better fatigue life. There are various... see more

Duck eggshell contains very high calcium, making it a raw material for hydroxyapatite (HA) biomedical applications. The aim of this study was to synthesize natural HA from duck eggshell waste using cleaning, drying, smoothing with a smoothness level of pa... see more

This paper investigates the heat treatment of flint practiced at the Neolithic site of Hasankeyf Höyük in southeast Turkey. It does not involve petrographic or geochemical analysis to identify the physical and chemical evidence of heat treatment but aims ... see more

Hydrogen storage merupakan salah satu kunci dalam pengembangan sumber energi hidrogen (H2) komersil. Magnesium diketahui memiliki kapasitas penyimpanan hidrogen yang relative cukup tinggi 7,6%. Dalam penelitian ini, dilakukan sintesa Mg2-xAlxNi dari serbu... see more

Aluminum and its alloys are metals that are widely used in the engineering field because its have advantages including good formability, relatively high tensile strength, corrosion resistance and a welding process for the joints. General structure, struct... see more
