Abstract

The main problem which is the focus point of this study is focused on the criticism of sanad, the purpose of which is to find out the truth of hadith from the point of view of authenticity and originality. Then the hadith scholars have attempted to classify and distinguish the hadiths that really come from the Prophet from human words that speak on behalf of the Prophet under the guise of false hadiths. Therefore, the presence of various terms or methods such as takhrij al-hadith greatly facilitates hadith reviewers in determining the status of hadith whether the hadith really originates from the Prophet or not. With this, it can be seen that the perfection of a hadith is if it fulfills the conditions, namely the sanad is continuous, narrated by a just person, narrated by a dhabit person, does not contain syadz or illat. The research method used is (library research) focused on books, books, journals, and applications such as Maktabah Syamilah, Hadis Shoft, Lidwa Pustaka, Tahzīb al-Kamāl fi al-Asmā' Rijāl, Tahzīb at-Tahzīb, Al-Mu'jam al-Mufahras li Alfādzi al-Hadīs al-Nabawī, and Mausu'ah al-Atrāf al-Hadīs al-Nabawī al-Syarīf. And the steps taken are using two takhrij methods 1) Takhrij by using the first pronunciation of the hadith matan, 2) Takhrij by using one of the pronunciations of the hadith matan.

Abstract

Abstract: This research systematically concentrates on the effect of different dyeing temperatures on the mechanical properties of AISI 1045 steel which has an important role in the field of mechanical engineering. These findings are important for the development of engineering components such as shafts and gears. This study aims to analyze the effect of quenching temperature variations on the hardness, tensile strength, and ductility of AISI 1045 steel experimentally. Heat treatment was carried out through samples up to an austenization temperature of 850°C with a holding duration of 30 minutes, followed by flash dipping (rapid cooling) using water media at temperature variations of 5°C, 15°C, 25°C, and 35°C. Each treatment was carried out five times and statistical analysis was given to obtain representative data. Observation of microstructures using serial light microscopy was carried out including evaluation. The results showed a close relationship between the decrease in coolant temperature and the increase in hardness and tensile strength. However, there is an opposite correlation with material durability. The highest hardness, 58 HRC, and the strongest tensile strength, 1250 MPa, were obtained for samples cooled at 5°C. Microstructure observations show a more dominant martensite formation at cooler immersion temperatures. The results of this study provide insight into the correlation with the transformation of the mechanical and microarchitectural characteristics of AISI 1045 steel.
