This thesis is divided into four sections. The first chapter deals with Mamlūk historiography and its major characteristics, alongside an examination of the life al' Aynī's, who was one of the most prominent historians of the period. Special attention is paid to his professions, masters, students as well as his numerous works. Chapter two, on the other hand, focuses on the copies of 'Iqd al-jumān fi tārīkh ahl al-zamān, mentioning the published volumes that covered most of the Ayyūbid and Mamlūk eras. The rest of this chapter deals with the methodology used in the edition of Volume eleven (431-520/1040-1126) as well as demonstrating its importance and sources. Chapter three presents an edition of the Arabic text of Volume eleven. Chapter four is a separate volume, which initially deals with the life and works of the historian Muḥammad b. 'Abd al-Malik al-Hamadhānī. The rest of chapter examines the historical fragments from his lost historical book, called 'Unwān al-siyar fī maḥāsin ahl al-Badū wa'-l Ḥaḍr, also known as Al-Ma'ārif al-muta'akhkhira: these fragments are to be found in Volume eleven of the 'Iqd al-jumān. At the end of this chapter, the Arabic text is reconstructed and its biographical materials, are reorganised in alphabetical order.

This is a study of Jalāl al-Dīn al-Suyūṭī’s al-Durr al-manthūr fi-l-tafsīr bi-l-ma’thur (The scattered pearls of tradition-based exegesis), hereinafter al-Durr. In the present study, the distinctiveness of al-Durr becomes evident in comparison with the tafsīrs of al-Ṭabarī (d. 310/923) and Ibn Kathīr (d. 774/1373). Al-Suyūṭī surpassed these exegetes by relying entirely on ḥadīth (tradition). Al-Suyūṭī rarely offers a comment of his own. Thus, in terms of its formal features, al-Durr is the culmination of tradition-based exegesis (tafsīr bi-l-ma’thūr). This study also shows that al-Suyūṭī intended in al-Durr to subtly challenge the tradition-based hermeneutics of Ibn Taymīyah (d. 728/1328). According to Ibn Taymīyah, the true, unified, interpretation of the Qurʼān must be sought in the Qurʼān itself, in the traditions of Muḥammad, and in the exegeses of the earliest Muslims. Moreover, Ibn Taymīyah strongly denounced opinion-based exegesis (tafsīr bi-l-ra’y). By means of the traditions in al-Durr, al-Suyūṭī supports several of his views in contradistinction to those of Ibn Taymīyah. Al-Suyūṭī’s traditions support the following views. First, opinion-based exegesis is a valid supplement to tradition-based exegesis. Second, the early Muslim community was not quite unified. Third, the earliest Qur’ānic exegetes did not offer a unified exegesis of the Qur’ān. Fourth, Qur’ānic exegesis is necessarily polyvalent since Muslims accept a number of readings of the Qur’ān, and variant readings give rise to various interpretations. Al-Suyūṭī collected his traditions from a wide variety of sources some of which are now lost. Two major exegetes, al-Shawkānī (d. 1250/1834) and al-Ālūsī (d. 1270/1854), copied some of these traditions from al-Durr into their Qur’ān commentaries. In this way, al-Suyūṭī has succeeded in shedding new light on rare, neglected, and previously scattered traditions.

Neste trabalho foram obtidas barras da liga (Fe0,80Al0,20)97B3 por solidificação direcional (SD), nos diâmetros de 3 e 4 mm, com o objetivo de melhorar a magnetostricção desse material através da introdução de textura. As etapas de produção das barras envolveram a fabricação de lingotes da liga por fusão a arco L1, L2 e L6, seguida de usinagem (U) ou forjamento rotativo (F) a quente. O maior comprimento de barra obtido foi de 50 mm. Através de microscopia eletrônica de varredura e análise de composição por espectroscopia de energia dispersiva, detectou-se a presença de boro nas amostras pela visualização do microconstituinte eutético formado da fase ? e da fase Fe2B. Resultados obtidos por difração de raios X indicam que a amostra da liga L1 para o diâmetro de 4 mm apresentou orientação preferencial nas direções , o que causou uma diminução expressiva da magnetostricção se comparada a da amostra do mesmo lingote para o diâmetro de 3 mm. Medidas de magnetização em função do campo magnético aplicado (Ha) indicaram que a magnetização de saturação das amostras que têm boro são em média 181 Am2/kg, sugerindo que as amostras tem ~ 2% de B. A barras obtidas por SD, tratadas termicamente (CTT) a 1100°C por 6 h, alcançaram uma maior magnetostricção (? = ?l/l), comparada as amostras sem tratamento térmico (STT), no qual o maior valor foi de 73 ? 10-6 na direção longitudinal da barra L1 forjada no diâmetro de 3 mm (L1F3-CTT). O maior fator de sensibilidade d?/dH obtido em função do comprimento da barra L1F3 foi de d?/dH = 0,9 x 10-9 m/A para a razão de aspecto ? = 12. Valor da constante anisotrópica K1 calculada a partir dos resultados experimentais se comparadas com dados da literatura, sugerem que em algumas amostras ocorre ordenamento parcial da fase cúbica da matriz, havendo assim a coexistência das fases Fe3Al (D03) e ?. / In this work, bars of the alloy (Fe0,80Al0,20)97B3 were obtained by directional solidification (DS) in diameters of 3 and 4 mm, with the goal of improving the magnetostriction of the material through the introduction of texture. Production steps of the bars involved the manufacture of the alloy ingots, L1, L2, L6, by arc melting, then machining (M) or hot swaging (F). The greatest length that was achieved in a bar was 50 mm. The presence of boron in the samples was identified by scanning electron microscopy and energy dispersive spectroscopy, due to the presence of an eutectic microstructure that has dendrites and a microconstituent formed of phases ? and Fe2B. Results obtained by X-ray diffraction indicates that the bar L1 at the diameter of 4 mm showed preferential orientation in the directions , which caused a significant decrease of the magnetostriction compared to the same sample of the bar of diameter 3 mm. Magnetization measurements as a function of applied magnetic field (Ha) reveal that the saturation magnetization of the samples having boron is in average 181 Am2/kg, suggesting that the samples have ~ 2% of boron. The bars obtained by DS, thermally treated (CTT ) at 1100 ° C for 6 h, achieved higher magnetostrictions (? = ?l/l) compared to the samples without heat treatment.The highest value was 73 ? 10-6 was obtained in the longitudinal direction of the bar L1F in the diameter of 3 mm (L1F3-CTT). The maximum sensitivity factor d?/dH found as a function of the bars lengths was d?/dH = 0.9 x 10-9 m/A for an aspect ratio of ? = 12. Values of anisotropic constant K1, calculated using experimental results suggest that in some samples occur partial ordering of the cubic phase matrix , so there is the coexistence of phases Fe3Al ( D03 ) and ?.
