Trincas de solidificação em soldas num aço de construção naval

Machado, Ivan Guerra January 1980 (has links)
Comentado inicialmente o fato de que até hoje continuam altos os índices de falhas em estruturas soldadas e são mencionadas as trincas como uma de suas maiores causas, citando-se opiniões de reconhecidas autoridades no assunto. O termo "soldabilidade" é apresentado, sendo analisadas as dificuldades em precisar-se seu real significado, inferindo-se que ele é aplicável, com exatidão, somente para cada caso em particular. Explana-se as idéias fundamentais existentes com relação ao crescimento epitaxial e competitivo, realizando-se uma análise da influência dos parâmetros de soldagem sobre as estruturas de solidificação e microsegregação. Exemplifica-se a ação desse fenômeno sobre a formação das "Trincas a Frio na Zona do Metal Soldado", demonstrando-se a influência positiva de manipulação inteligente dos parâmetros "gradiente de temperatura no líquido" e "velocidade de crescimento do sólido" na solda, sobre a distribuição do hidrogênio. Numa pesquisa bibliográfica relativamente vasta, apresenta-se o estágio atual do conhecimento sobro o mecanismo e natureza das Trincas de Solidificação. Mostra-se suas características mais importantes, evolução histórica das pesquisas fundamentais para o desvendamento do suas particularidades e as teorias atualmente celtas quanto sua formação, todas elas indicando-se uma ação conjugada de deformação/microsegregação. Além disso, relata-se os fatores mais importantes relacionados com a suscetibilidade às Trincas de Solidificação, tanto sob o ponto de vista operacional, do lado "prático" da soldagem, quanto do prisma da ação dos elementos químicos, arrolando-se uma larga série de sugestões para minimizar essa suscetibilidade, assumindo vulto essas informações, pois são pouquíssimos e geralmente de abordagem superficial os trabalhos existentes sobre o assunto em língua portuguesa. Descreve-se e indica-se o uso dos ensaios mais usuais de soldadibilidade, relacionando suas várias categorias com os fenômenos das deformações e noções fundamentais de constrangimento das juntas soldadas. Discute-se, ainda, detalhadamente, a utilização do Teste Verestraint e suas variantes (Transvarestraint e Spot Varestraint), demonstrando-se as limitações de cada caso, além de discorrer-se sobre o fatos humano no problema. Apresenta-se, também, uma tabela que tenta englobar de maneira sintética os principais aspectos dos Testes vistos. Utilizando-se o Teste Varestraint, com TIG sem metal de adição, para estudar a suscetibilidade do metal base às Trincas de Solidificação, ale dos convecionais relaciomentos entre o Comprimento Total das Trincas médio, já que utilizamos sempre a média de no mínimo três ensaios com intensidade de corrente ou deformação, analisa-se o efeito da velocidade de soldagem, mantidos outros parâmetros constantes, o que sugeriu-nos uma interessante conclusão sobre o aspecto diferenciado, em relação à energia de soldagem, dos parâmetros corrente a velocidade. Através de análise metalográfica ótica e ao Microscópio Eletrônico de Varredura, discute-se aspectos característicos das Trincas de Solidificação, sendo que nesse último aparelho a trinca mostra-se de forma indiscutivelmente dendrítica, enquanto que os ataques utilizados em metalografica óptica permite-nos observar seu caminho intergranular, na estrutura secundária, ou, interdendrítico, quando a estrutura é primária. Estende-se o trabalho e avalia-se a influência do metal de adição proporcionado por dois processos distintos (MAG e Arco-Submerso), soldados superficialmente sobre a chapa e após fresado o excesso, sendo que, aparentemente, constata-se que o fator possível de ser relacionado com a sua suscetibilidade às Trincas de Solidificação é a razão fator de ser relacionado com a sua suscetibilidade às Trincas de Silidificação é a razão penetração/largura do cordão soldado, além de o metal base apresentar maior suscetibilidade às Trincas de Solidificação do que os metais de adição diluídos, dentro da faixa de trabalho utilizada.

The process of transition : becoming legitimate peripheral participants in the practice of seafaring

Bharatan, Ila S. January 2018 (has links)
My thesis seeks to develop the theory of legitimate peripheral participation by focusing on how it is accomplished in practice, through exploring the process of transition from novices to (relative) masters. In doing so, the study opens the black box of participation in studies of situated learning and focuses on two aspects that lead to a further development of legitimate peripheral participation. First, it looks at how newcomers undergo legitimate peripheral participation at two sites of practice and how movement between the sites influences the process of transition. Second, it focuses on the ways in which newcomers negotiate access to participation at a site where such access is not readily available. The research was conducted as a five-month multi-sited ethnographic study in the maritime industry; as such it focuses on the process of transition from cadets (newcomers) to officers (relative old-timers). Two research sites were used for conducting the ethnographic study, a maritime training center, and a merchant shipping vessel. Analysis of the data collected through observations and interviews at the two sites reveals key insights into the practical accomplishment of legitimate peripheral participation. The study shows the influence of movement between sites of practice and theorizes transition as an episodic process. Furthermore, the study explores the ways of doing through which newcomers are able to successfully negotiate access to participation. As such it develops a practice-sensitive concept of proactivity as a way of negotiating access to participation. Overall the thesis develops a more nuanced understanding of participation and shows how legitimate peripheral participation is accomplished in practice.

Image and imagination : perspectives on Athenian naval influence in the fifth century BC

Turner, Gordon R. B, n/a January 2007 (has links)
This thesis examines the Athenian navy in the fifth century BC from the standpoint of its image, in terms of perception and reputation, in comparison and contrast to its fact, in terms of actuality and truth. It investigates features of cultural history based around and arising from the contemporary state of mind about Athens� naval ships and sailors, from the points of view of Athenians and outsiders. Its hypothesis is that the supremacy of Athens� navy and the integrity of Athens� naval society in the fifth century were partly products of the Athenian imagination, and in turn gave rise to a reputation for Athens� navy and sailors that itself helped to fulfil Athens� naval and related tasks. Methodologically, the arguments of the thesis are developed 'from the inside out', as they are derived essentially from the primary sources, and then engage with secondary sources where appropriate. The approach is holistic, with source material derived principally from history, literature, art, architecture, and on-site analysis, with extensive illustrations. The thesis is expansive. It begins by examining the perception of Athens� naval supremacy and invincibility by Athenians and outsiders, and the impact that this had upon Athens� ability to achieve her naval and related objectives. It then looks inwardly upon Athens herself, in order to assess Athens� own social attitude towards her naval oarsmen and their base and home at the Piraeus. In this respect, the thesis investigates the development of artistic and literary depictions of the oarsmen of Athenian ships from the eighth to the fifth centuries, and the conclusions to be drawn from their visibility or its lack. It then considers the relationship between Athens and the Piraeus, beginning with the foundations of the image of unity before contrasting that image with the reality of naval division, in terms of Ionianism, autochthony, administration, politics, cult, and the deceit of Athenicity. The thesis then casts its net from the Piraeus across the Aegean Sea, by assessing the roles of Samos and Delos in the perception of naval Athens. Lastly, the thesis examines a topic that combines those of Athens� navy, the Piraeus, and overseas involvement. This topic is the importance of the reputations of Athens� navy and of the Piraeus in overseas trade with Athens� allies and particularly non-allies; and, including social and legal considerations, for influential Athenian citizens who wished to protect their investments in maritime loans for the transit of essential goods to Athens. The thesis concludes that the influence of the Athenian navy was indeed a product of image as much as of fact.
