An Investigation of the Suitability of Using AISI 1117 Carbon Steel in a Quench and Self-tempering Process to Satisfy ASTM A 706 Standard of RebarAllen, Matthew 11 August 2011 (has links)
Experiments were conducted to investigate the potential of using a quench and self-tempering heat treatment process with AISI 1117 steel to satisfy the mechanical properties of ASTM A 706 rebar. A series of quenching tests were performed and the resulting microstructure and mechanical properties studied using optical microscopy, microhardness measurement, and tensile tests. The presence of martensite throughout the samples contributed to the enhanced strength and strain-hardening ratio (tensile to yield strength) of the material. The experimental results showed that AISI 1117 is capable of meeting the ASTM standard. In addition to the experiments, a computer model using the finite difference method and incorporating heat transfer and microstructure evolution was developed to assist in future optimization of the heat treatment process.

Werbung für Weimar?Bonte, Achim 14 February 2013 (has links) (PDF)
Das Werk ist die leicht überarbeitete Fassung der Dissertation, die 1995 mit dem Titel "Kommunalverwaltung und Verfassungswandel. Öffentlichkeitsarbeit von Großstadtverwaltungen in der Weimarer Republik" eingereicht wurde.
Die Studie beschäftigt sich mit der nach der Revolution von 1918/19 erstmals breit institutionalisierten großstädtischen Öffentlichkeitsarbeit. Sie untersucht Umfang, Medieneinsatz und Kommunikationsstile sowie die zentralen Botschaften der Rathausinitiativen. Der Leser erhält Aufschluß über die politischen Auffassungen und Prinzipien der kommunalen Spitzenbeamten und die Haltung der großen Kommunalverwaltungen zur Weimarer Republik. Als konkrete Beispiele werden in erster Linie Düsseldorf und Mannheim herangezogen.
