TRIP steel annealed at 775°C for 5 mins and then hold at 400°C for 40s for austenite stabilization
The microstructure shows martensite (straw-coloured), retained austenite (white) and some M-A constituents. Martensite volume fraction is higher than the steel which was hold for 150s at 400°C and cooled. Since the austenite is low in C-content for such a low holding time at 400°C, most of the austenite is transformed to martensite during cooling from 400°C to room temperature.
The House of Affects Project
The House of Affects is an experimental installation to be part of the PerFormaSpace project pursued at the University of Cambridge, UK (DIGIS) and Goldsmiths College London, U.C.L. (Digital Studios), currently partially funded by Arts&Business East 2006, in collaboration with Econavate, UK who will provide their technical expertise in fabrication using recycled materials. This paper presents project-specific information and theoretical discussion on the design process and the computational meth
Simulating and assessing prospective scenariosA comparative approach in urban planning
The first part of the paper is centred on the phenomena of urban growth, in order to set the rules for a sustainable scenario of urban development. Then we enter the core of the paper that is the comparison of models. For each of the three compared models, we describe its main theoretical characteristics, the chosen parameters, and the obtained results. In section 6, heterogeneity of the produced results is discussed, and we highlight the points of interest and the lacks of the three models. Her
Pinhaldigital, estrutura mnem?nica e processos multim?dia nas fazendas de caf?: Hist?ria, arquitetur
This article has two aims, first to discuss the use of mnemonic structures in multimedia processes with complex contents in the example of the research project and activity PinhalDigital. Moreover it intends to describe the transdisciplinar method used for the production of the application, developing didactic extracurricular and interdisciplinary activities in the areas of history, architecture and technology through the use of multimedia construction processes. PinhalDigital was born of an ini
SiGradi2005: Vision and Visualization
Paradoxically, one of the most difficult but enjoyable things we do is to imagine. To open the eyes of our mind and see what no one else can see. We see images of things that are yet to be and through the same skill we devise ways in which to make them happen. We design the future in the form of environments, graphics, products, films, and a growing range of new media. Our ability to develop a vision and to visualize it is a gift that we are called to cultivate and put to good use. We have been
Experiments as Modus Operandi
Architecture has for too long focused on the presentation of pristine objects and the presentation in drawing form. A critical understanding of the field, however, necessitates a reevaluation of the roles of the process involved in the production of building. Rather than emphasizing surface appearances, an architecture rooted in process aims ultimately at revealing the fundamental and deep structures inherent within the making of architecture. One of the primary tasks of the process is to provok

The Academic Upgrade Program (.Capacitaci?n Docente.) is been developed in the contexto of a MECESUP project (government funding assignments for education) at the FAU of Universidad de Chile. This program is about upgrading knowledge and user capabilities in Information and Communication Technologies (IT) of our academic team, in order to improve our pedagogical model, and to include these IT into the learning-teaching process for Architecture, Design and Geography. Considering that new technolo
Design Tool Integration: Model Flexibility for the Building Profession
The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by s
How To Make A Digi-Brick
This project examines a non-traditional method of construction generated through a digital design process that leverages digital fabrication techniques related to masonry construction. Where as architects? use of computers first affected shape and structure, it is now additionally affecting material, construction, and craft. This design proposal explores these concepts through the production of a wall using simple configuration and reconfiguration of a repeated module adaptable to differing and
BIM and Integrated Practice as Provocateurs of Design Education
Building Information Modeling (BIM) obfuscates the role of composition, scale and abstraction by displacing the primacy of abstract conventions of representation with a methodology based on simulation. BIM subverts, while simultaneously clarifying, the holistic relationships of the parts to the whole in the architectural design of form and space. Architectural design education has great opportunity and risk in how it comes to terms with re-conceptualizing design education pedagogy as the profess
Brass, exhibiting grain boundary nucleation
A high zinc brass that forms large grains of β phase (yellow areas, due to higher copper content) and subsequently grains of γ form on β grain boundaries and also on non-metallic inclusions in the alloy.
Diagraphics: an expos? of visual expression
This expos? introduces preparations for a publication based on what I have found to be a ?missing link? in the library of educational source materials. The skills necessary to record and interpret the complexity of the architectural design process are often illusive. The sophistication of computer modeling and graphics applications only adds to the dilemma of making clear and concise decisions about how to communicate the essence of one?s design intent. The publication will define and illustrate

Our architectonical environment is based on the material concept - entity whose control marks the relevance of the XX century: the atom. Across the threshold of the XXI century a new virtual entity - concept: the bit, spreads to became the basic unit of power - control - production, being its more dynamic evidence the phenomenon known as Internet, establishing complex relationships with groups constituted in the net like Virtual Communities, outlining metaphors that involve Urbanists and Archite
Silal
This sample shows the typical structure of silal, irons with high Si content (5.5-7.9 wt%). It is a grey cast iron alloyed with 4-6wt% Si to provide good oxidation resistance. The high Si content forms a dense, adherent iron silicate surface film, which is resistant to oxygen penetration. The flake graphite iron Silal was one of the first heat resisting cast irons developed. Spheroidal graphite Si irons have higher strength and improved ductility. The structure shows cored dendrites of ferrite w

Grey cast iron
Cast iron with a high carbon content is referred to as grey cast iron since the carbon is present in the form of graphite flakes giving rise to a grey colour when viewed. This form of cast iron has several technologically useful properties such as good machinability, low melting temperature, good wear resistance and good mould reproduction.

Notes on the Synthesis of Form
Every design problem begins with an effort to achieve fitness between two entities: the form in question and its context. The form is the solution to the problem; the context defines the problem. We want to put the context and the form into effortless contact or frictionless coexistence, i.e., we want to find a good fit. For a good fit to occur in practice, one vital condition must be satisfied. It must have time to happen. In slow-changing, traditional, unselfconscious cultures, a form is adjus
As cast white cast iron
An example of a white cast iron, so named due to its relatively low carbon content, which means that the carbon present is in the form of cementite. Upon cooling the melt initially forms austenite dendrites and ledeburite. The dendrites then transform to pearlite, and the ledeburite to ferrite and cementite.
As cast white cast iron
An example of a white cast iron, so named due to its relatively low carbon content, which means that the carbon present is in the form of cementite. Upon cooling the melt initially forms austenite and subsequently graphite. Upon reaching the eutectoid temperature the austenite transforms to pearlite, giving a final microstructure consisting of graphite in a pearlite matrix.
