As-cast wrought-grade aluminium alloy
The micrograph shows Al-Mg-Fe-Si containing < 1wt.% of each solute. Addition of TiB2 particles facilitates the formation of a fine, equiaxed grain structure (grain refinement). This micrograph illustrates one of the possible growth morphologies that a solidifying metal can adopt (c.f. micrograph 711). The grains in this structure exhibit no dendritic branching, i.e. the solid-liquid interfaces of the growing grains are smooth. When a solid grain is growing from the liquid phase, it will initiall
IN718 nickel-based superalloy held for 20 minutes at 850°C
IN718 is a nickel-based superalloy composed of approximately 53 wt% Ni, 19 wt% Fe, 18 wt% Cr, 5 wt% Nb, and small amounts of Ti, Mo, Co, and Al. The alloy has a number of distinct phases present in its microstructure. These are namely the matrix, γ, and the precipitates, γ', γ'', and δ. The primary strengthening phase is γ'' [1], the composition of which is Ni3Nb. It has a body-centred tetragonal structure, and forms semi-coherently as disc-shaped platelets within the γ matrix, having t

High tractive power wall-climbing robot
There are a lot of tasks in building construction and maintenance which demand either the carriage of heavy technological equipment along vertical and sloping surfaces and/or provision for force technological operations on such surfaces For example, surface cleaning or grinding by automatic equipment, the mounting of expansion bolts and anchors by drilling or by driving in. Additionally surface inspection by heavy measuring devices and the painting of big construction areas are difficult and exp

Architecture and the Culture of Contingency
A culture is a set of behaviours, attitudes and values that are shared, sustained and transformed by an identifi able community. Currently, we are bound up in a culture of consumerism, and of terror; there are also retro cultures and utopian cultures. What?s happening now that?s interesting is that many, if not all of these diff erent tendencies, tastes and persuasions are being re-aligned, interconnected and hybridised by a vast global community of online users, who are transdisciplinary in the
Modeling architectural design objectives in physically based space planning
Physically based space planning is a means for automating the conceptual design process by applying the physics of motion to space plan elements. This methodology provides for a responsive design process, which allows a designer to easily make decisions whose consequences immediately propagate throughout the design. It combines the speed of automated design methods with the flexibility of manual design methods, while adding a highly interactive quality and a sense of collaboration with the desig
