ätten microstructure

Description

This sample has been air cooled. The fast cooling rate changes the morphology to a 'basket weave' appearance known as a Widmanstätten microstructure. The ? phase precipitates out of the single ? phase during cooling to give ? plates in a ? matrix. The plates form in order to minimise strain energy.

Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE)

Description

FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor. In this case, grains of 1-4mm diameter have been sintered at 600 degrees C for just 10 minutes, giving rise to lightly interconnected, angular pores. Wash out is slow, and can be improved by longer sintering which gives thicker necks between salt grains and hence more interconnection of pores in the reticulated structure.

'Kosmaj' afloat after launch

Description

?Kosmaj? afloat after launch by Sunderland Shipbuilders Ltd and the North Sands shipyard, 18 August 1977 (TWAM ref. DS.JLT/4/PH/2/7). The shipyard did a remarkable job of replacing the bottom structure of the vessel after much of it was destroyed by fire in March 1977. Tyne & Wear Archives is proud to present a selection of images from its Sunderland shipbuilding collections. The set has been produced to celebrate Sunderland History Fair on 7 June 2014. It's a reminder of the thousands of vessels launched on the River Wear and the many outstanding achievements of Sunderland?s shipyards and their workers. These photographs reflect Sunderland?s history of innovation in shipbuilding and marine engineering from the development of turret ships in the 1890s through to the design for SD14s in the 1960s. The Sunderland shipbuilding collections are full of fascinating stories. Some of these are represented in this set, such as the ?Rondefjell?, launched in two halves on the River Wear by John Crown & Sons Ltd and then joined together on the River Tyne. The set also shows the vital part that Sunderland?s shipbuilding industry played during the First World War. William Doxford & Sons Ltd built Royal Naval destroyers such as HMS Opal, which served in the Battle of Jutland, while other yards constructed cargo ships to help keep these shores supplied.

CMS.603 American Soap Operas (MIT)

Description

The television landscape has changed drastically in the past few years; nowhere is this more prevalent than in the American daytime serial drama, one of the oldest forms of television content. This class examines the history of these "soap operas" and their audiences by focusing on the production, consumption, and media texts of soaps. The class will include discussions of what makes soap operas a unique form, the history of the genre, current experimentation with transmedia storytelling, the online fan community, and comparisons between daytime dramas and primetime serials from 24 to Friday Night Lights, through a study of Procter & Gamble's As the World Turns.

CMS.405 Media and Methods: Seeing and Expression (MIT)

Description

In this course students create digital visual images and analyze designs from historical and theoretical perspectives with an emphasis on art and design, examining visual experience in broad terms, and from the perspectives of both creators and viewers. The course addresses key topics such as: image making as a cognitive and perceptual practice, the production of visual significance and meaning, and the role of technology in creating and understanding digitally produced images. Students will be given design problems growing out of their reading and present solutions using technologies such as the Adobe Creative Suite and/or similar applications.

°C - Widmanstätten microstructure

Description

This sample was quenched and held at 300 °C for one hour. It has a Widmanstätten microstructure with the ? phase precipitating out of the single ? phase during cooling to give ? plates in a ? matrix. The low temperature at which the transformation takes place leads to less diffusion and results in a finer structure.

White cast iron, subject to slow heating and cooling treatment

Description

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.
