A new paper in « Case study in Engineering Failure Analysis » published on ScienceDirect.com.

This paper describes cracking of turret terminals made of free cutting brass during swaging operation. The crack propagation tendency during cold working of brass turret terminals made from different compositions is studied through optical and scanning electron microscopy. Finally, composition for obtaining crack free terminals during swaging is suggested for applications involving cold swaging.

Thesis WorkA Thesis work of  Högskolan Dalarna, Falun, Sweden online on http://www.diva-portal.org/.

This work has had the purpose to examine defects and the cause of crack growth during long termstorage in rolled bars. The bars in question are rolled and stored at Ovako in Hofors. The problem is approached by theoretically examining the possibilities of hydrogen damage, room temperature creep and naturally occurring porosity.
