Date Received: 25 September, 1997 Accepted: 12 December, 1997 Introduction Before I expose my subject, I would like to pay tribute to the memory of Dr. Brock Chisholm, first Director-General of the World Health Organization, whose memory inspired the establishment of this lecture. Those who did so obviously hoped to create a chain of inspiration leading from the root of the Organization into th...

Semi-solid processing (SSP) is a popular near-net-shape forming technology for metals, while its application is still limited in titanium alloy mainly due to its low formability. Recent works showed that SSP could effectively enhance the formability and mechanical properties of titanium alloys. The processing parameters such as temperature and forging rate/ratio, are directly correlated with th...

Labour economics is often taken by vivid discussions about the specificity of the labour market and the need to develop a different approach, away from the current standard microeconomics. What is often forgotten is that this was not always the case. Labour research in the interwar years was quite different from what we regard presently as labour economics, being much more broadly and loosely d...

The nickeland iron-aluminide alloys are an important class of materials because of their unique resistance to oxidizing, carburizing, and sulfidizing environments at high temperatures. They also provide an interesting combination of high-temperature strength and wear resistance. Many applications have been identified for these materials including: furnace fixtures, heating elements, pumps, hydr...

Abstract Forgings are produced in several process steps, the so-called forging sequence. The design of efficient sequences is a very complex and iterative development process. In order to automate this reduce time, method presented here, which automatically generates multi-stage for different geometries on basis component geometry (STL file). was developed closed die forging. individual modules...

In a closed die forging process, it is impossible to form complex shapes in one stage, and thus it becomes necessary to use preform dies. In the present study, Backward Deformation Method and FE simulation via ABAQUS software has been used in order to design preform die of the H-shaped parts. In the Backward Deformation Method, the final shape of the part is considered as a starting point and u...
