Investigating Complex Geometrical Features in LPBF-Produced Parts: A Material-Based Comparison Between Different Titanium Alloys
No full textThe Ti–6Al–4V (Ti64) alloy is a well-established material to be processed via laser powder bed fusion (LPBF). Recently,
other α + β titanium alloys are receiving attention, such as Ti–6Al–2Sn–4Zr–6Mo (Ti6246). Their typical industrial fields of
application (aerospace, automotive), often require critical design choices, such as low wall thicknesses and hollow channels.
Thus, a comparative analysis between these two competitor alloys in terms of processability was conducted in this work.
To do so, specific sample designs were developed. The specimens were analyzed in terms of geometrical compliance with
the initial design, porosity, and microstructure. A correlation between the width of the specimens and their porosity, micro-
structure and hardness was found. Overall, both the alloys proved to be well processable, even for very low wall thickness
(300 μm) and channel diameter (1 mm) values. Nevertheless, the Ti6246 alloy seemed to behave better in specific scenarios.
For instance, some Ti64 specimens provided delamination. The hollow channels proved to be challenging for both materi-
als, mainly due to the high amount of residual powder particles adhered to the upper part of the holes. This works aims at
giving a materials perspective on process-related issues, considering the LPBF-induced defectology and microstructural
variations in these Ti alloys

Vegetarisk (rå)kost och det reformerade livet : Maximilian Bircher - Benner och de svenska hälsokoströrelserna
No full textRaw vegetarian food and life reform: Maximilian Bircher-Benner and the Swedish health foods movements. By Motzi Eklöf. Movements for life reform, natural healing, and health foods have persisted in Sweden since the last decades of the 19th century. Stressing the importance of less alcohol and other drugs, a proper diet, and the use of natural healing methods, they have displayed conflicts concerning individual rights to decide in matters concerning one’s own body and health in relation to a medicine and state demands. Swedish movements for natural healing and health foods have developed under influence from leading figures and movements in Sweden, Germany, Switzerland, North America, and England. In 1900, the Swiss physician Maximilian Bircher-Benner (1867–1939) launched his theory of ”sunlight food”, meaning that uncooked vegetables and fruits were containing the most energy, whereas meat was radically less nourishing. His theories were contrary to contemporary medical and bourgeois culture considering meat as the optimum food, at least for real men. He became an outsider in medicine until the discovery of vitamins in the 1920s lent him some support. His clinic ”Lebendige Kraft” in Zürich received well-to-do clients from all over the world; these were treated with different physical methods, raw vegetarian food, and proper routines for day and night. Stressing the importance of raw vegetarian food, Bircher-Benner influenced vegetarians and food reformers in Sweden during the 20th century. In the 1930s, especially women with connections to the Swedish vegetarian association, founded in 1903, recommended his philosophy of food and natural healing. Menus copied from his books were used in health resorts, vegetarian pensions, and restaurants. But during the decades around World War II, Are Waerland dominated the Swedish health-food scene, demanding adherence to his very restrictive health food programme. The post-war health movements drew on both Waerland and Bircher-Benner in their food recommendations. This article proposes factors facilitating or counteracting a broader acceptance of Bircher-Benner’s ideas in Sweden. Health resorts and strong lay traditions in the health care field have maintained a tradition of non-invasive and non-pharmacological healing methods. A strained relationship between medical doctors and lay vegetarian spokesmen have made a more serious discussion of the topic difficult. Political associations tied to natural healing in Germany during the 1930s have affected the debate and have probably also restrained a broader acceptance of these ideas. Today, scientific studies have resulted in official nourishment recommendations similar to a previously launched ”health food”
