United States Steel Corporation (USS) industrial research engineers used neutrons at Oak Ridge National Laboratory’s Spallation Neutron Source to analyze materials exposed to different manufacturing processes.

“Because this is a new material containing retained austenite, we need to have a better understanding of its performance. A better understanding of how this material responds to different manufacturing processes like stamping or hydroforming will help us validate engineering models that will in turn make it easier to design and produce auto components that are lighter, stronger, and more durable.” ~ Lu Huang, USS industrial research engineer

Surgical medicine has for years depended upon stainless steel for medical devices such coronary stents, hip-implant stems, and spinal-disc replacements, for a variety of surgical tools such as scalpels and forceps, and for operating tables. However, allergic and toxic reactions that trigger rejection by the body have driven researchers to develop a stainless steel component that will resist the buildup of harmful bacteria, among other flaws.

Scientists at Université de Montréal’s Faculty of Dental Medicine, along with a colleague from the Department of Chemistry, have discovered a way to improve the efficacy of stainless steel by changing its surface through the creation of a nanoscale network of pores — a process called nanocavitation.

Researchers from the Singapore Institute of Manufacturing Technology and Nanyang Technological University have devised a method that involves heat treatment processes to strengthen magnesium alloy and produce a more workable, ultra-fine crystalline structure suitable for multiple applications, including aerospace, automotive, transportation, medical and technology.

“By optimizing the processing temperature and strain rate, we were able to achieve an ultrafine-grained microstructure, which does not physically change the alloy, but improves its mechanical properties through grain refinement,” reported Kai Soon Fong, Senior Research Engineer at Singapore Institute of Manufacturing. “This processing led to improved mechanical strength and ductility, making it tougher and easier to shape at room temperature.”

Researchers at Toyohashi University of Technology have collaborated with their counterparts at Massachusetts Institute of Technology (MIT) to develop a new material capable of retaining high transmissivity after annealing at 850°C (1562°F). The results address the challenge manufacturers face when combining different materials that react differently to heat treatment at certain temperatures.
