10083-3:2006. 34CrNim06 steel has high strength, high toughness and good
hardenability. EN / DIN 34CrNiMo6 alloy steel has the stability of
resistance to overheating, but the white sensitivity of 34CrNiM06 is
high. It also has the temper brittleness, so the weldability of
34CrNiMo6 material is poor. The steel 34CrNiMo6 needs the high
temperature preheating before welding in order to eliminate the stress
after welding processing.

Technology tends to move toward the bigger and better, cramming more and more features into a given product. But sometimes, less is more.
Robots are often called on to do the jobs that are too dirty or dangerous for humans, such as examining the Fukushima Daiichi nuclear power plant after it experienced multiple meltdowns in the wake of a tsunami. The most advanced robots, however, were stymied by the same problems as their human counterparts; the massive amounts of radiation inside would make it a one-way trip. Smaller, simpler robots are now being developed with such applications in mind.
Researchers at the University of Pennsylvania’s School of Engineering and Applied Science have now taken this effort a step forward, debuting the world’s smallest self-powered controllable flying vehicle: Piccolissimo.
Italian for “tiniest,” Piccolissimo is the brain child of Matt Piccoli, a graduate student in professor Mark Yim’s ModLab. The robot comes in two sizes; the smaller weighs less than 2.5 grams and is about the width of a quarter, while the larger, steerable version is about 2 grams heavier and a centimeter wider.
The string of adjectives qualifying Piccolissimo as the “smallest” is necessary due to the concerted effort in miniaturizing flying robots. Harvard’s RoboBee, for example, is a few millimeters smaller than the steerable Piccolissimo, but is tethered to a terrestrial power source, limiting its range of motion.
Enabling directional control on such a tiny frame is an equally big challenge, but one that the ModLab is particularly equipped to address. One of the lab’s specialties is “underactuated” robots, ones that achieve the greatest range of motion with the fewest motors possible.
A lecture given by K. Fang, at the Adventures in the Physical Metallurgy of Steels (APMS) conference held in Cambridge University. Nanostructured bainite is incredibly difficult to weld because of its high carbon concentration. Here an innovative method is presented to resolve the weldability. The presentation file can be downloaded from http://www.msm.cam.ac.uk/apms/
High-carbon nanostructured bainite steel is very difficult to be well welded due to poor weldability. By adopting a new technology called regeneration treatment, the welded joint has similar microstructures and mechanical properities to base metal. The effect of regeneration time (0h-120h) and temperature (230Â°C-270Â°C) on microstructures and mechanical properities was also investigated.
Results show that microstructures in fusion and austenitised zones consist of two phases when regeneration time is long enough, which are nano-scale bainite ?lms separated by carbonâ€”enriched ?lms of retained austenite. However, volume fraction of retained austensite in fusion zone is a little lower than austenitised zone. With regeneration temperature increasing, volume fraction of retained austensite increases and thickness of slender platelets shows the same changing trend. The changes of microstructures have important effect on mechanical properities. By tensile and hardness test, the strength of fusion zone is lower than austenitised zone, but both increases with regeneration temperature decreasing while the elongation decreases. And the micro hardness increases when regeneration temperature decreasing. The strength of obtained welds reaches to as high as 1.7-2.1 GPa and corresponding hardness 550HV-650 HV.
