Refinement of Techniques Metallographic Analysis of Highly Dispersed Structures
Journal of Physics: Conference Series, 2016 Flaws are regularly made while developing standards and technical specifications. They can come out as minor misprints, as an insufficient description of a technique. In spite the fact that the flaws are well known, it does not come to the stage of introducing changes to standards.

Effects of Cooling Rate on Metallographic Structure and Hardness of Bearing-B Steel [PDF]
Proceedings of the 2nd International Conference on Electronic and Mechanical Engineering and Information Technology (2012), 2012 Effects of cooling rate on metallographic and hardness of bearing-B steel were investigated in present research. The results showed it consists of ferrite and pearlite formed in the initial stage of the transformation in the studied bearing-B steels cooled at 0.5 °C/s.

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
