Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Fracture of drilling head pipe connection due to quenching of heat affected zone (HAZ)
The drilling head pipe connection is made of quenched and tempered steel 34CrNiMo6. The steel characteristic is high hardenability. Due to unsuitable and untested welding technology the heat affected zone (HAZ) cooling rate after welding surpassed the ...

Simulation of Distribution of Microstructures in Weld Heat Affected Zone [PDF]
publisherDistribution of microstructures in weld heat affected zone of multi-pass welded steel has large effect on, toughness of welded joints. Therefore, the method to estimate this distribution and the application of this method were investigated in ...

On the Brittleness of Heat-affected Zone (Report 5)
It is recognized that the impact-resistance of sharp-notched specimen decreases suddenly at the so-called "transition temperature". Below this temperature the fracture shows more brittle than shear one and at low temperatures the shear fracture vanishes.

Microstructural investigation of the heat-affected zone of simulated welded joint of P91 steel
In the process of testing real components exposed to elevated temperature, it is not possible to neglect cracks. The most significant cracks can be induced by welding, which is applied for joining of structural components.

Simulation of the weld heat affected zone of a 0.5Cr-Mo-V steel [PDF]
By using a Monte Carlo grain growth algorithm and a methodology for obtaining a one-to-one correlation between Monte Carlo and real parameters of grain size and time, the grain structure in the weld heat affected zone of a 0.5 Mo-Cr-V steel has been ...

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 ...
