Effect of Zr Additions on Thermal Stability of Al-Cu Precipitates in As-Cast and Cold Worked Samples

Metals, 2018
While Zr is frequently added to Al alloys to control grain size with the formation of large (>1 μm) primary precipitates, little research has been conducted on the effect of nanoscale Al3Zr precipitates on Al alloys. By comparing the precipitation and

STRENGTHENING CONTRIBUTIONS OF STRONG ORDERED PRECIPITATES [PDF]

Philosophical Magazine A, 1987
Abstract The Hanson-Morris solution for the critical resolved shear stress of a random array of point obstacles is modified and applied to strong ordered precipitates. The solution approximately accounts for the effects of dislocation self-interactions and elastic anisotropy.

Influence of Vanadium on the Microstructure and Mechanical Properties of Medium-Carbon Steels for Wheels

Metals, 2018
Steels used for high-speed train wheels require a combination of high strength, toughness, and wear resistance. In 0.54% C-0.9% Si wheel steel, the addition of 0.075 or 0.12 wt % V can refine grains and increase the ferrite content and toughness ...

Strengthening of stainless steel weldment by high temperature precipitation [PDF]

, 2017
The mechanical behavior and the strengthening mechanism of stainless steel welded joints at 600 °C have been investigated. The welds were composed of AISI 304 stainless steel, as base metal, and niobium containing AISI 347 stainless steel, as weld metal.
