Even though quite a few alloys are now known to be able to get improved mechanical properties through precipitation hardening (Fig.
The strength profile for AlSiMg alloys with magnesium concentrations have shown a steep increase in yield strength through the precipitation hardening, a subsequent plateau with the final peak value, followed by a slow decrease in yield strength due to over aging, according to measured and simulated results (Fig.
Since the AA6181 is a precipitation hardening alloy, the changes of the precipitates during and after welding will be the most important phenomena dictating the resulting hardness and strength of the different weld zones.
Their topics include thermodynamic calculations for quantifying the phase fraction and element partition in maraging systems and precipitation hardening steels, quantifying phase transformation kinetics and age hardening, over-ageing, precipitation hardening stainless steels, and applying artificial neural networks in the modeling of steel properties.
Tear strength will increase due to the increased path length for the crack to follow--akin to precipitation hardening in metals.
has received a patent for an article having on at least a portion of its surface a multi-layer coating having the appearance of brass, nickel and stainless steel comprised of a base-coat layer; an oxide containing strike layer comprised of a refractory metal and a low percentage of refractory oxide rendering a nano-size refractory metal crystals or oriented refractory metal phase with the refractory oxide acting as precipitation hardening particles; a chrome layer intermediate the basecoat layer and the oxide strike layer; a stack layer comprised of alternative layers of refractory metal, substoichimetric refractory nitride and stoichiometric refractory nitride; an intermediate refractory oxide layer between the oxide strike layer and the stack layer; and a refractory nitride color layer.
