Age hardening heat treatment behavior of as-cast Mg–Zn–Al alloys

Effect of Be, Zr and Heat Treatment on Mechanical Behavior of Cast Al-Mg-Zn-Cu Alloys (7075)

The present study was undertaken to investigate the effect of aging parameters (time and temperature) on the mechanical properties of Be-and/or Zrtreated Al-Mg-Zn (7075) alloys. Ultimate tensile strength, 0.5% offset yield strength and % elongation measurements were carried out on specimens prepared from cast and heat treated 7075 alloys containing Be and/or Zr. Different aging treatment were c...

Cooling – As a “Heat Treatment” for the Mechanical Behavior of the Bulk Metallic Glass Alloys

High-strength age hardening copper–titanium alloys: redivivus

In this review the decomposition of supersaturated Cu–Ti solid solutions and subsequent microstructural evolution are discussed in terms of modern views of precipitation from solid solution. This update is motivated by an anticipated emergence of these alloys as technologically significant high-strength, high-conductivity, precipitation hardened alloys over the next decade replacing conventiona...

Fluidized Bed Heat Treatment of Cast Al-Si-Cu-Mg Alloys

The effects of fluidized bed heat treatment on the microstructural and mechanical properties of Al-Si-Cu-Mg cast alloys, namely,3 54 and 319, were studied. The heating rate in fluidized beds (FBs) is greater vis-a`-vis conventional electrical resistancef urnaces (CFs). The high heating ratei nF Bs increases the kinetics of metallurgical phenomena such as Si fragmentation and spherodization duri...
