Refining of Intermediate Transformation Microstructure by Relaxation Processing.

ISIJ International, 2002
The influence of RPC (relaxation-precipitation-controlling phase transformation) processing parameters on the microstructure was studied by thermo-simulation for a low carbon Nb and Ti containing microalloyed steel. The semi-quantitative statistic work of the packet size was carried out by the aid of optical microscope.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Optimizing calcium additions for a strength-corrosion resistance balance in squeeze-cast Zn-Al-Cu-Mg alloys [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
In this study, squeeze-cast Zn–Al–Cu–Mg alloys with varying Ca additions (0, 0.5, 1.0, and 1.5 wt.%) were investigated to evaluate the combined effects of microstructural evolution on mechanical and corrosion performance.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

Advanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Texture and grain refinement for enhanced strength and ductility in friction stir welding of cold-rolled thin-strip rapidly solidified AA5182 Al–Mg alloy

Journal of Materials Research and Technology
Thin-strip (TS) casting enhances Al–Mg alloy production by rapidly solidifying strips, resulting in finer grains, higher solute supersaturation, and fewer intermetallic phases making it ideal for automotive and packaging industries.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.
