The Correlation Between Grain Orientation Evolution and Stress Rupture Properties of Waspaloy
The grain orientation evolution of Waspaloy with different initial grain sizes under the same stress rupture tests were systematically investigated by electron back-scattered diffraction (EBSD). Correlation b...

Constitutive behavior and processing maps of low-expansion GH909 superalloy
The hot deformation behavior of GH909 superalloy was studied systematically using isothermal hot compression tests in a temperature range of 960 to 1040°C and at strain rates from 0.02 to 10 s−1 with a height red...

Effects of simulated on-fire processing conditions on the microstructure and mechanical performance of Q345R steel
A series of simulated on-fire processing experiments on Q345R steel plates was conducted, and the plates’ Brinell hardness, tensile strength, and impact energy were tested. Microstructure morphologies were sys...

Mechanism of α-Cr precipitation and crystallographic relationships between α-Cr and δ phases in Inconel 718 alloy after long-time thermal exposure
To study the precipitation mechanism of α-Cr phase in Inconel 718 alloy, the samples after long-time aging at 650 and 677°C were examined by microstructural observations and chemical phase analysis methods. Co...
