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...
