Thermo-mechanical finite element analysis incorporating the temperature dependent stress-strain response of low alloy steel for practical application to the hot stamped part
TL;DR: In this article, the authors measured the isothermal stress-strain responses of a low alloy steel sheet at elevated temperature, which simulates the material response in the hot stamping process, were measured by the Gleeble3500 thermo-mechanical simulator.

Microstructures and mechanical properties of surface and center of carburizing 23Cr2Ni2Si1Mo steel subjected to low-temperature austempering
TL;DR: In this paper, a multiphase microstructure composed of nano-scaled bainite, martensite, undissolved spherical carbides and retained austenite was obtained on the top surface of carburizing 23Cr2Ni2Si1Mo steel after low-temperature austempered at 200°C.

Inverse heat conduction analysis of quenching process using finite-element and optimization method
TL;DR: In this article, a new method to calculate the temperature-dependent surface heat transfer coefficient during quenching process is presented, which applies finite-element method (FEM), advance-retreat method and golden section method to the inverse heat conduction problem, and can calculate the surface heat transferred coefficient according to the temperature curve gained by experiment.
