To realize cross-wedge rolling of shaft parts without a stub bar in a short process, an axial closed–open-type cross-wedge rolling technique was proposed. Base
With the growing demand for energy saving, emission reduction, and green metallurgy, we had designed a new C–H2 smelt-ing reduction reactor. In order to solve
The weldability of 0.28C–2.0Mn–0.93Al–0.97Si (wt.%) transformation induced plasticity (TRIP) steels was investigated using a 2.5 kW CO2 laser at the welding s
