Microstructure of interpass rolled wire + arc additive manufacturing Ti-6Al-4V components [PDF]

, 2015
Mechanical property anisotropy is one of the issues that are limiting the industrial adoption of additive manufacturing (AM) Ti-6Al-4V components. To improve the deposits’ microstructure, the effect of high-pressure interpass rolling was evaluated, and a

Hot Deformation Behavior of Alloy AA7003 with Different Zn/Mg Ratios

Metals, 2022
The hot-deformation behavior of three medium-strength Al-Zn-Mg alloys with different Zn/Mg ratios was studied using isothermal-deformation compression tests; the true strain and true stress were recorded for constructing series-processing maps.

Influence of heating parameters on flow stress curves of low-alloy Mn-Ti-B steel [PDF]

, 2018
Influence of the initial grain size on hot deformation behavior of the low-alloy Mn-Ti-B steel was investigated. The uniaxial compression tests were performed in range of the deformation temperatures of 900-1200 degrees C and strain rates of 0.1-10 s(-1).
