Spark plasma sintering in the presence of a liquid phase Mater. Lett. (IF 3.0) Pub Date : 2024-04-03 Dina V. Dudina, Nina Yu. Cherkasova
Spark plasma sintering (SPS) is a modern sintering technique based on the application of pulses of direct electric current and pressure to the powder sample. SPS is often regarded as a solid state sintering technique. At the same time, in many studies, the formation of a liquid phase during SPS was observed as an effect concurrent to the powder consolidation. Furthermore, in some cases, the formation

Crack healing via electropulsing treatment applied to additive-manufactured TiC/316L stainless steel composites Mater. Lett. (IF 3.0) Pub Date : 2024-04-03 Qing Cai, Pilar Rey Rodriguez, Sara Carracelas Santos, Gemma Castro, Chamini L. Mendis, Isaac T.H. Chang, Hamid Assadi
Three coupons of TiC/316L stainless steel composites were fabricated by laser-based directed energy deposition (DED-LB). One coupon is crack-free, and the other two coupons have cracks inside. Electropulsing treatment (EPT) was applied to heal the cracks, with various current densities and 75 pulses on each sample. The cracks with widths of 0–200 μm can be healed by EPT. The microstructure of the healed

Refined microstructure to improve the mechanical properties of the as-cast NiCoCr multi principal element alloy via mechanical vibration Mater. Lett. (IF 3.0) Pub Date : 2024-04-03 S.N. Lan, Y. Shi, J.Q. Yao, L.J. Xie, S.M. Yin, K. Wang, X.W. Liu
The NiCoCr multi principal element alloy (MPEA) show excellent ductility at cryogenic temperatures and corrosion-resistance properties under the condition that it prepared by thermal–mechanical processing. However, the coarse as-cast grains negatively impact mechanical properties significantly and grain refinement is necessary for forming complex castings. Most grain refining methods need extra alloying
