Pyrolysis characteristics and thermal kinetics of expanded polystyrene (EPS) and styrene-methyl methacrylate (St-MMA) copolymer in LFC process
Autor: Xi Li, Ya-jun Yin, Jian-xin Zhou
Publikováno v: China Foundry, Vol 15, Iss 6, Pp 428-435 (2018)
The pyrolysis behaviors of foam patterns have critical infl uences on fl uid morphology and defect formation in Lost Foam Casting (LFC). The pyrolysis behaviors of expanded polystyrene (EPS) and styrenemethyl methacrylate (St-MMA) foams were compar

Temperature field simulations during selective laser melting process based on fully threaded tree
Autor: Wei Duan, Ya-jun Yin, Jian-xin Zhou
Publikováno v: China Foundry, Vol 14, Iss 5, Pp 405-411 (2017)
Selective laser melting (SLM) is a promising technique for additive manufacturing. During SLM of metallic powder, the temperature field and thermal history are important to understand physical phenomena involved. The purpose of this study is to simul

Multi-scale coupling simulation in directional solidification of superalloy based on cellular automaton-finite difference method
Autor: Zhao Guo, Jian-xin Zhou, Ya-jun Yin
Publikováno v: China Foundry, Vol 14, Iss 5, Pp 398-404 (2017)
Casting microstructure evolution is difficult to describe quantitatively by only a separate simulation of dendrite scale or grain scale, and the numerical simulation of these two scales is difficult to render compatible. A three-dimensional cellular

Phase field study on crystal orientation effects in eutectoid phase transformation
Autor: Dong-qiao Zhang, Ya-jun Yin, Jian-xin Zhou
Publikováno v: China Foundry, Vol 14, Iss 5, Pp 435-442 (2017)
In this present work, a multi-phase field model was used to simulate the eutectoid transformation process, and on the basis of the nucleation model that was previously proposed by our research team, anisotropic and orientation relationship models wer
