Selective laser melting (SLM) of CX stainless steel: Theoretical Calculation, Process optimization and strengthening mechanism
Journal of Materials Science & Technology, 1Co-Authors: Dongdong Dong, Chang Cheng, Hao Wang, Xingchen Yan, Min Liu, Sihao Deng, Julien Gardan, Rodolphe Bolot, Hanlin LiaoAbstract:Abstract In the present work, selective laser melting (SLM) technology was utilized for manufacturing CX stainless steel samples under a series of laser parameters. The effect of laser linear energy density on the microstructure characteristics, phase distribution, crystallographic orientation and mechanical properties of these CX stainless steel samples were investigated theoretically and experimentally via scanning electron microscope (SEM), X-ray diffraction (XRD), electron backscatter diffraction (EBSD) and transmission electron microscope (TEM). Based on the systematic study, the SLM CX stainless steel sample with best surface roughness (Ra = 4.05 ± 1.8 μm) and relative density (Rd = 99.72 %±0.22 %) under the optimal linear density (η = 245 J/m) can be obtained. SLM CX stainless steel was primarily constituted by a large number of fine martensite (α’ phase) structures (i.e., cell structures, cellular dendrites and blocky grains) and a small quantity of austenite (γ phase) structures. The preferred crystallographic orientation (i.e., direction) can be determined in the XZ plane of the SLM CX sample. Furthermore, under the optimal linear energy density, the good combinations with the highest ultimate tensile strength (UTS = 1068.0 %±5.9 %) and the best total elongation (TE = 15.70 %±0.26 %) of the SLM CX sample can be attained. Dislocation strengthening dominates the strengthening mechanism of the SLM CX sample in as-built state.

Visualization of Calculation Process in Thermo-Fluid Analysis Using Spreadsheet of Excel
Journal of the Visualization Society of Japan, 2005Co-Authors: Masaaki Okuyama, Toshio TomimuraAbstract:In the numerical analysis using the spreadsheet of Excel, the image of the physical model can be drawn on the worksheet, and both programming and debagging are performed visually via classification by coloring of interior and boundary cells, where corresponding difference equations are embedded. Furthermore, calculated results can be shown and at the same time confirmed immediately by using the accessory graph wizard. In the present study, a newly developed visual-oriented numerical method for solving the two-dimensional steady-state mixed convection problem which applies the upwind-difference scheme is explained through a simple physical model of inclined parallel plates with discreet heat sources.

Visualization of Calculation Process in Numerical Analysis Using Spreadsheet of Excel
JOURNAL OF THE FLOW VISUALIZATION SOCIETY OF JAPAN, 2004Co-Authors: Toshio Tomimura, Shigeki Hirasawa, Mitsuaki HanedaAbstract:A new visual-oriented numerical method which applies the spreadsheet of Excel has been proposed. In the present study, a programming Process on two-dimensional steady-state heat conduction problem in the rectangular coordinate system is explained by way of a specific example, where a volumetrically heat generating rectangular region with a concave is heated uniformly at one wall and other walls are kept at some temperatures. The present steady-state numerical Calculation has been realized by introducing icon cells in which difference equations concerning the inner, boundary and singular points etc. are embedded. Through the programming Process using this specific model, the proposed method is shown one of the useful numerical methods.
